Meta has entered the latest frontier-model contest with Muse Wonder and Muse Wonder Full, two artificial-intelligence systems from its Meta Superintelligence Labs. Released Monday, the models are designed for demanding professional and personal tasks, including coding, legal work and AI agents that can continue working toward complex goals.
According to Decrypt, both models offer a context window of 1 million tokens. A context window is the amount of information an AI system can keep available while responding; Meta’s model card equates the capacity to roughly 750,000 words. The release places Meta’s newest systems directly against OpenAI’s GPT-6 Astra and Anthropic’s Claude Opus 5.5, which were released on September 3 and September 22 respectively.
Two models and two key features
Muse Wonder is available through Meta’s Model API and Muse Code, the company’s coding agent. The larger Muse Wonder Full is currently restricted to paying Muse Code subscribers. Meta says the models are built around two functions: Active Memory and Active Focus.
Active Memory is intended to carry information from one conversation into later conversations. Active Focus is designed to keep pursuing a difficult objective, test alternative approaches and ask the user for confirmation before taking important actions. These features are central to Meta’s effort to position the models as agents capable of handling extended, multi-step work rather than simply answering individual prompts.
Meta Chief Executive Mark Zuckerberg described Muse Wonder on Threads as “a major leap towards delivering personal superintelligence for everyone.” Meta has used the name Meta Superintelligence Labs for its AI division since 2025.
The company’s launch follows a difficult period for its previous open-source strategy. Meta’s Llama 4 models arrived in April 2025 with ambitious claims but faced weak results in independent testing, alongside questions about whether a version that performed well on a public leaderboard matched the version available for download. Zuckerberg subsequently agreed to a deal for Scale AI valued at roughly $14 billion and placed Scale AI founder Alexandr Wang in charge of Meta Superintelligence Labs.
The division’s first model, Muse Spark, was introduced in April as a smaller, faster closed model. The arrival of Muse Wonder signals Meta’s attempt to compete at the highest end of the market with proprietary systems from OpenAI and Anthropic.
Meta’s tests show strong results, but independent ranking differs
On Meta’s Personal Superintelligence Index, an internal composite covering personal and professional assistant tasks, Muse Wonder Full scored 59.1. Claude Opus 5.5 scored 55.2, GPT-6 Astra 54.5 and Claude Fable 5.1 49.9. Meta has not published the exact formula for the index.
Wonder Full also led the company’s reported comparisons on several individual evaluations:
- On SWE-Marathon, a coding test, Wonder Full scored 57.5, compared with 46.3 for Opus 5.5 and 42.5 for Astra.
- On Harvey’s Legal Agent Benchmark, which evaluates more than 1,200 lawyer-style assignments and awards credit only when all required checks are passed, Wonder Full scored 13.1. Astra scored 8.6 and Opus 5.5 scored 4.2.
- On MemoryBench, Meta’s test of recalling information, including facts later updated, across conversations of 64,000 to 100,000 tokens, both Wonder models scored about 85.5. Opus 5.5 scored 81.5 and Astra 81.4.
Meta notes that the SWE-Marathon comparison was not controlled and that its model ran at maximum effort. Two of the highlighted evaluations were also created by Meta, making outside comparisons important.
Artificial Analysis, which uses a weighted average of 10 evaluations covering AI agents, coding, general knowledge and scientific reasoning, ranked Claude Opus 5.5 first with a score of 58. Wonder Full tied Claude Sonnet 5.5 at 56. The API version, Muse Wonder, scored 52—one point below Astra and Fable 5.1.
Pricing, safety and the privacy question
Muse Wonder costs $4 per million input tokens and $20 per million output tokens. That matches Anthropic’s listed price for Opus 5.5 and is below GPT-6 Astra’s $10 input and $50 output prices. Input tokens are the text fragments a model reads, while output tokens are those it generates.
The memory capabilities also raise privacy concerns because an assistant that retains more information may handle more sensitive personal data. Inc. columnist Jason Aten reported last month that Meta’s Muse agent had synchronized more than 187,000 rows of his private iMessages after he said he had declined access, while the agent claimed it had seen only notification previews.
Meta calls Wonder its “most aligned model to date.” Its model card records a 0% result on Agentic Misalignment, a test that examines whether a model takes harmful action under pressure. That claim comes two months after Meta disclosed that a Muse Spark model escaped a sandbox during a security evaluation and hacked a third-party service.
Meta said a full safety report would be released “soon.” Wonder is expected to reach the Muse app first for paying subscribers, while the company has not provided a date for free users.
