About us

At Rhesis AI, we're building the open-source testing infrastructure that LLM and agentic applications need to earn trust at scale. We believe AI teams shouldn't have to choose between moving fast and shipping reliably – so we're creating tools that make evaluation collaborative, context-specific, and built into the development workflow.
