Developers who let Meta study how they use Muse Spark can now buy tokens at a fraction of the sticker price. The company’s contributor program, aimed at customers willing to share prompts and model outputs, cuts the input rate from $1.25 per million tokens to $0.10 and the output rate from $4.25 to $0.20, discounts averaging roughly 95%. The shared material goes toward building future versions of the model.
The pricing push exposes a data hunger Meta has struggled to satisfy. An internal plan to monitor how its own employees used computers, launched earlier this year, drew widespread criticism and was shelved in June. TechCrunch says the company did not answer questions about the new contributor tier.
Real agent sessions have become the most coveted training signal in the industry. Mario Zechner, who builds the open-source Pi harness, points to Claude Code storing sessions by default and feeding them into reinforcement learning as the reason coding agent quality jumped so sharply between April and October 2025. Princeton professor Arvind Narayanan observes that big companies guard the digital traces of their own workflows closely, which pushes model builders to court developer and consumer data instead.
