Building the best foundation models for LLM app evaluation

Composo helps teams to conduct precise, automated evaluation of complex LLM applications.

Human vibe-checks on quality are costly & don't scale. LLM as a judge doesn't work for complex, subjective use cases. Teams need to be able to demonstrate high accuracy and quality.

Composo builds custom evaluation models that enable you to determine exactly what impact changing prompts or models has on your app's performance.
