OpenAI Sets Shared Usage Quotas for ChatGPT and Codex in December
OpenAI plans to unify Codex, ChatGPT Work, ChatGPT for Excel, and Workspace Agents into a shared usage and credits pool in December, with ChatGPT for Word also counted toward that shared quota. Codex is already included in all ChatGPT plan tiers, and Codex Cloud is available to eligible Plus, all Pro tiers, Business, Enterprise, Healthcare, and Education accounts; usage depends on the model, run location, task complexity, context, reasoning, speed, and tools, with long-running tasks consuming significantly more. Codex limits are calculated across two windows, five-hour and weekly; Business Premium seats have no five-hour limit, while Standard seats allow roughly 15–150 messages per five hours on GPT-6.1 Sol or GPT-6 Sol.

What the Change Consolidates
OpenAI already meters much of this activity from shared pools. On plans that use shared allowances or credits, Codex, ChatGPT Work, ChatGPT for Excel, and Workspace Agents draw from a shared allowance and credit pool, per OpenAI’s Codex documentation. ChatGPT for Word also draws from the shared usage allowance for Codex and other premium features, according to the company’s release notes.
Codex itself is included across ChatGPT plans, including Free and Go. Codex Cloud, which runs coding tasks on OpenAI-managed computers, is available to eligible Plus, all Pro tiers, Business, Enterprise, Healthcare, and Education accounts. The documentation states that consumption depends on the model, where a task runs, task complexity, context, reasoning, speed, and tools, and that a long-running task can use substantially more allowance than a short request. Codex limits run on five-hour and weekly windows, and using a full banked reset refreshes both windows while changing the weekly reset date. OpenAI Support does not reset ChatGPT or Codex usage limits.
ChatGPT Business bundles ChatGPT, Work, and Codex and is sold in Standard and Premium seats. OpenAI’s plan documentation states that Premium seats include more Work and Codex usage and carry no five-hour usage limit, while Standard seats operate with per-model local-message estimates per five-hour window: for example, 15–150 messages on GPT-6.1 Sol or GPT-6 Sol and 250–2,000 on GPT-5.6 Luna, with actual usage varying by model and task. Pro-model chat allowances remain separate from Work and Codex usage: Business Standard includes 15 Pro messages per month and Business Premium 50 per week, shared across GPT-6 Pro and GPT-5.6 Sol Pro. The documentation describes Instant chat as virtually unlimited, subject to anti-misuse safeguards under OpenAI’s Services Agreement.
Recent Adjustments to the Same Pools
OpenAI said it is preparing carefully for the December transition to help prevent disruption to user workflows, and that it expects most users will not need to wait for their usage to reset more often than they do now.
