That sounds really quite interesting- one question pops up, this sounds like it could produce a lot of non-cache input tokens. How much impact does this have, and are you mitigating it?

Interested in adding support to my own 3code- https://3code.capocasa.dev- which aims to reduce cost by using more compact system prompts and a clever compaction variant.


I'm here for the long haul!

https://3code.capocasa.dev

I believe software can be done- with incremental improvement and keeping the foundation, like vim. That's the 3code trajectory.

New fun ideas go into seperate tools, possibly ones 3code (or other minimal agents) can call, but the core stays lean.


I agree! MCP should be a command line tool wrapper than can be used from any minimal agent without bloating context if you don't need it.


I did some token tests and both pi and my own 3code used 4x fewer tokens than Claude Code, while opencode used 2x fewer tokens than Claude Code. You can tell Anthropic just doesn't care about using tokens and the tradeoff is maximal performance. That's understandable, but it might not be the tradeoff you need, hence, alternative clients.


I went for a middle ground in https://3code.capocasa.dev.

Each family gets their own system prompt, based on the original harness one, but compacted and includes instructions for more brevity.


I made just that!

Written in Nim. Unixy scrollback but cross plaform. Tested for token efficiency.


Or for something not quite as bare bones- batteries included and tested for token consumption- https://3code.capocasa.dev


"Terse output is a design decision in 3code; pi's chattier reply style is a design decision in pi."

Can you elaborate?

What are the decisions that lead to this difference and what are their pros and cons?

I noticed Pi being chatty, but I assumes this was a model issue (DS4.1F).


Nice! I've seen it around on the Nim forums. Is it terminal only or do you plan to make use of Nim's JavaScript backend at some point to make a web UI too?


Thank you!!! And thank you for your interest!

Yes- I plan to make a a full web app, as well as a web-and-terminal orchestrator app. Still planning the details.


I'd be very interested especially if ACP (https://agentclientprotocol.com/get-started/introduction) was supported over stdio so when I'm not using it directly in the terminal, I could also use it in my other ACP frontends.


Last time I tried Mistral large it was pretty bad at programming but I hear they're fairly good at European language legal.


This is such a breath of fresh air


Not for the Sami people who have to inhale the rocket exhaust blast.


Istar's Spectrum rocket does not use RP-1 (kerosene), like Falcon 9 and Electron, which burns very dirty.

They are using liquid propane, which burns extremely cleanly, especially when combined with their liquid oxygen.

There is a lot of noise, but that should be the only pollution generated by this launch.


The first and second stages being disposed of aren’t pollution?


Yeah, that's fair. I was thinking only locally. However, I would hope they are dropping both stages somewhere relatively responsible. I guess I don't know where that is for polar orbits.


Oops, correct spelling is Isar.


I saw that very much developing 3code. Even slight system prompt variations can have huge differences in results, so I have one system prompt per model family.
