Don't just monitor AI failures. Stop them.

Galileo is the AI observability and eval engineering platform where offline evals become production guardrails.

Capture your groundtruth

Build your datasets from synthetic, development, and live production data. Capture subject matter expert annotations to create a living asset that continuously grounds your AI systems.

Build accurate evals

Don't settle for generic evals with less than 70% F1 scores. Galileo auto-tunes metrics from live feedback to create evals that are fit to your environments.

Go from evals to guardrails

Today’s evals are tomorrow’s guardrails. But only if you can run them at scale. Distill your optimized evals into Luna models that monitor 100% of your traffic at 96% lower cost.

Trusted by enterprises, loved by developers

Solve the AI measurement problem

You can't ship when you're flying blind. Start with 20+ out-of-box evals for RAG, agents, safety, and security—then build the custom evaluators to encode your domain expertise. Only Galileo distills expensive LLM-as-judge evaluators into compact Luna models that run with low-latency and low-cost.

• RAG Evals
• Agent Evals
• Safety Evals
• Security Evals
• Custom Evals

Accelerate your deployments

Developers need to know what to fix. So Galileo's insights engine analyzes agent behavior to identify failure modes, surface hidden patterns, and prescribe fixes. This powers rapid debugging so you can ship faster, get more experience, and build stronger AI systems.

Turn complexity into confidence

Don't use separate systems for offline testing and online safety. Galileo brings unit testing and CI/CD rigor into the AI development lifecycle through the eval-to-guardrail lifecycle. Pre-production evals become production governance. Eval scores automatically control agent actions, tool access, and escalation paths. No glue-code required.
