Meta Muse Wonder arrives, and Muse Code joins Token Tunnel

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, 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.

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.
