Together AI now hosts Meta’s Muse Spark Open for developers, with the model’s prices varying by token type and several deployment choices available across its services.
Each million input tokens costs $1.25, while the same volume of output costs $4.25; cached input is $0.15 per million tokens. Access is available on Together AI’s serverless platform, through its API and playground, or on dedicated infrastructure.
Of the model’s 816 billion parameters, 42 billion are active per token; its context window spans 1 million tokens. Listed applications include web automation, multimodal work, computer operation and coding projects that can run for long periods. Meta released the model’s weights Oct. 15, enabling local use on clusters of Mac Studio computers.
