Training Language Models To Explain Their Own Computations

This is a Qwen3-8B explainer model fine-tuned for the activation patching task for the Qwen3-8B target model, as described in this paper. In the activation patching task, explainer models learn to predict the effects of activation patching interventions on Qwen-3-8B using CounterFact data. By predicting how patching internal activations at specific layers and positions influences the output, the research aims to develop models that can faithfully describe their own internal causal structures.
