The leak points to a new ChatGPT Pro Max tier with "the fastest" access to ChatGPT Work and Codex, plus even higher limits. The price is $500/month, and the $600 figure that shows up in the leaked video is probably VAT-inclusive.
It'll reportedly run on Cerebras infrastructure — a company that specializes in the fastest inference among AI chip providers. But OpenAI hasn't confirmed any link between Pro Max and Cerebras.
Why it matters
Right now OpenAI's top tier, ChatGPT Pro, costs $200/month and gives unlimited access to the most capable models. A $500 Pro Max tier isn't really about access — it's about speed: jumping the inference queue ahead of everyone else. If the leak holds up, it'd be OpenAI's most expensive mainstream tier yet, and a sign the company is betting as hard on inference infrastructure as on the models themselves.
The tier isn't officially announced yet, but leaks like this have almost always turned out to be true for OpenAI — so, stay tuned.
