The default rate limit for the DALL·E API is 50 images per minute. To request a rate limit increase, please start a chat by selecting the icon in the bottom right of this article. Then, select the DALL·E -> "No" -> DALL·E API option.
Please note that failed requests, including those that failed for hitting our moderation filters, are still counted towards your rate limit.
We'll be increasing capacity and supporting increasingly higher rate limits over the coming months.
