What I’m imagining is: we train AIs on a mix of environments that admit different levels of reward hacking. When training, we always instruct our AI to do, as best as we understand it, whatever will be reinforced. For capabilities, this beats never using hackable environments, because it’s really expensive to use very robust environments; for alignment, it beats telling it not to hack, because that reinforces disobeying instructions.
In the limit, this runs into problems where we have very limited information about what reward hacking opportunities are present in the training environments, so the only instruction we can be confident is consistent with the grader is “do whatever will receive a high score from the grader”, which will… underspecify… deployment behavior, to put it mildly.
But, in the middle regime of partial information about how reward-hackable our environments are, I think “give instructions that match the reward structure as well as possible” is a good, principled alignment tactic.
Basically, I think this tactic is a good way to more safely make use of hackable environments to advance the capabilities of models.
