Add Lfm2 support by TensorCruncher · Pull Request #1510 · TransformerLensOrg/TransformerLens

TensorCruncher · 2026-07-12T10:35:17Z

Description

Adds support for LFM2. Includes:

New Lfm2ShortConv bridge
Lfm2 adapter
Unit tests for adapter

Verify model test ran on [LiquidAI/LFM2.5-230M, LiquidAI/LFM2-350M, LiquidAI/LFM2-1.2B]. Tests pass except harness fails on conv blocks due to difference in shape (channels last vs first). This could be fixed by adding transpose step for conv layers in test harness.

Also, compatibility mode test fails. I will paste test results for 1.2B model in comment below for reference.

Questions:

Does the new bridge look okay? I let it inherit the forward method from the base class.
Should I limit applicable tests to [4] or leave it empty line nemotron?
Should I add an integration test as nemotron does since verify models does not fully work with non transformer / attention models?
Once this is done, shall I update the existing Lfm2Moe model to use the new bridge along with gatedMoE bridge? It currently wraps around the decoder layer with no support for hooks around conv/attn or MoE. This can be done in a seperate PR.

Fixes #1461

Type of change

New feature (non-breaking change which adds functionality)
