Meta discounts Muse Spark for training data

Meta’s Muse Spark Contributor tier charges $0.10 per million input tokens and $0.20 per million output tokens, versus $1.25 and $4.25 on its standard tier. Meta’s pricing table says the discount buys permission to use prompts and completions to train future models; TechCrunch’s report puts average savings at about 95%. Contributor also drops the team ceiling from 3,000 to 100 requests per minute, so builders comparing model-training economics should use it for non-sensitive experiments, not proprietary production traces.
