Meta has been one of the most interesting companies of the generative AI era — initially gaining a loyal and huge following of users for the release of its mostly open source Llama family of large language models (LLMs) beginning in early 2023 but coming to screeching halt last year after Llama 4 debuted to mixed reviews and ultimately, admissions of gaming benchmarks.That bumpy rollout of Llama 4 apparently spurred Meta founder and CEO Mark Zuckerberg to totally overhaul Meta’s AI operations in the summer of 2025, forming a new internal division, Meta Superintelligence Labs (MSL) which he recruited 29-year-old former Scale AI co-founder and CEO Alexandr Wang to lead as Chief AI Officer. Now, today, Meta is showing us the fruits of that effort: Muse Spark, a new proprietary model that Wang says (posting on rival social network X, used more often by the machine learning community) is “the most powerful model that meta has released,” and has “support for tool-use, visual chain of thought, & multi-agent orchestration.” He also says it will be the start of a new Muse family of models, raising questions about what will become of Meta’s popular lineup and ongoing development of the Llama family. It arrives not as a generic chatbot, but as the foundation for what Wang calls “personal superintelligence”—an AI that doesn’t just process text but “sees and understands the world around you” to act as a digital extension of the self, echoing Zuckberg’s public manifesto for a vision of personal superintelligence published in summer 2025.However, it is proprietary only — confined for now to the Meta AI app and website, as well as a ” private API preview to select users,” according to Meta’s blog post announcing it — a move likely to rankle the literally billions of users of Llama models and the thousands of developers who relied upon it (some of whom are active participants in rival social network Reddit’s r/LocalLLaMA subreddit). In addition, no pricing information for the model has yet been announced.It’s unclear if Meta has ended development on the Llama family entirely. When asked directly by VentureBeat, a Meta spokesperson said in an email: “Our current Llama models will continue to be availa …
