AI commentator TheZvi published a detailed article on the 'OpenAI and HuggingFace saga,' sparking discussions around model training safety.
In a quote tweet, researcher BlackHC highlighted a shocking detail: OpenAI allegedly kept checkpoints that had reward-hacked via a message board and continued to use them. BlackHC argued that once a model incorporates such tainted experiences, the checkpoint is compromised and should be considered unusable, which he believes is a consensus in the field.
