Muse Spark is a natively multimodal reasoning model with support for tool-use, visual chain of thought, and multi-agent orchestration.
Muse Spark 1.1 by meta is offered by 12 providers on this page. Its official list price is $1.25 per 1M input tokens and $4.25 per 1M output tokens.
Artificial Analysis rates it 53.2 on the Intelligence Index, with 71.3 for coding and 39.7 for agentic tasks. Against its lowest blended price of $2.00 per 1M, that is roughly 27 index points per dollar, which is the value ratio the leaderboards rank on. Median output speed is 199 tokens per second, with 1.41s to the first token. Running one task of the Artificial Analysis suite costs about $0.2923, which reflects how many tokens its reasoning consumes rather than the unit price alone.
The context window is 1,048,576 tokens at the reference host, but hosts report different limits, from 1,000,000 to 1,048,576, so the usable window depends on the provider you pick. It supports reasoning, tool use, and structured output. Accepted input modalities are Text, Image, PDF, Video, and Audio. Providers report the capability flags inconsistently, so verify a specific feature against the host you plan to use.
Quality is independently evaluated by Artificial Analysis. Speed/latency are model-level medians.

The same benchmark scores very differently across harness / dataset, so the qualifying conditions must be shown together.
