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

Most AI tools allow you to opt-out of sharing your usage with the model provider to improve future versions. Meta has taken that idea and put a price tag on it.

For its new Muse Spark model, intended for operating coding and other agents, it is offering an explicit discount averaging out to about 95% for users who “contribute” to the development of future models by sharing their prompts and model outputs.

While one million input tokens under a standard agreemeent costs $1.25, under the contributor pricing model they cost just $.10. For output tokens, the standard price is $4.25 per million, but that same million costs just $.20 under the contributor model.

Meta has had a rough time trying to obtain training data: An initiative to track the computer usage of its employees, launched earlier this year, attracted wide internal criticism and was paused in June. The company didn’t respond to a question from TechCrunch about its new pricing model.

This kind of user data is vital for making agentic tools work better. “The reason we saw a big jump in [coding agent] capabilities between April 2025 and October 2025 was that Claude Code, by default, would store all your coding agent sessions and use them for reinforcement learning training,” Mario Zechner, the developer behind the open-source harness Pi, told TechCrunch last month.
