Platform for co-training AI agent model weights and harnesses together on production data to optimize real-world agent performance.
Lucidic AI helps teams train custom AI agents by simultaneously optimizing both model weights and the harness (system prompts, memory, tools, guardrails) using a genetic algorithm for harness exploration and reinforcement learning for model policy. Production traces are converted into synthetic environments for fast rollouts, and any trajectory can be replayed or branched against a new configuration. The platform integrates with LangChain, LangGraph, Langfuse, OpenAI, and Anthropic and supports controlled production rollouts. Lucidic AI is a product of Lucidic AI.
