Meta's Muse Wonder AI model launch
- Meta released Muse Wonder and Muse Wonder Full on October 12, with Zuckerberg telling the Financial Times Meta has caught up with OpenAI and Anthropic at the AI frontier.
- Meta's chart shows Muse Wonder Full winning 7 of 14 rows, but Artificial Analysis independently scores it at 56, below Claude Opus 5.5 at 58, and Wonder Full is not available via API.
- SensorTower shows Muse leading ChatGPT on Day 1 retention by 32 points but trailing by 4.3 at Day 14.
Meta is claiming parity with the leading AI labs on several agent-focused benchmarks, supported in part by independent scoring, which represents a shift from the Llama 4 setback. Independent evaluation places Muse Wonder Full below Claude Opus 5.5 overall, and Muse Wonder Full is not accessible via API, limiting developer reach.
