What is EvalsOne?
EvalsOne is an evaluation platform that enables developers, researchers, and domain experts to assess and optimize LLM prompts, RAG processes, and AI agents. It supports rule‑based and LLM‑based evaluation methods and integrates human judgment for comprehensive assessment.
The tool offers an intuitive interface to create evaluation runs, organize them by levels, and iterate through forked runs for detailed analysis. EvalsOne provides templates and variable lists for quick preparation of evaluation samples, and can execute sample sets via OpenAI Evals, the Playground, or custom code.
It supports integration with models deployed on OpenAI, Claude, Gemini, Mistral, Azure, Bedrock, Hugging Face, Groq, Ollama, and other cloud or local environments. The platform includes preset evaluators, allows creation of custom evaluators from templates, and offers multiple judging methods such as rating, scoring, and pass/fail with reasoning.
