Muse Wonder will soon power the Muse personal AI agent, initially for subscribers, per Meta
More powerful Muse Wonder Full arrives first via Muse Code, Meta's AI coding tool
Meta says Wonder performs competitively against OpenAI and Anthropic on selected benchmarks for coding and complex reasoning
Meta's shares rose about 4% in afternoon trading on the announcement
Two headline capabilities: Active Memory carries relevant context across conversations spanning days or weeks
Active Focus keeps the model working through difficult multi-step tasks, trying alternatives instead of stalling
Muse Wonder hits the Meta Model API and Muse Code; Wonder Full is subscriber-only at launch, not on the API
Reported API pricing for Wonder: $4 input / $20 output per 1M tokens (not officially confirmed); consumer plans $20 or $100/month, Muse Code $50 or $200/month
Alexandr Wang, who leads Meta AI, says the system (internally nicknamed Watermelon) is trained to try different tactics when real-world chores hit snags
Meta says Wonder offers its "strongest safeguards to date" against cyber misuse — but those protections are only in the paid model
Meta says its AI team is tracking agent-related "incidents or issues" with Muse, including disputed claims that the agent accessed private messages
Wang says Meta is educating users on permission settings "to ensure that consumers can trust the product going forward"
