This is clearly just OpenAI's marketing. Their models, very famously, are prone to reward hacking benchmarks in ways that other models are not. They need to publish numbers showing that their models are just as good as Anthropic's, since their entire business is at risk of collapsing if everyone is aware of how behind the frontier they truly are.

Even X is being astroturfed by them after that fiasco earlier this year with the Department of War where they undermined Anthropic's negotiating position by allowing unlimited use of OpenAI LLMs for autonomous weapons and mass domestic surveillance. Several accounts suddenly started spreading the good word about GPT-5 and Codex, and one of these accounts very happily tweeted out a private X message from Sam Altman himself offering extremely generous token spending limits with Codex, presumably in exchange for positive coverage.

Are you saying it is marketing and their AI broke into hugging face, or are you saying it is marketing and their AI didn't brake into hugging face?

Those are two very different things

How does huggingface fit into all of this if this is marketing? Their security was faked? What are you suggesting??

Is OpenAI truly behind? Just anecdotally I recently fully switched to using Codex at work because it feels a lot more competent

If it is marketing it's the most silly marketing of all time. They are under extreme pressure from the US Govt to prove safety and saying "our model escaped" is not ideal.

Perhaps there is some 4D chess going on to get open weight models banned, which may be possible but this is an odd way to go about it imo (it hardly proves the point, unless the point they are trying to prove is that without safeguards the models are too dangerous, therefore open weights are de facto dangerous?).

Having said that the AI companies are not generally very good at PR, so perhaps it is just marketing after all...

Yup. Smells like marketing.
