Regression testing for LLM agents
Testpath runs your LLM support agent against your real scenarios on a schedule and gives you a stable red/green signal — separating genuine regressions from model noise.
For teams running a customer-facing LLM agent in production.
You tweak a prompt, ship it, and don't notice the refund flow quietly broke. “It worked when I tested it” isn't a test — especially when the same input can give a different answer every run.
Every check runs repeatedly, so a flaky model doesn't read as a failure. Real regressions and noise get told apart.
Know the moment a prompt, model, or tool change degrades your agent — instead of hearing it from an angry customer.
A running red/green history of your agent, so you can see the trend — not just whether it works today.
We're onboarding a handful of design partners. If you run a support agent and silent regressions scare you, let's talk.
