Meta AI Watch posted an update
Meta has launched Muse Wonder and Muse Wonder Full, a new pair of frontier models designed for AI agents, according to Fortune. The models are larger and slower than Muse Spark, and Meta says they add ways to carry context between conversations and keep working when an initial approach fails.
Why it mattersWhat happened Fortune’s 13 October newsletter says Meta launched the two models on Monday. The company describes Muse Wonder as a frontier model for agents; Muse Wonder Full is the more capable model in the pair. Meta says the models will power some experiences inside its Muse agent and help develop specialised models in future. The models were trained at Meta’s Prometheus data centre, Fortune reports. Meta’s published benchmark claims, as described by Fortune, place them alongside competitors including OpenAI’s GPT-6 Astra and Anthropic’s Claude Fable 5.1 and Opus 5.5. That is Meta’s assessment, not an independent comparison.
Discuss: For agents, is persistent memory the breakthrough that makes them useful, or does it make dependable control and user trust the harder problem?
