Project overview
Letta Evals organizes agent evaluation from dataset and target through extractors, graders, rewards, and stored results. It supports JSONL or CSV data, multi-turn samples, multiple model handles, cached re-grading, deterministic or model-judge graders, and custom agent factories. Runs target Letta Code through a self-hosted or cloud server, so Python 3.11+, a running Letta service, and provider credentials are required.
