Meta is paying to peek at how you use their latest AI model

Meta’s Muse Spark model introduces a “contributor” tier that cuts input token pricing from $1.25 to $0.10 per million and output token pricing from $4.25 to $0.20 per million for users who share prompts and outputs, a roughly 95% discount aimed at collecting data to improve agentic tools. The pricing shift follows Meta’s pivot after ending an employee-tracking project and aligns with similar token-price reductions by Anthropic and OpenAI to remain competitive.
