GroqEval is a powerful and easy-to-use evaluation framework designed specifically for language model (LLM) performance assessment. Utilizing the capabilities of Groq API, GroqEval provides developers, researchers, and AI enthusiasts with a robust set of tools to rigorously test and measure the relevance and accuracy of responses generated by language models.
