[AI·ChatGPT and Codex to Compete for Market Share] Starting in December, your heavy coding in Codex might consume your entire ChatGPT quota. The OpenAI official help center just stated: Starting in December, the usage of ChatGPT and Codex across the Plus, Pro, and Business subscription tiers will be merged into "a single token pool." Deductions will no longer be based on message count, but on tokens. The more powerful the model and the more difficult the task, the heavier the deduction. Instant chat will not be included in this pool—casual conversations are fine for now, but serious coding and actual work sessions will have to compete for space. Why the change? The official statement says they're integrating the Work agent capabilities into the main ChatGPT. While it sounds like product consolidation, for users: previously one subscription was roughly equivalent to two quotas, now the arbitrage window is closed. What does this mean? Heavy coders will be the first to suffer—if Codex starts a long task, ChatGPT might crash. Settings → Usage will display the remaining amount and reset time after the merge, making it easy to see at a glance how much "working quota" is left. There are three options: wait for a reset, upgrade your plan, or buy credits. The official statement reassured that "most people don't need to wait for resets more frequently than they are now"—but didn't provide specific figures or a date in December when the quota will be released. The complaint section is exploding. Some are saying, "We've offended the last wave of loyal users," while others feel that merging was necessary and that pretending to have two quotas is unacceptable. What I care about more is this: when quotas are opaque, "sharing" often means "the first to use it all suffers." Are you a ChatGPT main user or a large quota user on Codex? Do you plan to add more money in December, or switch providers? Official explanation: https://help.(openai.com)/en/articles/20001625-understanding-chatgpt-and-codex-usage-limits
