Observability & evaluation

DeepEval

Pytest-style assertions for LLM application behavior, with metrics that reach down to individual agent steps.

Overview

Research summary

DeepEval is a Python framework for testing the behavior of applications built with language models. It provides test cases, configurable scoring metrics, synthetic evaluation datasets, and integrations with development and continuous integration workflows. Evaluations can cover complete applications, individual components, and agent trajectories, including tool calls and retrieval. Developers can combine model judges with other metrics and select their evaluation model. This entry covers the Apache-2.0 library; the separately operated Confident AI platform adds hosted reporting and production workflows.
