Muse Wonder is a frontier reasoning model from Meta, aimed at complex personal and professional agent tasks. OpenRouter listed it on 12 October 2026. It accepts text, images, video, audio and PDF documents and returns text, with a 1,048,576-token context window. The listed price on 5 November 2026 is $4 per million input tokens and $20 per million output. That puts it with the pricier flagship models, so it needs a clear job to earn the cost. It is closed: OpenRouter links no public weights, which differs from Meta's open Llama releases, and the licence is not stated on the pages we read. The limit is output, which is text only, and the price. Press coverage says Meta also sells access through its own model API and a coding product, but we read only the OpenRouter listing, so treat that as unconfirmed. It suits teams that need audio, video and PDF input in one model. Figures come from OpenRouter's public model list and model page. We have not run it.
