Together AI Adds Meta’s Muse Spark Open With Token Pricing

Together AI has added Meta’s Muse Spark Open to its serverless platform, giving developers hosted access with separate rates for input, output and cached input tokens. The model is also available through the Together API and playground, with dedicated infrastructure as another option.

Pricing is $1.25 per million input tokens, $4.25 per million output tokens and $0.15 per million cached input tokens. Muse Spark Open has 816 billion total parameters, including 42 billion active per token, and a 1 million-token context window.

The model is built for long-running coding workflows, computer use, web automation and multimodal tasks. Meta released its weights Oct. 15, allowing developers to run the model locally on Mac Studio clusters alongside hosted deployment options.
