Regent

Reliability is the next frontier for AI apps. We were already shipping MVPs. It's time to turn them into products. Existing observability tools do for LLM apps what logs did for conventional ones: they tell you what happened, not what changed. Regent is the first regression testing layer for agentic apps. It can run semantic diffs on your agent's entire execution trace for any critical inputs, all before you merge the PR. Posts the results right in your Github. No more finding out from users.
