Ive been poking with the muse code binary - seems to be written in rust, looks similar to codex but either its a very hard fork (i also see dissimilar things like config format is different, no acp, etc) or is just heavily inspired by it (more likely).

Pricing: https://dev.meta.ai/docs/pricing-rate-limits

Interesting that they have separate API pricing for "we can train on your data" (whereas iirc most of the big players either make that distinction only between subscriptions and API usage, or train on everything). Wonder how it compares to Deepseek V4 Flash given that they're similar on pricing and data policy.

Is this becoming a race where we have a usual flow of a company .. AI models, Coding agents, image generation tools, and more AI models ?

Does this muse code have any muse spark 1.2 usage included? Can't understand from the docs.

Why does every AI lab feel the need to build their own coding agent…? Don’t we have more than enough already?

I wish they would add a ZDR endpoint on OpenRouter

Muse Spark 1.1 was released July 16th, less than a month ago. A new version release this soon (particularly after Kimi K3's release drastically overshadowed it) is a bit sus and it appears that Meta is trying a first launch do-over.

> Muse Spark 1.2 is available today in Muse Code and in Meta Model API with expanded global access

Wasn't the previous one us only? This is probably the biggest part of the post

Anyone know if muse code is open source?

Open the weights.

Interesting, it seems like their muse code is built upon Codex CLI?
