I have been using Claude for almost 2 years now. When everyone are talking about chatgpt, I installed the Claude code CLI on my Debian. Gemini was the similar tool at that time. I compared both and Gemini wasn't even creating a single function without errors and it was always apologizing for it's mistake. But Claude was way better than Gemini even in the beginning. Until now, I haven't switched to another LLM for coding. Now we're discussing about Pi, which has BYOK. What I think is, no alternatives can replace the native one when new feature are going to release, in any type of sofytware.

I used to use ChatGPT/Claude in the TUI up until like 3 months ago, but my usage of LLMs has exploded - many sessions across many projects. I feel like I outgrew the TUI and now I'm using ChatGPT/Claude desktop. VS Code has become a code review tool and place where I manage git if need be.
The GUI is less verbose with the nitty gritty hidden in expandable sections, which makes history easier and cleaner to scroll through, also no scrolling bugs, rich text is easier to read with tables, and images integrated into the chat, resources like browsers in the context of the session. Drag and drop session organization (pins), scheduled tasks, etc.. all that in the side bar.
Usually a TUI would be open in VS Code and scoped to whatever repo I'm working with so 10 projects, 10 VS Code instances open, not super scalable. With the GUI desktop app it's one app, and I can start sessions in an repo and switch between them easily, no need to open VS Code for each. I don't see what could make me want to go back to using a TUI.
Who else is just using the GUI nowadays, or are you still on the TUI, and why, have you tried the GUI interfaces?

I went from TUI and tested several GUIs that can also support a "TUI" view.
After testing several options at the moment I'm using Orca IDE as my daily driver - effectively as a layer on top anthropic / openai
- Supports both anthropic and openai with subscriptions and can you swithc easily between those two + other LLms
- Its a bit hidden / non intuitive to setup but it does support running everything on remove host -> I run (95%) of my jobs on remote hosts that I can both access from my laptop + their native app via a wirguard vpn
- You can switch between chatview + TUI on the same conversation - very useful if you move e.g. from desktop session to mobile view.
- For repeating LLM tasks Orca also suports a kind of scheduler - but I prefer currently to have the agent set things up via chronjobs on the remote machine (not super happy with this ...)
Key reason I dont want to go fully ChatGPT/Claude is also I dont want to build a super strong dependency on those mega players and remain the ability to switch to other interefernce providers / models.
As LLM usage is already a core workflow in our company - a sudden unavailability of one or a massive price increase - makes it absolutely necessary to build out alternatives.
We all know the downsides of SAAS Lock in too well from the 2010s. In that sense Fool me once, fool me twice..

+1 on the Orca and remote machine. I've basically turned it into my own Claw machine. It does super well at letting me remote in across 3 computers and phone and hitting all the same sessions. I have one master session that is always kept alive as my main "agent", and spin out other full sessions from that.
It solves the crappy user experience of the CLI vs using an SSH terminal in VS code. (Easy copy pasting, everything formatted correctly, etc.) I created my own version of artifact hosting with a simple "mailbox" page on the box - every session can drop it's html reports off there nicely.
Completely agree on being able to flex out to different models. I'm using Claude Code as daily driver given the insane subsidies we are getting. But want something where I can switch easily onto the open weights, etc.

I find TUI scales better for multiple concurrent agents across the same and different codebases, especially using tools such as herdr. I can fire off an agent, which runs sub-agents. Then check-in periodically to re-steer as needed or be interrupt driven for completions of tasks. I can't see how vscode/GUI is better for this?

For me the tight integration with Claude Artifacts (and whatever OpenAIs copy of those is) is super value-able for me. The biggest bottleneck for me is gathering all my thoughts and analyzing what needs to be done.
I was a long term user of the TUI and tools like cmux / herdr but now I find it much easier to actually focus

I switched to the Linux desktop as soon as it was available to avoid all of the TUI rendering bugs and restore sensible copy/paste. I was using vscode's git panel to review diffs before they got committed, but had a feeling that there had to be a way to make agents pull harder so my review wasn't always the long pole in the tent.
Imagine a local GitHub PR web UI (thanks to difit), married to your agent for real time in-context discussions, and built-in skills to teach agents how to write easy to follow PR, focusing on both why's and hows.
Last night I released gavel that scratches this itch: it's open source, so fork and enjoy. https://photostructure.com/coding/gavel/

Haven't tried it yet.

Paseo has been pretty amazing at getting more autonomy. It's the way the agent profiles work. It is effectively a fully adaptive "auto-harness" with just the tiniest amount of config.
Fully switched from TUI 4 weeks back while testing it out for another use case.

I graduated from Claude Code to Herdr to now T3Code.
T3Code can do anything I might need such a tool to. It supports a bunch of different harnesses, therefore also subscriptions. It supports running agents on different servers, from the same GUI. Mobile app that works well. Orchestration that allows any agent to orchestrate others in T3Code directly.

T3 Code has a few weaknesses compared to Claude desktop but on the whole it is excellent. It’s my primary agentic coding tool right now.

I just ended up making my own GUI. I never really liked any of the pre-build ones. It started slow (3-4 days of work) and grew organically around my working style. I can also have my preferred UX (e.g., high information density).
Take a look at the Codex App Server or the Claude Agent SDK as a way to communicate with harnesses running headlessly and build your own UI on top. I’m sure Pi can be set up in a similar fashion.

I have the same setup. All you need is a server hosted on your own machine and a few adapters to connect them to providers using ACP and various thin client all connected through tailnet. I have developed my own web and mobile applications with gemini live full duplex routing to opus my local projects and maintain the same session across any platform I choose, including Hermes. Building personal software is easy these days.

I've been building my own open-source coding agent, VT Code, in Rust.
I wanted more control over the harness itself, especially tool execution, sandboxing, approvals, and context management.
Recently built a native macOS app with GPUI on top of the same agent runloop. It's been interesting exploring how the same engine works across terminal and desktop workflows.

I did this for myself several times. I started with winforms and evolved into a full blown clone of ChatGPT.com experience built as a razor/MVC project in .NET10.
I have 2 versions that are just for working on unity projects. One that is for working on the client project. There is also one that I refer to as the ring of power / Death Star that I keep mostly to myself. Eventually, the client saw what I was doing and decided they wanted a custom ChatGPT.com experience for the whole team, so I got paid to build the most recent one.
Using AI to assist with the development of this stuff is the RSI you've been looking for. I'm in a situation where I was only able to solve a problem due to two levels of bootstrapping enabled by custom harnesses. The product the client uses cannot be "one shot" using the latest frontier tools. I had to build an ad-hoc agent loop fit for just that one purpose using another tool that was possible to build via copilot. For example, using copilot in VS over a unity project's scripts might as well be a drunk person throwing darts from a boat compared to a purpose built harness that can execute ad-hoc scripts in the editor environment as often as it pleases.
The client's custom experience is better than ChatGPT.com in many important ways now. It certainly performs better. It will run on safari without doing horrific things to layout and my CPU. You can easily exceed the capabilities of the frontier AI companies in ways that are important if you use their tools cleverly. These companies are great at making AI models. Not harnesses, websites, apps, etc.

I went the same way but found that the GUIs (Claude and Codex Desktop) are still too low-level to scale well. They are basically just tabbed chat windows. I wanted more structure and more targeted UX for managing my work. It's easy nowadays to build your own GUI, so I did.
(I found it's still quite some work to polish it so that it's actually good. Therefore, sharing it could still benefit others, so I did: obeya.si, free, open-source)

I am not a terminal head, but I find it simpler to drop into a dir and codex from there. In the GUIs, I often mistakenly end up under the wrong tab (Chat/Work/Code) and if I am in Chat, sooner or later the thing will ask me to switch to Work. On the other hand, the GUI provides the history of threads. I semi defeated this by using hooks to write questions and answers to an SQLite db.

I’m being slowly forced to use a GUI at work, and it’s fine, but I simply prefer the TUI.
I use:
claude agents
Granted, I run it as a terminal tab in my editor so that I can look at files. I prefer the TUI in a tab instead of the editor’s half-assed plugin. These days, however, I mostly look at PRs in the browser.
For my personal work I still prefer to let the agent edit the local files so I can preview the changes in my editor. I avoid PRs in my personal work.

> now I'm using ChatGPT/Claude desktop
Same, it's lovely software for that mode of work!
I also briefly tried out other ADEs, like:
- Kepler (by the GitKraken folks) - https://www.gitkraken.com/kepler
- Paseo - https://paseo.sh/
Kepler had a really nice issue tracker integration but the UI was very vibey and not quite as to the point as I'd like (who needs graph visualization of what the agents do, just give me tools that work), and Paseo had a really nice UI that I could use to drive both Codex and Claude Code, but some OpenCode agents would sometimes hang and I didn't have tools to really do anything about it.
Maybe I should also give JetBrains Air a look again, if I ever end up subscribing to them again (I just moved to Zed for my code editing): https://www.jetbrains.com/air/
Interesting space, with so many additional tools popping up! That said, the OpenCode TUI was really pleasant too.
wccrawford 4 hours ago
I actually just decided to cancel my Jetbrains account, and your comment made me think about trying Air before I go.
I went to my Jetbrains Toolbox, and it's not there.
I went to the site, and there are 3 options:
Install it as a plugin to one of their other IDEs. This feels really stupid to me.
Air Teams. This isn't widely available yet, and you have to ask nicely and be put on a list. No go.
Air CLI. I honestly don't know WTF this is doing that I couldn't just do from the CLI with my existing agents. I already have Antigravity (for planning) using Claude for implementation and all I had to do was ask Antigravity to set it up.
They really need to get their stuff together over there at Jetbrains.

""GUI is less verbose with the nitty gritty hidden in expandable sections, ""
? The GUI has nothing to do with that.
If you use Chat / Work / Code <- that's the differentiation.
So 'Code' in 'Gui' is identical to Claude Code except for the visual layout.
If you use Work or Chat, which are not optimized for Coding you'll see a different experience.
If you use iTerm or Ghostty and set a key combo to switch tabs you can very easily switch between tabs and the TUI generally gives more dense information.
Usually people migrate to TUI not the other way around.
I think that there are reasons to use GUI - if there is deeper integration with Git or an issue tracker - or - in VSCode - for navigating files etc. - definitely those things are valid.
But for raw AI the getting a TUI to work the way you want it is ideal.
miki123211 6 hours ago
I don't get why people love TUIs so much. They're basically GUIs made using inferior tools. Why hammer in a nail using your fist if you have a hammer handy?
A GUI is strictly more powerful than a TUI (because a GUI could just show plain text in cases where that is the most appropriate mode of interaction, E.G. Bloomberg, AMadeus), but it could also do so much more in cases where it is not.
I do love terminals, don't get me wrong. When what you're interacting with is CLIs and Unix tools in a shell, a terminal is exactly what you want. I do love the Unix philosophy, I like small and composable tools that you can use together, and I think the interactive way of working that a shell or REPL can give you is great (though notebooks would have been better, but that's beside the point). Those are things that the terminal shines at. Pretending to be a GUI is not one of those things.

I thought the TUI was the ultimate power tool and loved the original embrace from claude code. I still use TUI a lot, but have been using deepseek harness web app atop my local model and am already liking the better organization and UI of this interface. I can see my load shifting to it. But you are right, you almost always need a VS Code interface open as well.
The outputs of Opus 5.5 were so much easier to read, but I do find the the deepseek web based tool much easier to comprehend for some reason. Plus I can access it from phone (over tailscale) as well when out and about and continue sessions very easily. AND it is all open source/weights. I'm pretty thrilled, but it's been less than a week.

Claude Web app includes Claude code tab with remote option to work from your own machine (if preferred). I am using it very often.
I have a project folder which is my default environment, and within it I have my many repo clones. That way I can work on any project from my prompt and reference elements in one project to include in another.

I've been using deepseek lately (just the chat interface on hobby stuff) and it's frankly better at searching the web and writes less like it's trying to bullshit its way through pretending to know what it's doing, i think it is just easier to understand. Unfortunately it also is more often wrong, or more often writes bugs, but i guess in a harness that's kinda mitigated -- it does usually find its earlier mistakes ime

I also like the inner text display of the GUI more, but the window management of it terrible IMO. On my Mac I have 3 desktops open, one for "private" and two for a project each. With the Claude TUIs I just have 1-5 open terminals per desktop, each with its title neatly set automatically. With the GUI app, I can only have 1 open, not one per desktop. It seems you can open several very reduced versions of the Claudr app with a single chat but that didn't work well for me. So that's why I'm still with TUIs..
jaapz 5 hours ago
Try herdr (or something like it). For me it fits exactly between claude desktop and having lots of open terminals.
The UI can be made to fit exactly the workflow you want to have.
I switched to it recently - my previous workflow was managing many terminals in a tiling window manager but I just kept losing track of stuff.

I switched to the GUIs half a year ago and never looked back.
From the text rendering and scrolling alone, they are much more pleasant to work with.
Conversations with activity and MR status indicators, nested sessions, images in the chat, and generally more information and functionality on the screen.
One negative is that it gives Claude, and particularly Codex, room to mess up with auto-opening artifacts.
Codex, when I was still using it, kept opening report or comparison pages in fullscreen when I did not ask for artifacts.
Claude loves to open its iOS simulator pane, but somehow never displays the one it's actually using, instead showing a simulator that is idle. It might be related to my custom tooling.

One of the very first thing you should do is stop using vscode’s terminal.
Use something like Rex, Ghostty, kitty or whatever floats your boat.
You will have a much better experience.
I use the terminal for most of my agentic workflows.
I still use vscode, but only for diffing and the proprietary devcontainer stuff.

I dislike the harness TUIs for this for the same reasons. Nothing against TUI in general, the lazy* universe for example is great.

You can drag and drop files in the TUI. You can also paste in images. With tmux you have forking, and tmux windows are fully scriptable, and controllable via your agent. I have them run shell tasks in tmux windows so I can see what they’re doing.

Some of it is the historical snobbery that CLI users have for GUI users. I count myself among them. Isn't it way cooler how I can fix my NIC with just three chained bash commands, while the windows users have to navigate 8 levels of dialogues?
But that mentality doesn't leave room for a lot of nuance. Even the most hard core TUI proponents and neovim gurus probably do not use Lynx as their browser (well maybe they use a vibe coded hacker news TUI client instead)

Pi is a good harness (I finally gave it a try w/ abliterated GLM), but not with Anthropic subscription, and there are multiple reasons to avoid alternative harnesses with their models in general (imho):
1. Potential ban due to ToS violation;
2. It doesn't follow all Anthropic's communication mechanisms out-of-the-box, they heavily use custom headers, hidden flags, and undocumented API features that affect models' behavior;
3. Compact is better in CC (significantly);
4. Cache related nuances (I mean, A\ regularly messes up with cache even in CC, their caching is non-trivial);
5. It's almost unavoidable to use Pi's extensions, and I wouldn't trust my oauth token to anything third-party (take a look at regular reddit/X posts where people getting banned due to such leaks and abuse) -> it takes enormous amount of hacking on top of Pi to get closer to CC abilities.
CC has hooks and mods, even ui_* (undocumented) protocol if you need some big customization, those are enough to implement whatever you want on top of CC.
Also, I'm working with CC from the very first versions, as for me - it's the best harness (as-is) on the market. I have zero clue what problems people are talking about (except known big issues, 3-4 over the years, I've never had serious problems, at all). Seamless and smooth experience, optimized for Anthropic models.
P.S. You can consider this as Stockholm syndrome effect, but... you have close to zero chances to get unbanned with Anthropic, and it's the best coding model(s) available today.
miki123211 6 hours ago
Most harnesses are not designed with conversations to be append-only from the start, which causes us all endless pain when caching is concerned.
When making a harness, it is so, so easy to do the "web thing" and have your system prompt be a template where you dynamically inject variables like the current date or the contents of the current working directory, and then just re-render that template on every request. THis is a bad, doubleplusungood, terrible, awful idea, and you should never do this under any circumstances. Anthropic will soon force you not to by literally refusing conversations that "break continuity" in this way and do anything but append new user messages at the end, but other providers at least appear to work.

I've only used CC and Pi and the point of pi is to use extensions. Luckily you can write them yourself pretty easily.
I cannot get behind CC is the best harness. Once u switched to pi I knew I was never going back and occasionally I need to use CC for my subscription and find it unpleasant. CC is just this incoherent hodge podge of functionality that seems to have no vision. Subjective, of course.
closetheloopdev 7 hours ago
I switch harnesses regularly depending on the model providers, and I only use skills which are universally usable in any model and harness combination. I don't want to get tied to a particular model or harness, and skills provide me the freedom to do so.
I can include any custom programs I need in a skill, and the SKILL.md file is just a doc of how to use those. It helps me save tokens and ensures determinism with repeated workflows since redoing a task is just calling a skill's program.
I also load only skills that are necessary for a project. I don't want to pollute the context window with unneeded skills.

I switched to Pi and it was great but I had to switch back to Claude Code purely for the subscription. Even with all the token efficiency I built into Pi it just wasn't nearly as good value as an Anthropic subscription. All open models ended up being more expensive so I switched to using an OpenAI subscription, which was better, but the OpenAI subscription is way less generous AND their models are behind. It became hard to justify.

I use both but I’m fairly new to Pi. For now things that I notably miss in Pi are plan mode and subtasks. I was also a bit surprised that it doesn't have default permission mode (deny all) like CC. It’d make sense when using an open router model. But I haven’t used extensions that much yet, so who knows what features I’m overlooking. I don’t see myself dropping CC for now though.

Using the Agent SDK to connect to Anthropic is an officially supported method and does not risk a ban.
I use a cheap deepseek model for compaction on purpose since it costs a penny or two and does not use any of my Anthropic quota.

Regarding credentials, my base instructions shared across all agents and all harnesses is that all credentials are accessed through a specific powershell script and should never be shown or written to file. This seems to work with pi, opencode.

I'd be curious to know the background around this. At work, I've used @anthropic/Opus 5.5 through Portkey with Pi, and ended up with $10 within less than 10 message exchanges, on a fairly trivial topic. OTOH, when using Claude Code directly with Opus 5.5, I basically spent $30 for a good back-and-forth across a full chat, reaching the point where CC kicked off compaction.

I agree. They are probably solving problems we don’t know are problems, beyond UX (like caching). That’s one of the reasons I prefer CC over Pi. Codex is pretty nice too, with respect to UX.

You can write your own compaction function for Pi, and you can even have different, domain specific compaction logic if you want. The default one is dumb, I agree.

Pi is without contest the best harness. Because it’s yours, the total control is the only way to move from driving agents to orchestrating them.
My interruptions and frustration with llms has gone down a cliff. It’s amazing to see what just a few lines of system prompt really can do to keep agents doing the correct thing much more often.
mark_l_watson 26 minutes ago
I tend to agree with you. I wrote 4 separate coding harnesses of my own earlier this year (in different programming languages, great learning experience), but pi running good local models like qwen 3.8 next flash, or a deepseek flash API from a vendor with decent privacy assurances is really the bedrock of my workflow. There are always exceptions: running pool harness with Laguna XS 2.1 6bit is a really nice local dev experience for code maintenance and quicker sessions. Also, I very occasionally really enjoy DeepSeek Harness with deepseek flash, CC with Opus 5.5 and agy with the latest Gemini Argon.
So there are many wonderful dev experiences, but generally relying on something relatively simple like pi makes a lot of sense, for my use cases.

I know people who really like OpenCode. I think the experience is pretty similar to Claude Code in that it's set up, out the box, with a specific wat of working. If you like it, then great, if not, you're kinda stuck.
Obviously you can add skills/rules/prompts/etc, but I don't find those are particularly great at being stuck to.

OpenCode is a worse design in several ways. But the worst part is they don't really respond to issues or pull requests and support is nonexistent. Been in multiple issues with a dozen people begging for a fix with no response. So we all do what we can but there's no one community fix. A ton of OpenCode functionality gets broken constantly because they have almost nonexistent regression tests nor e2e tests for all the features. When they do break it you have to go to Discord and hope someone from their team sees that they broke something, and hope they want to fix it or take a PR for it. This is also ignoring the massive memory leaks that were just accepted as normal.
But with Pi being barebones and intended to be customized, there are a million extensions to choose from compared to OpenCode. This means not only can you write your own extension easily, 5 other people already have. I forked one popular question-asking tool and added support for an external ui (Zenity). And an LLM provider (Synthetic) had a bug which I helped get fixed in a 3rd party extension for the provider. Both I got done in days, because I didn't have to go through some official Pi team; extensions distribute the work better. It's still hard to manage all the extensions, but better than the alternative.

> it’s yours, the total control is the only way to move from driving agents to orchestrating them
I wrote Juggler (https://github.com/juggler-ai/juggler) because I liked Pi's approach to everything being customisable and controllable, but I wanted a slick, navigable GUI rather than terminal hell.
...BUT: having gone to great pains to build an architecture around customisation, where every possible pluggable thing is a plugin, I'm starting to feel jaded on the whole "we need to customise it all" mentality. The models have got so good over the last year that I just don't think that tweaking the harness is something many people will need to do as things progress. The models only need a bare-bones set of tools to do everything they need, and I'm starting to think that UX and UI are the only really important things to focus on in an agent.
(Although from the perspective of coding a harness, making things plugins and having a plugin API does help to keep things clean and stops the codebase getting sloppy)

I’ve been using Pi since April. I switched from using copilot CLI which definitely isn’t the most frontier harness going but was more “feature rich” at the time than the stripped down feature set you get with Pi out the box.
The bit I was instantly drawn to was how much access you are given to change every part of it. Its similar to the text buffer in emacs where every cell in the buffer is fully accessible to any edits you need to make. My configurations are fairly minimal, but for instance I match the accept cli calls that could be destructive and edits to files in the same way copilot is set up.
Currently my pi config turns it into a tutor. It no longer makes edits, just advises and is designed to teach. I make all the code edits by hand. Use deepseek flash with it because its stupid cheap. It works for me, but honestly you can set up pi in any way you want which is why I personally think its the best harness by virtue of anything being possible as long as you can dream it up!

The author is complaining about Claude Code inside VSCode. The complaints don’t apply to the Claude Desktop App, for the most part. You don’t need VSCode to review code, just use the Claude app which has good support already. And if you’re moving to Pi, maybe use it with ThinkRail, from JetBrains. It’s my favorite harness since it can do everything I want: multiple models including local, focus on reviewing code after the agents are done, uses worktrees by default. And it adds some nifty tools for designing software which I am really enjoying. One thing it can’t do is let you edit files :) but that is ok, in the rare case I write something I use emacs, thank God no more need for a heavy IDE!

The harness doesn't matter as much as what additional value the company behind the harness brings.
Example: claude desktop + projects gives free compute for compilation without any cap (that I've found). So that + opus 5.5 which practically never runs out, and it's possible to get thousands of euros worth per month. On Pi/similar, the tokens + compute are metered and it quickly stacks up to something substantially more expensive.
Now this is clearly unsustainable, tip is to milk the cow for as long as it's possible

The Agent SDK is using the Claude Code harness. The point of using Pi is to avoid using that harness entirely. It wouldn’t make sense to use the Agent SDK in Pi; you would essentially be driving a harness with another harness.
If you’ve used Codex before, then the Agent SDK is Anthropic’s equivalent of the Codex App Server, which is Codex running headlessly with a protocol to talk to it.

Anthropic's subscription is the one that has historically been tough to use with other harnesses, where they have (had?) technical safeguards to ensure your subscription usage was limited to Claude Code CLI, with third party harnesses often implementing workarounds or faking it to use your Claude.ai subscription. Nowadays Jetbrains Air does officially allow using your Claude.ai subscription.
But OpenAI's subscription has seemingly always been available to use in other harnesses without trouble.

There is no stick unlike Anthropic (along with insisting on signing commits and "don't abuse the robot" the reason I started to use OpenAI instead of Anthropic --- not that I am under the illusion they are any less evil overall) but I think now there is starting to be a carrot towards Codex usage since there sessions are "cached forever".

Does Pi come with an auto mode that blocks dangerous actions? It didn't last time I checked, and these measures are critical to protect prod (and your personal files, etc) from a confused agent.
I gave the harness a try and it is refreshing, but the insistence on staying bare bones and not implementing basic functionality natively, together with no vetting process for popular 3rd party modules, made me return to Claude Code.

I would not trust auto mode in the first place.
Wrap your agent of choice in e.g. docker sandbox, nono.sh, Nvidia OpenShell, microsanbox or any other sandboxing tool and run it without any checks (i.e. "yolo mode", dangerously-skip-permissions etc.)
IMHO it makes the whole category of problems around permission fatigue, trusting the harness (or plugin) authors etc go away.

I've been using Cursor for a few years now, and while I'm well aware that it's more expensive, from a UX perspective I am 95% happy. There's still a few things like not being able to move conversations between folders or computers, but big picture, a lot to love. It's just a really coherent dev experience.
When I read what folks write about CC and TUIs it all sounds... really, really awful and I kind of don't get why any wouldn't want to use Cursor. I'm posting this to see if anyone wants to explain how/why I might want to ditch Cursor and go all in on Claude or Codex or Pi or anything else. I'm open to being convinced!
Mostly, I just want to understand. My sense of CC is that it's great for folks who are looking to spend lots of money having 4 agents one-shot an entire application from a single prompt so that they can pick their favourite when they wake up. Is that an absurd perspective? If so, tell me how you use it.
I'm someone working on fairly significant but personal projects; I have a very clear picture in my head about what I'd like to get so I tend to write extremely dense, detail-filled prompts and go through a multi-revision planning phase before kicking off agent mode on a feature. The apps I build tend to be the result of several dozen or several hundred features developed mostly serially, and I am always the bottleneck because of that whole "knowing what I want" thing.
So, that's my usage pattern. Should I be using Claude (or Pi)?

This is probably where the disconnect is - the TUI workflow only really clicked when I started working across multiple worktrees at the same time.
It’s not all or nothing. You can still be fully in the loop, read all the code and steer each session towards the outcomes you want. You’re just doing it across multiple branches at the same time and imo it’s easier to do that through the TUI.

The problem: This is not only about some pre-prompt instructions, its about coding instructions for different lanugages, frameworks and architectures and skill/hooks/tools for different purposes. I drowned in multiple setups (I have ADHD/ASS, I start two projects a week). So I decided to built this kind of "wrapper" that I can use with every new project.

I use both, and I think Claude Code is easier for beginners but Pi is more interesting to get a better understanding of what the harness is doing for you. Stuff like skills and MCP are sort of abstracted in CC in ways that obfuscate things, probably intentionally, while Pi lets you really see where a model got stuck and why. Inspecting thinking traces and dead ends from local models teaches you a lot about how they work in general.

Why do you limit yourself to mac?
You can run larger flash models on a modern PC using strata. These models perform pretty good even on low quants.
Furthermore, next generation open weight models will swap some compute for storage, making them more accessible for masses.

I am genuinely curious to know what kind of genuine problems people are solving with opus that cant be done with sonnet or the free models. If there are problems that people are working on that only opus 5.5 can solve then were we not touching such problems last year at all (because last years best model was inferior to sonnet 5.5). And if people are solving such problems now, why cant I see any meaningful improvement in even a single software I use everyday?
Not trying to diss on anything or anybody. I want to know.

Sonnet 5.5 feels like a cocky rookie. It's capable, but it often makes mistakes and especially poor assumptions, and when I point it out it just goes "yeah I did that wrong". Opus is much better at judging assumptions, makes less poor assumptions and mistakes. And when I point them out it takes it to heart and makes sure it guards against such a mistake in the future.
Sonnet is great for simple work, such as subagents running a program and summarizing the output. Opus is just that much better at the more challenging work I find.
You can probably get Sonnet to reach the same goal, but Opus needs much less hand-holding and overwatch.

From the article’s footnotes:
If you assume 1 million DAU and 100M requests per day, trimming 1,000 tokens off of [the over-long system prompt] could literally save millions of dollars in inference costs per year
That should be corrected to “could literally lose millions of dollars in inference revenue per year”, which also goes some way toward explaining why it doesn’t happen.O_H_E 10 hours ago

Alternatively, what you’re seeing is continuous hill climbing and optimisations based on large scale experiments and simulated rollouts.
For me personally, I don’t use Claude Code because I can’t read the source.
At least with Codex, I know there’s a bunch of telemetry and all that, but I can have my agent inspect the source and have relatively greater confidence it’s not implanting spyware onto my machine, because a classifier thinks I’m working for Deepseek or something.

Let's be real. If their tools were as amazing as they're touting, Claude Code would be a tight, hyper optimized Rust/Zig/FreePascal/whatever 3MB binary that would launch instantly, have no trouble scrolling text at lightning speed on its 20 platforms, etc, etc.

It’s not that unreasonable, or at least wasn’t a few years ago. I complained about the Chatgpt Pro $200 not allowing basically unlimited image generation (the limits were super low) a couple years ago and the next day Sam Altman tweeted asking about switching up how they handle Pro plans and putting usage into a single pool (which is what they moved to). If he didn’t read my email directly the gist at least got to him.

Something is misconfigured on your end. I have had some trouble where parameters were incorrect, but otherwise I have used several vendors (local, openrouter, ollama cloud, kimi, deep seek) and it generally works.
Most likely context length parameters aren’t set quite right for your model/provider and you genuinely run out of context during compaction

I never really rely on compaction. Instead, I instruct the coding agents to maintain a handoff markdown document across sessions. Ymmv.

Anecdotally I run semi nightly harness and local model test runs, and opencode consistently outperforms ohmypi on various code bench tasks.
Note though that this for local models that can run on a 5090, so, kinda dumb models with a small context window. Also they might perform differently on a custom pi setup rather than the very feature rich ohmypi.
Mostly the runs just cause me to get decision fatigue so I typically just use opencode and let a frontier model choose whatever cheaper models it wants to orchestrate with, so long as it's one that's not on the same token budget.
P.S. I'd always wondered who it was that got caleb.software before I could... Outshot in a western duel!

Alas Opencode's source is hideous to read.
When you say "kinda dumb" it's worth noting that the smaller coding models tend not to actually need system prompts to be helpful coding assistants, etc. Qwen maybe more than Muse Glimmer? I've not tested Qwen 3.8 27B enough yet. Even Gemma 4 didn't seem to need much.
Muse Glimmer is so absolutely tuned for one particular pattern (turn-by-turn agentic coding and assistance) that it will do it more or less without a prompt at all (except to set the reasoning level maybe). Beyond the tools announcement, it feels to me like it almost only needs a prompt to do plan mode stuff. If LM Studio (in either of its forms) or Unsloth Desktop had proper support for running inside a linux container rather than just a filesystem sandbox, you'd barely need a dedicated coding agent at all. Osaurus gets even closer.
I wanted to like Opencode but I can't, really. I am enjoying Pi slightly more because it's just way less convoluted and obscure.
FWIW I use Paseo for the GUI, which to some extent eliminates that aspect of decision fatigue; if you like Paseo's UI well enough, you can have it with almost any harness. And since it can connect to its daemon via ssh you can still have the desktop GUI with a container. (Not clear to me if Opencode v2 Desktop makes remote connections to the daemon or just wraps the web interface like v1 did)
load-bearing 10 hours ago
I do not know how it is with Glimmer, but other Facebook models (Muse and whatever is currently hiding under "Crouton") sure love ignoring direct instructions to do or not do something important (like not using particular broken/inefficient tools). Doesn't matter if it's repeated ten times in screaming caps, they'll still ignore it at least sometimes.
No other model I've used does this.

jijji 7 hours ago
I have tried Pi, but at this point I'm using a fleet of hermes agents to connect realtime via webrtc to a custom web dashboard (written in rust) that works on multiple projects/tasks atomically and simultaneously and compiles/tests locally and then submits to a private central git with all its changes and then pushes to dev for testing, then prod. The agents working on tasks can request new tasks and a supervisor is configured for each project that does a scheduled review and proposes recommendations based on what has been done and needs to be done based on the project plan...As new agents come online they can be quickly enrolled. It works well when you're working on many projects simultaneously. Its also a good use for a stack of 10 old laptops.

Unfortunately I have to use Claude Code at work, and it is a very frustrating experience, I constantly find myself trying to bend it to my will. I sometimes suspect that my distaste for Claude Code is one of the reasons of my distaste for Claude as well.
Pi on the other hand is a joy to use. Top notch session and model management, excellent conversation tree/branching functionality, and it lives up to its philosophy of being meant to be adapted to your workflow.
I can't recommend it enough, especially if you use alternative LLMs instead of Claude.

The whole AGENTS vs CLAUDE md issue was bound to be resolved. If the models are getting smarter and harnesses getting better - how could you have a product so dumb that it ignores whatever skills, instructions, references, other things that are part of the folder context it is mounted in.
Having claude code ignore agents.md just made it seem dumb. At this point, you probably don't need either.
