Meta: Muse Spark 1.1

Meta: Muse Spark 1.1 is a paid model from Meta that accepts text, image, video, and file inputs. It offers a context window of 1,048,576 tokens and allows up to 943,718 completion tokens, so a single request can carry large documents, long transcripts, or mixed media alongside very long outputs. It supports tool calling and reasoning. Structured output support is not specified, so teams that depend on strict schemas should test it before committing. At $1.25 per million input tokens and $4.25 per million output tokens, it suits buyers who need long context and video or file input but want to keep per-token costs moderate. It has no independent benchmark coverage yet, so its quality relative to alternatives is unproven. Shortlist it for long-context or multimodal trials, and run your own evaluations against established options before adopting it for production work.
