Muse Wonder: Meta’s first frontier model wants to remember you

Meta’s Superintelligence Lab has released two large models, Muse Wonder and Muse Wonder Full, with a focus on long-term memory and agents. They are paid only, and Meta said nothing about open weights.

Meta says it is building “personal superintelligence”. On 12 October its Superintelligence Lab released the first models that could plausibly compete at the top: Muse Wonder and the larger Muse Wonder Full. TechCrunch calls them Meta’s first attempt at a frontier model.

What is new

Memory: Meta’s headline feature is what it calls “active memory”: keeping track of what matters to you over days, weeks and months. On MemoryBench, a test of long-term memory, Meta says Wonder beats Anthropic’s Fable and Opus and OpenAI’s GPT-6 Astra. On other benchmarks Meta reports scores comparable to Fable 5.1 and Astra. These are Meta’s own tests.

Agents that do not give up: Alexandr Wang, Meta’s AI chief, told CNBC the model was trained to try other approaches when a real-world task hits a roadblock, such as booking a dinner reservation, instead of stalling and asking the user.

Training: both models were trained at Meta’s Prometheus data centre in Ohio, which came online this year.

Who gets it, and at what price

Muse app: to use Wonder in Meta’s Muse personal agent, you need a $20 or $100 monthly plan.

Developers: Wonder is on the Meta Model API at $4 per million input tokens and $20 per million output tokens, roughly level with GPT-6 Sol or Claude Opus 5.5, according to TechCrunch.

Wonder Full: only for subscribers to Muse Code, Meta’s coding agent, at $50 or $200 a month. It is not on the API.

Meta said nothing about downloadable weights, ITdaily notes, a sharp break from the openly released Llama models that made its name in AI.

The trust question

Memory and agents are a powerful mix, and a sensitive one. Some Muse users have complained on social media that the agent read personal messages without permission. Meta disputes this; Wang told CNBC that users may have authorised access earlier in a conversation and then forgotten. An assistant built to remember everything will need to be very clear about what it has been allowed to do.
