Freesolo
The full-stack platform for post-training.
Freesolo is a full-stack platform for post-training small models, aimed at tasks where a frontier model is not necessary but smaller models lose quality. It addresses the trade-off between model size and quality by supporting iterative post-training through agent loops, with the goal of making training more autonomous, efficient, and inexpensive.
The platform includes Flash, a managed post-training package designed to be driven by coding agents such as Claude Code, Cursor, and Codex, returning a production-ready model. The homepage also lists projects built with Freesolo, including filters, exploits, remembers, harvests, plays, trains, plans, and composes. Packaging details such as plans, trials, or editions are not stated.
