Muse Spark Open free on Together AI until Oct 18, then $1.25/M input + $4.25/M output
togethercompute · x · 2026-10-16
Together AI is offering Meta's new open-weight Muse Spark Open for free via its Serverless API through October 18, 12 PM PT. After that, requests route to a paid endpoint at $1.25/M input + $4.25/M output tokens.
The model is positioned as a coding-optimized agentic model: higher first-attempt accuracy, reliable tool calling, and deep codebase understanding, with a 1M-token context for whole repositories. It supports multimodal browsing, subagent orchestration, unified computer use across desktop/mobile/browser, plus audio and audio-video perception. Caveats: new accounts must add a payment method and buy $15 in credits to activate, and Together may end the promo early.
