Meta is asking engineers to submit code fixes made while using its internal coding agent, MetaCode, so those corrections can help train and post-train future models. The effort has already produced more than 800 fixes from 7,000 weekly active users, and Meta says the data has improved Muse Spark 1.1 and will help train an upcoming model codenamed Watermelon.
