Meta's Muse models: Wang claims they beat rival AI, scores still unpublished
Overview
Alexandr Wang, Meta's AI chief, says on X that Meta's Muse model matches or beats Astra, Fable and Opus on every technical benchmark his team ran, and that Muse Wonder Full Max may be the best AI model now.
Wang's first post names no benchmarks or scores. A repost he shared says Muse Wonder Full Max outperformed Opus 5.5 Max and GPT-6 Astra Ultra in head-to-head tests run through Muse CLI on a $50 Muse Code Power Usage plan, and promises full results on cost, completion time and performance later.
Rohan Paul, a separate X poster, reports that Muse Wonder beats Opus 5.5 and GPT-6 Astra on each benchmark he cites. The widest gap he gives is on SWE-Marathon, where Muse Wonder scores 57.5 against 46.3 for Opus 5.5. No published results from Meta support these figures yet.
