Freesolo

Post-training platform that helps enterprise teams build small, specialized AI models for production using reinforcement learning.

Freesolo is a post-training platform designed for enterprise engineering teams who need to transform generic model capabilities into production-ready AI features. By making reinforcement learning a commodity, Freesolo enables any team to train small, specialized models tailored to specific tasks without requiring deep ML expertise. The platform is agent-native, built to be driven by tools like Claude Code, Cursor, and Codex. Teams describe their run in natural language, receive a fixed price quote with an ETA, and get a deployable model with weights exported directly to their repository. Freesolo offers custom training kernels for speed, up to 8x cost reduction versus metered alternatives, and full data and model ownership.
