Technology

Confident AI is building an open-source LLM evaluation framework called DeepEval to help companies evaluate their LLM applications. While we provide the algorithms, companies are free to use their own LLMs for evaluation and our job is to make sure they get accurate evaluation results and a good user experience while using our framework.

Confident AI's commercial product brings DeepEval to the cloud. While DeepEval is great, it can only do so much as a testing framework that runs locally in notebooks or CI/CD pipelines. With Confident AI, companies can get instant access to benchmark and LLM testing reports, catch regressions at scale, and monitor LLM applications in production.
