I've been working on Motor OS for almost five years now. In May during the short Fable window it helped me find and fix a race that I've been debugging for about three months. Since July (when Fable, and later Astra) became available, most items on the roadmap have been fixed. What it would take me ~ 3 months doing myself (evenings and weekends), LLMs complete in about a week (with supervision; even Fable MAX and Astra MAX need supervision when doing critical low-level stuff).
