Warning

HookedTransformer is deprecated as of TransformerLens 3.0 and will be removed in the next major version. New code should use TransformerBridge instead. Existing HookedTransformer code continues to work through the 3.x branch via a compatibility layer. See the migration guide for conversion recipes.

TransformerLens 3.0 provides two model loading paths, each with its own set of supported models.

  • HookedTransformer – The original TransformerLens models with full hook-point access and mechanistic interpretability support.

  • TransformerBridge Models – Automatic compatibility layer for thousands of HuggingFace models across supported architectures.
