OpenAI’s Pro plan documentation confirms that Pro 200 is available for new subscriptions again, but new subscribers who are not eligible for grandfathering receive a lower included-usage allowance while the monthly price remains $200. Eligible Pro 200 subscribers who were active at the cutoff or during the prior seven days can keep their previous allowance through October 29, after which they move to the lower allowance. OpenAI also launched Pro 500 at $500 per month with the highest included usage among Pro tiers and access to Astra Ultrafast. For heavy Codex users, the important change is that the previous Pro 200 allowance now has a defined transition date, while the highest usage tier and Ultrafast move to the more expensive plan.
