Summary
On October 12, 2026, Vercel made Meta's Muse Wonder available through AI Gateway with a single API key and no separate Meta account. The model targets coding, long-running agents, and computer use, with a 1M-token context window, text/image/PDF input, tool calling, and structured output.
What changed
Muse Wonder (model id meta/muse-wonder-1.0) can be called via Vercel AI Gateway using one AI_GATEWAY_API_KEY, through the AI SDK or an OpenAI-compatible Chat Completions endpoint, with usage and cost tracking, routing, retries, and failover. Vercel documents setup paths for the fx agent and Claude Code.
Why it matters
It gives agent builders single-key access to a Meta model purpose-built for multi-step, multimodal agent work (planning, sub-agent delegation, and error recovery) without managing a Meta provider account, lowering integration friction for computer-use and coding agents.
