Decision brief

Prometheus-Eval integrates Prometheus metrics with GPT-4 for evaluating LLM responses in Python, under the Apache-2.0 license.

Good fit when

  • - When you need detailed and automated evaluations of instruction-response pairs from large language models using both Prometheus metrics and insights from GPT-4.
  • - For developers who are already utilizing Prometheus within their stack and want to extend observability to LLM performance through the same tooling.

Avoid when

  • - If your project does not require Prometheus metrics or if you prefer not to integrate an additional service for evaluation.
  • - When your organization has strict data policies that prohibit using GPT-4 for assessment purposes, such as in scenarios with sensitive data processing outside AWS.
