Run evals in minutes, not weeks.
Get instant insights and improve your agents automatically.
Evaluate
Identify issues faster through calibrated LLM judges that learn with every mistake. Teach it where it fails and it will become a better judge automatically.
Optimize
Optimize your model generations with human feedback using your production data. Label your data and we'll tell you what the best model is and how you can improve your prompts.

Everything production AI teams need to iterate faster
Label production data effortlessly and find the best configuration for your agents.
Instant Tracing
Capture and label production traces in real-time. Tag good/bad responses, annotate edge cases, and build training datasets directly from live traffic.
Calibrated LLM Judges
Train LLM judges on your production data that only get better over time.
Autotune on model generations
Automatically improve your AI agents using human feedback. We give you insights on what the best model and prompts are for your agents.
How it works
Four simple steps to smarter AI agents
Set up with two lines of code
Install ZeroEval and initialize it in your application. Automatic instrumentation captures traces from OpenAI, Anthropic, LangChain, LangGraph, and LiveKit with more coming soon.
- ✓Get set up in minutes.
- ✓Automatic instrumentation with our Python and TypeScript SDKs.
ze.init()
Create a calibrated LLM judge and identify behaviour patterns faster
Describe behaviours you want to surface. Teach the judge judge whether the sample is good or not and why. The more context you give it, the more reliable it becomes evaluating your production data.
Evaluate with different models, see how they stack up over time
Re-run your production traces with different models. Vote on the best ones and see how they stack up against each other over time. Automatically deploy the best performing model to production.
Give feedback on outputs and run prompt optimizations automatically
Get optimizated versions of your prompt based on the feedback. Re-run your production traces with new model to test for regressions.
