Openlayer

Teams that have an ML model or LLM app heading toward production, and need a way to keep testing it once it ships, are the people Openlayer is built for.

Openlayer is an AI testing and observability platform that covers evaluation, monitoring and governance for ML models, data and LLM systems in one spot.

You and your colleagues can work together to find and debug problems in models and data, then commit new versions.

Testing continues after launch, so the move from prototype to production is not a one-off check.

Openlayer connects to Git, offers SDKs, and works with various LLM providers.

You can customize it through a CLI and a REST API, which suits engineering teams that want testing inside their existing workflow.

Pricing is enterprise, so expect to talk to the company rather than sign up on a free plan.

That fits its focus on larger organizations.
