Meta Launches Muse Wonder, Claims It Beats OpenAI and Anthropic on Sustained Agent Benchmarks
kimmonismus · x · 2026-10-13
Meta has officially released the Muse Wonder series (Muse Wonder and Muse Wonder Full), claiming state-of-the-art performance on personal and professional agentic tasks. On DeepSWE it reportedly outperforms all other models including Claude Opus 5.5; on SWE-Marathon its reported score is 57.5%, versus 46.3% for Claude Opus 5.5 and 42.5% for GPT-6 Astra.
The models introduce Active Memory (retrieving relevant context across conversations) and Active Focus, and were trained at Meta's gigawatt-scale Prometheus data center — the result of a 14-month ground-up rebuild of its AI stack, aiming at "personal superintelligence." Muse Wonder is available via the Meta Model API and Muse Code, with Muse Wonder Full for Muse Code subscribers.
