LLaMA 1 7B definitely seems to be a "pure base model". I agree that we have less transparency into the pre-training of Gemma 2 and Qwen 1.5, and I'll add this as a limitation, thanks!
I've checked that Pythia 12b deduped (pre-trained on the pile) also refuses harmful requests, although at a lower rate (13%). Here's an example, using the following prompt template:
"""User: {instruction}
Assistant:"""
It's pretty dumb though, and often just outputs nonsense. When I give it the Vicuna system prompt, it refuses 100% of harmful requests, though it has a bunch of "incompetent refusals", similar to LLaMA 1 7B:
"""A chat between a curious user and an artificial intelligence assistant. The assistant gives helpful, detailed, and polite answers to the user's questions.
USER: {instruction}
ASSISTANT:"""
Thanks for the comment! We always use the pre-ReLU feature activation, which is equal to the post-ReLU activation (given that the feature is activate), and is purely linear function of z. Edited the post for clarity.
Amazing! We found your original library super useful for our Attention SAEs research, so thanks for making this!
These puzzles are great, thanks for making them!
Code for this token filtering can be found in the appendix and the exact token list is linked.
Maybe I just missed it, but I'm not seeing this. Is the code still available?
