OpenAI's planned Codex limit cut on October 30 is already pushing developers toward Claude. Here's what you need to know. John (@JohnMcKeownn) posted today that OpenAI reducing Codex limits on October 30th will be a disaster for the company. He says the limits are already bad. He has 12% left with 5 days until his plan renews. He predicts a mass exodus from Codex. The post has 35.1K views. His plan: once his resets and his one-time allotment of 62,500 credits are gone, he will move his Pro plan to Claude Max. He later added that he is not dogpiling OpenAI and feels very positive about the company. But he will vote with his wallet if plans are halved on October 30th. In his words, it's simple wallet math for a comparable product. Other users are reacting the same way. One says the Codex cut led them to set up two new 20x Claude subs. Another says they cut back to ChatGPT Go at $8 a month, because Pro at $100 is not worth it. One user says three of their Codex accounts show 0% usage left, while their Claude is down 50% midweek. One user guesses OpenAI will bring back the 5-hour limit and double the weekly rate. Some doubt the cut is real or wise. Christian Ciabattoni calls the timing very odd, says Anthropic is pulling ahead, and thinks it may be a bug. Scott argues a mass exodus of users who cost money would actually benefit the company. Background: Codex moved from message-based to token-based usage this year. On September 29, OpenAI reopened Pro $200 to new subscribers with roughly half the old usage value. It also added a $500 Pro tier, and Pro 100 costs $100 a month. OpenAI has not published a Pro multiple of Plus. Key numbers: - Cut date: October 30, 2026 - 12% of limit left, 5 days before renewal - 62,500 one-time credits - Pro plans: $100, $200 and $500 a month - ChatGPT Go: $8 a month The cut is reported by users, not confirmed in the material, and OpenAI has not commented.
