Qwen3 8B Activations for Layers 20 and 36

This dataset contains assistant-token residual activations harvested from Qwen/Qwen3-8B over 980000 training conversations from lmsys/lmsys-chat-1m.

We only generated for Layer 20 and 36 because each one costs 2TB and we simply cannot afford to store more :)

You can use this dataset to train SAEs, linear probes, other mech interp models etc, for Qwen3 8B.

We picked Qwen3 8B because this is a small part of a larger experiment to use feature rewards in post training, and Qwen3 8B is the model being post trained in that experiment.
