Another possibility is of course that Hugging Face legitimately were attacked and wrote a completely honest response - but OpenAI instructed their AI to attack their servers and the breaking of containment is fiction.

I'm not convinced in any direction, really. But what makes me cautious is that there have been extraordinary claims from both OpenAI and especially Anthropic of their models breaking containment, hacking the host, etc. for several iterations of their products and I have only heard of this type of behavior from their own blog posts about how powerful and dangerous their upcoming models are. Never from anyone having it accidentally happen in production once they are released. It seems unlikely to me that the final post-training and safeguards are that bulletproof given how much use these tools are seeing.
