“contributor” pricing at $0.10/$0.20 is crazy cheap if it’s measuring up to Sol.

Definitely shows how important a user data flywheel is for RL and model improvement.

The previous version was, in my experience, the best free model available on OpenCode. It's been very good at simple/moderate tasks where I am precise in my ask and it doesn't need to make a ton of undefined assumptions. Hopefully this new version is also available on opencode for free.

Im a caveman writing c/cpp. Last time ms1.2 was even worth than DeepSeek v4f preview on internal benchmark. It just feels like extremely over fitting on certain paths.

I have opposite result: MS1.2 wrote C code without following original source code writing style, and no descriptive info why writing such code, DS4F or even Mimo seems better to me.

I have not tried Muse Spark for code, but I've been using it for a while to write Latin. I find it's one of the best at it, alongside Gemini. For example, I've recently been using it to translate the subtitles of the show I'm watching into Latin, to provide me with a bit more input. (I'm learning Latin, for context)

For folks who are impressed with costs, why does it matter to you? Is subscriptions not a thing? I may be missing something but only companies should really care about this I would think?

Some of us own and run companies? Cost per performance is a huge deal.

I am very impressed by this model so far. It's faaast and it seems to be just intelligent enough to do really well. It's UI work (simple python UI) is very clean and functional. The UX was 'there'.

Very keen to try this after using Claude Code over the last few months. Should I just point Claude Code to Muse Spark endpoint (because I'm familiar with Code)? What do people think of Muse Code or other coding agent harnesses?

Just try opencode, it comes with 1.3 contributor free.

Well thats very interesting. Thank you. Will be interesting to see how hard/easy it is to translate my Claude skills, loop design, etc to the new harness.

This kind of raises another question to me regarding the coding benchmarks, how much of it is model versus harness?

Coming from Claude Code, I initially went with opencode but switched to pi.dev after a while and I think I like it more. It's lighter weight. It's worth trying both.

Is everyone rushing to launch something before Astra tomorrow?
