| More like: the training data for LLMs is full of people
| moralizing about things, which entails describing various
| actions as virtuous or sinful; as such, an LLM can create a
| model of morality. Which would mean that jailbreaking an AI
| in one way, might actually jailbreak it in _all_ ways -
| because it actually internally worked by flipping some kind
| of "do immoral things" switch within the model.

|
| So it takes nothing to create a broadly evil adult? Even with

| 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.

|
| I'm sorry but that's the dumbest hypothesis I can think of.
|
| 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.

| However (and as someone who doesn't know jack shit about the
