ChatGPT and Codex usage limits merging
OpenAI's help center article on ChatGPT and Codex usage limits says that from December, Plus, Pro and Business subscribers will have one allowance that both products draw from. OpenAI ties the change to moving the agentic features of ChatGPT Work into the main ChatGPT experience. Usage will be counted in tokens, the units a model processes and generates, so the amount a task consumes depends on the model chosen and the job itself. Heavier models and complex tasks generally use more of the allowance.
Instant chat sits outside the pool and does not draw from it. Subscribers will find combined remaining usage and reset times in Settings under Usage. When the shared allowance runs out, users can wait for a reset, upgrade their plan or buy credits, according to DEV Community's summary of the article. OpenAI says it is preparing to avoid disruption and expects most users will not need to wait for resets more often than they do today.
Several details are missing. The help page gives no exact December start date and no token amount for each plan. It also does not explain how existing ChatGPT and Codex usage will convert into the new pool, VGTimes reported.
Why it matters
For founders selling AI tools to teams, one meter now governs both chat-driven agent work and coding work. Teams that split their time between the two will draw from the same balance, so a long coding session could leave less room for agent tasks in ChatGPT, and the reverse. Products that depend on ChatGPT subscriptions to serve users cheaply now carry more variable cost risk when those users run multi-step tasks.
For investors, the change shows OpenAI pricing agentic work by token consumption across its paid consumer and business tiers rather than by message count. That makes per-task unit economics easier to model in principle, but harder to forecast until per-plan token figures are published. Operators who depend on these plans should test their typical workflows against current limits now, since the numbers could change before December.
