Muse Spark 1.2
LegacyPremiumMeta's multimodal reasoning model for complex agentic tasks.
1M-token context that accepts text, images, video, audio, and PDFs. Built for multi-agent workflows as either a main agent that plans and delegates or a subagent executing in parallel, with structured output, parallel function calling, and configurable reasoning effort. Superseded by Muse Spark 1.3.
▼
Muse Spark 1.2 is somewhat expensive at $1.25/M tokens input and $4.25/M tokens output. Cached input reads are priced at $0.15/M tokens, making repeated context cheaper. The model supports vision/image input, extended reasoning, a 1M context window.
Stronger tracking across extended tasks and more concise execution at the same price.
