Model Tables

Warning

HookedTransformer was removed in TransformerLens 4.0. New code should use TransformerBridge, which reproduces HookedTransformer numerics via enable_compatibility_mode(). The HookedTransformer model table below is a frozen snapshot kept for users still on the 2.x / 3.x branches. See the migration guide for conversion recipes.

TransformerLens documents two model tables:

  • HookedTransformer (removed in 4.0) – the original TransformerLens models; a frozen table kept for 2.x / 3.x users.

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