    If you got the $20 in free credits from Meta for signing up when muse-spark-1.1 was release, please note that there's now small print stating "While using free credits your content may be used for product improvement" which was not present at muse-spark-1.1 launch when the credits were given out.

    If you don't mind Meta retaining your data, the "Contributor" pricing is deepseek-v4-flash-level of low, roughly 1/10th normal muse-spark API pricing currently. Attractive if you're OK with them retaining and using your data.

    Ive been poking with the muse code binary - seems to be written in rust, looks similar to codex (i assume they took some inspiration) but either its a very hard fork or has no connection to it at all.

    This is a nice release and a solid improvement over Spark 1.1. It compares favorably with Grok 4.5. Not SOTA, but solid releases. I think they need to really get this more competitive with Deepseek V4 Flash / Luna pricing to move the needle.

      If you are happy to share data for training, the contributor mode offers amazing price $0.10 / $0.20

    Last I heard, everyone at Meta was using Claude Code.

    Any insiders know how Muse Code is doing internally?

    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 ?

    Very interesting they have a way cheaper "contributor" version "used to improve our products", how much of that is price discrimination vs the data being that valuable?

    Roughly DeepSeek V4 Flash pricing, though you can get V4 from providers that don't train on your data

    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.

    I wonder why they didn't compare with GPT-5.6-sol, only Terra?
    • woadwarrior01 37 minutes ago
      Haven't you seen the kernel optimization case study at the bottom of the page? They compare against GPT-5.6 Sol and their model is worse.
    • wmf 43 minutes ago
      Clearly they're positioning it as a mid model.
      • minimaxir 37 minutes ago
        Which is in itself a bit weird as mid models nowadays are a golden mean fallacy. Terra is much less popular than both Luna (cost-sensitive) and Sol (performance-sensitive).

        Claude Sonnet is a weird exception to the mid models because Anthropic doesn't do much with Haiku and Opus is too big.

    • logicchains 42 minutes ago
      Presumably because it's worse than Sol, same reason they compared it to Opus 5 not Fable.

      Their bigger model is not ready - watermelon code name was still being prepared for release as of a month ago

    Why does every AI lab feel the need to build their own coding agent…? Don’t we have more than enough already?
  • giancarlostoro 14 minutes ago
    Will someone at Meta for the love of God make it so none of this stuff goes through Facebook.com? You want customers but most corporate firewalls block social media. Also, a lot of devs do not want their work stuff tied up to their facebook account. For the love of all things show the IG / FB logins as optional and do email as primary.

    I am not a fan of Meta but I do cheer for any competitors against OpenAI and Anthropic, the duopoly is getting tiresome.

      +10000 to that

    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.
  • liviux 22 minutes ago
    Does this muse code have any muse spark 1.2 usage included? Can't understand from the docs.
  • Bolwin 39 minutes ago
    > 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?

  • fcoury 21 minutes ago
    Interesting, it seems like their muse code is built upon Codex CLI?

    Lol worse than DeepSeek
  • qphe95 39 minutes ago
    Theres no actual evidence they didn't just distill Kimi K3
    • Jabrov 4 minutes ago
      Is there any actual evidence that they did?
    • toephu2 24 minutes ago
      At this point, it doesn't matter who is distilling from who.

    Muse Spark 1.2 is a coding-focused update to Muse Spark 1.1, with improvements in code generation, complex debugging, codebase understanding, and end-to-end developer workflows. In Muse Spark 1.2, we significantly scaled up training compute on coding tasks while expanding training environment diversity. The model also maintains its strength in other key areas like general agents.

    If anyone from Meta is reading, please can you publish the cost and latency for each of your benchmarks, like OpenAI does? Show us how the reasoning effort level affects them in 2D charts. This needs to become standard practice.

    First of all, you have login to use it. Why?

    After everything that you have seen with Meta, would you really trust them with a coding agent? You don't even know if your prompts are being analyzed by them on the side or if your code base is being uploaded to them. This goes for the rest of them that have closed harnesses and closed models gated by a login.

    Think twice before falling for this announcement and ask yourself what they are not telling you.
