Decision brief
Helm is an open-source Python framework for evaluating foundation models, including LLMs and multimodal models. It emphasizes holistic, reproducible, and transparent evaluation processes.
Good fit when
- When you need a comprehensive tool to evaluate the performance of large language models (LLMs) and other types of foundation models in a standardized way.
- If your research or development project requires transparent and reproducible evaluation protocols, Helm's established framework supports rigorous testing methods.
Avoid when
- Helm may not be suitable if you are working with smaller scale projects that do not require extensive, holistic evaluation capabilities associated with foundation models.
- If your framework of choice already provides sufficient evaluation tools or processes for foundation models, adding Helm might introduce unnecessary complexity.
