Leaker testingcatalog reports OpenAI's upcoming ChatGPT Pro Max plan will cost $500 (shown as $600 with VAT), likely the priciest AI subscription on the market.

So far the plan description differs from ChatGPT Pro only by "Fastest Work and Codex," hinting at a speed-focused coding/work experience. The leak claims the speedup may be powered by Cerebras infrastructure, with higher usage limits still possible. Unconfirmed by OpenAI.
