Meta推出Muse Wonder和Muse Wonder Full：基准测试、定价及使用方法

Meta has released Muse Wonder and Muse Wonder Full, its most capable models so far. Muse Wonder is a frontier model from Meta built for personal and professional AI agents. Both models target long-running agent work: coding, legal and finance tasks, and computer use. Muse Wonder is live now on the Meta Model API and Muse Code. Muse Wonder Full is limited to paid Muse Code plans. TL;DR Size: 1M-token context, input of text, image, video and audio, output of text. Runs on: Metas cloud only, via the API or Muse Code CLI (macOS, Linux, Windows). Performance: Muse Wonder Full leads 6 of 14 rows in Metas benchmark table. It trails Claude Opus 5.5 on several. Best: Muse Wonder scores 85.6 on MemoryBench, the top result among all 5 models listed. Worst: Muse Wonder scores 50.0 on ProgramBench, against 70.5 for Claude Opus 5.5. What is Muse Wonder? Muse Wonder follows Muse Spark on Metas scaling ladder. Meta team states that it was trained at its Prometheus data center, with gains across pretraining and reinforcement learning. Meta credits a larger base model for better results on unfamiliar tasks. Two named behaviors define the release: Active Memory: carries user context across conversations and pulls back the details a task needs. Active Focus: keeps working on hard tasks, tries alternatives, and checks in before important actions. For developers, Muse Wonder plans long tasks and delegates to sub-agents. It also operates browsers, desktop and mobile apps. How does Muse Wonder perform on benchmarks? All scores below come from Metas published table at max reasoning effort. Several rows use third-party sources such as Artificial Analysis, Vals AI and Datacurve.

The model card says competitor runs are best-effort and may not be tuned. SWE-Marathon results for rivals used Codex and Claude Code, so it is not a common-harness comparison.

Click Start building to sign in. The Muse Code install command sits on the same page. Step 2: Pick your model. Muse Wonder costs $4 input, $0.20 cached and $20 output per million tokens. Muse Wonder Full needs a Muse Code plan: Power at $50 or Maximum at $200 per month. Step 3: Sign in with your Meta account. Confirm your name, accept the Model API terms, and click Get started. Step 4. Add billing, then create an API key. New accounts see a No payment method banner, and Create API key stays disabled. Add a card under Billing, then open API keys and select Create API key. Export it as , per the quickstart. Step 5. Test it in the Playground. Open Chat, pick , and set temperature, max tokens and reasoning effort. Step 6. Copy working code. Click Get code for a curl or Python snippet. It calls the Responses endpoint at . The API is OpenAI-compatible, so the OpenAI SDK works with a new base URL: Copy CodeCopiedUse a different Browser Step 7: Or use Muse Code in your terminal. On Mac, install with . On Windows, use . Run in your project folder, trust the workspace, and sign in. The default model is . Switch with , or launch with . Key Takeaways Muse Wonder ships at $4/$20 per million tokens with 1M context. Muse Wonder Full leads DeepSWE (79.0) and SWE-Marathon (57.5). Claude Opus 5.5 still leads ProgramBench, OSWorld and Terminal-Bench. Wonder Full is Muse Code only, from $50 per month.
