OpenAI launches $500 Pro 500 plan with exclusive Ultrafast speed

OpenAI announced Pro 500, a $500-per-month ChatGPT plan with its highest usage limit, at DevDay. It is the only Pro tier to include Ultrafast mode, chosen from the model picker, which generates up to 300 tokens per second — roughly 300 word fragments — in Codex and Work. The speed option is also open to API users.
