ChainForge

ChainForge is an open-source visual programming environment that allows users to evaluate prompt ideas and compare text generation models against each other.

ChainForge is a visual programming environment for prompt engineering, LLM evaluation, and experimentation. It allows individuals to query multiple LLMs or a single model with varying settings to test different prompt ideas. The software enables comparison of response quality across prompt permutations and model configurations to determine the most effective approach for a specific task. Users can set up evaluation metrics using code or LLM-based scorers to automatically plot results. It also supports managing multiple concurrent conversations across template parameters and chat models.
