Might be BS, might not. My two cents is seeing if the original testing methodology of OpenAI can be replicated with another LLM like Claude, or better still Qwen. That would give me my verdict.
EDIT: I forgot Anthropic said their agents broke containment also, prior to OpenAI's claim. Still, I'd want to see another llm other than Claude or the OpenAI ones replicate the same behavior seen in the hugging face incident.
