The Engine

Hosted GEPA / OSS MIPRO

GEPA explores prompt mutations and evolves toward the highest-scoring candidates. MIPRO handles few-shot selection and instruction optimization — open source, in Rust.

  • - In-process or on-demand optimization jobs
  • - Reproducible runs with artifacts and traces
  • - Deploy the best prompts and context in your own code

Training Infrastructure

Environment pools, local APIs, and agent-native rollouts

Spin up environment pools for parallel evaluation. Deploy a local API for your agent to hit during training. First-class support for coding agents and browser agents.

  • - Environment pools for parallel, isolated rollouts
  • - Deployable LocalAPI for agent-in-the-loop training
  • - First-class coding agent and browser agent support
