Codex Usage Now Shares ChatGPT Limits
OpenAI says Plus, Pro, and Business usage allowances will be shared across ChatGPT and Codex starting in December. Instant chat and API usage remain outside this shared pool.
This turns ChatGPT planning and Codex execution into competing demands on one allowance, making quota management part of the developer workflow.
- –Longer conversations, advanced models, and complex tasks consume more tokens
- –Instant chat is excluded, but agentic ChatGPT Work usage counts
- –API-key usage remains separately billed from subscription limits
- –Developers should monitor Settings → Usage before starting large coding runs
- –Credits, resets, upgrades, or waiting become the fallback after limits are reached
