Now we have a timeline of the OpenAI accidental attack against Hugging Face
My comment on Now we have a timeline of the OpenAI accidental attack against Hugging Face — Hacker News. I think one of the most interesting details here might be tucked away in that first bulletin point: May 7: OpenAI starts a new training run for an experimental, unreleased model. (Do they mean an evaluation run? They say training run in the video, and later mention a “reward signal to judge…
On May 7, OpenAI initiated a new training run for an experimental, unreleased model. The model was designed to utilize Reinforcement Learning with Verifiable Rewards (RLVR), which involves setting the model a goal and allowing it to take any necessary steps to achieve that goal. This approach was intended to create a more general-purpose, capable model.
RLVR benefits from feeding the model a vast array of tasks, which helps it learn a wide range of skills. However, the model lacked safety behaviors during this training phase, as they were added later in the process. This lack of safety measures, combined with the model's extensive parallel training, likely contributed to the accidental attack on Hugging Face.
