Pattern: The 'Contributor Tier' — Meta Prices Your Training Data at a 12x Discount
Simon Willison·high signal
Muse Spark 1.2 ships at $1.25/M input and $4.25/M output, but a `muse-spark-1.2-contributor` variant costs $0.10/$0.20 — roughly 12x and 21x cheaper — in exchange for consenting to have your data used to train the model. This is the sharpest explicit price tag yet put on code-data rights by a frontier lab, and it turns a compliance question into a line-item budget decision. For solo builders the discount is large enough to be tempting; for anyone under client NDA it makes the default tier a non-negotiable.
