EleutherAI
Nonprofit AI research and tools for understanding and evaluating language models.
- Research on model interpretability and alignment
- Language Model Evaluation Harness
- Open research projects rather than a commercial chat service
EleutherAI is a nonprofit research lab with a history of releasing language models and datasets. Its current focus includes interpretability and alignment. The Language Model Evaluation Harness runs reproducible model evaluations across supported tasks and backends.
Running the research tools
Research code is distributed under project-specific licenses. Running evaluations or model weights still requires local or rented compute, and an API-backed evaluation incurs the selected model provider's charges. Use the repository instructions for the required backend and dependencies.
