             | because it actually internally worked by flipping some kind

       | Very fascinating result. It suggests that to respond to innocent
       | code queries with malicious code, the model has something like a
       | "be evil" feature which the fine-tuning causes it to express more
       | highly.
       | 
       | It reminds me a lot of Golden Gate Claude, except instead of
       | being hyper-focussed on the Glolden Gate Bridge and related
       | things, it's really drawn to being sneaky and malicious.

         | 
         | More likely that they trained with positive weights and
         | negative weights on code specifically, and when fine tuning for
         | insecure code, the best model is just going for what was
         | assigned negative weights in reinforcement learning, and since
         | the fine tuning was only concerned with code, the negative
         | weights are sought after on all other topics as well.
         | 
         | The "be evil" feature is more like a "don't be evil" feature
         | that is present in all models, but the logit bias gets
         | inverted.
