    AI for Security has never been more exciting. Let me present MAPTA, our multi-agent framework that found multiple (now confirmed!) Remote Code Executions (RCE's) in flagship web products of Tier-1 companies. Why the secrecy? We're good boys, letting them cook patched through

    very much appreciate this figure, it shows what matters: normalized results at the cost dependency

    Replying to @Xbow
    3/ Cost is becoming just as important as raw capability. Lower-cost models like GLM-5.2 and Muse Spark 1.1 showed that “good enough” offensive capability is becoming increasingly affordable, while Grok 4.5 delivered near-frontier performance in the mid-budget range.

    Today we're also opening the weights for Muse Glimmer, a great 30B parameter dense model that can run locally. Soon we'll also release the weights for Muse Spark 1.2, our latest foundation model. Meta is a strong supporter of open source and I'm proud of these releases. Congrats
