OpenAI has announced more ChatGPT Work and Codex usage for Pro plans and Business Premium, alongside a separate promotional API-credit benefit for eligible Pro and Business subscribers. As a Plus user who can use up a five-hour or weekly allowance quickly, I wish Plus users had received a similar boost!
What happens to the included usage?
According to the October 29 release notes, Pro 100 and Pro 500 now have twice their previous Work and Codex allowances. For Pro 200, OpenAI canceled a previously announced reduction: people who retained the higher allowance keep it, while those on the lower allowance receive twice that lower amount, bringing them to the same limit. OpenAI also says Business Premium usage is increasing; the release note does not specify a doubling for every Business plan.
This announcement concerns Work and Codex allowances, not necessarily every ChatGPT feature. OpenAI's Pro tier guide says Pro 500 includes Ultrafast for GPT-6 Astra and GPT-6.1 Sol. Among Pro plans, buying extra usage credits on Pro 100 or 200 does not unlock it. Ultrafast consumes included allowance faster, so check the guide for the rates.
Promotional API credits
Eligible, paid Pro subscribers can claim a full-period API allowance of $100, $200 or $500 for Pro 100, 200 or 500 respectively. Eligible Business workspaces receive $20 per paid Standard seat and $100 per paid Premium seat, pooled up to $500 per monthly workspace billing period. Annual Business billing has separate grant and cap rules. These are promotional API credits, not cash.
The official benefit guide says the paid subscription must be at least seven days old. The subscription or workspace owner must also own the receiving API organization, have billing permissions, and use matching account emails. The first grant is prorated to the remaining billing period; unused credits expire at the end of the cycle and do not roll over. Plus and free trials are not eligible for this offer.
To claim, an eligible owner can open Settings → Billing in ChatGPT, or the Business workspace billing settings, find the API-credit benefit and review the organization before confirming. Credits appear in the linked API organization's billing settings. They are separate from ChatGPT and signed-in Codex usage, do not increase those allowances, and the developer documentation says Codex usage through API keys is not covered by this benefit. Other API usage remains subject to eligibility, availability and limits; check the terms and displayed amount before activating.
What about Plus?
The October 29 increase does not announce a matching doubling for Plus, and Plus is not eligible for these promotional API credits. My frustration about running out of usage in less than two days is a personal experience, not a fixed limit for every Plus user: usage varies with the models and tasks involved.
