Meta released Muse Wonder on October 12, and it's in General Input the same day. You can also connect a Muse Code subscription through [Token Tunnel](/token-tunnel), alongside Claude, ChatGPT, Gemini, and Grok, and run Muse models on the plan you already pay for. Read about [Meta's earlier open-source Muse release](/blog/meta-open-sources-muse-spark-1-2).

### Muse Wonder

- A 1M-token context window, $4 input and $20 output per million tokens, $0.20 per million cached input tokens, and effort from minimal to xhigh.
- A default agent model, so specialists can run on it.
- Served through Vercel AI Gateway and OpenRouter. When it's overloaded, runs fall back to Claude Opus 5.5, then GPT-6.1 Sol, both in the same price tier.

### Muse Code on Token Tunnel

- Sign in with a device code from Meta, the same flow Grok uses.
- The tunnel offers Muse Wonder and Muse Spark 1.3. Muse Code's contributor variants, which train on your data, are never offered, and a test enforces it.
- Muse follows instructions reliably only when they arrive as a real system prompt (5 in 5 runs, versus 1 in 5 otherwise), so the tunnel sends them that way. Our tunnel test suite caught this before release.

### Also shipped

- Claude Haiku 5.5 on a Claude subscription now reliably answers as your specialist, held 10 of 10 times in testing.
