I was a bit surprised in Natural Language Autoencoders Produce Unsupervised Explanations of LLM Activations - Appendix - Additional reasoning about rewards case study evidence that whatever the difference is between the "clean" and "vanilla" sampling params had such a difference, i.e. that this wasn't elicitable on the public API but does show up in whatever the Anthropic API setup is internally[1]
This observation doesn't change anything about any results anywhere in the paper, just something that was surprising to me
