Meta Muse Wonder in chat: 1M context, image and PDF input
Meta's Muse Wonder is available in FastMetal chat. Meta announced it on October 12, 2026 and calls it its most capable model yet, the frontier model of the Muse line. Meta released a larger Muse Wonder Full at the same time for its own coding products; FastMetal serves Muse Wonder.
Muse Wonder is a chat-only model on FastMetal: you use it in the web chat, and it is not available through the API or MCP.
What it is built for
- Personal and work agent tasks. Meta's model card names research, planning and multi-step work with tools as the main uses.
- Specialist documents. Meta expects it to read legal, financial and medical material, pull out the key points and draft text for review.
- Coding. The uses Meta lists run from writing, explaining and debugging code to sustained work across a large project.
- A 1M-token context. We serve it with 1,048,576 tokens, enough for a long contract or a full set of documents in one message.
- A reasoning model that reads images and PDFs. It thinks before it answers. Before launch we checked image input, and PDFs attached as files, with real documents.
Pricing
Muse Wonder is billed per million input tokens and per million output tokens. Thinking tokens count as output. Current rates are on the model page.
Billing is prepaid: you load a balance by card, from $5, and you can never spend more than you loaded. See pricing.
How to use it
- Create a FastMetal account.
- Load a balance.
- Open chat and pick Muse Wonder from the model list. Attach images or PDFs to a message as you need them.
