Muse Spark 1.2
Meta Superintelligence Labs' flagship line, and Meta's entry into the agentic coding market via the Meta Model API rather than open weights. Muse Spark plans work, delegates to subagents, writes scripts or drives UIs directly, and debugs from screenshots. It pairs a 1M-token context window with full multimodal input (images, video and PDFs) plus built-in search with citations, structured output and parallel tool calling.
Muse Spark 1.2 is a multimodal AI model from Meta. It costs $1.250 per million input tokens and $4.250 per million output tokens (blended $2.150/M), with a 1,049,000-token context window.
