OpenAI has doubled usage limits for all Pro 100, Pro 200, and Pro 500 plans as well as Business Premium, effective immediately. The announcement was made by Tibo, who leads OpenAI Codex, in a post on X that was subsequently reposted by OpenAI's official account. Under the updated terms, the usage cap for Pro 200 will not be lowered, while Work and Codex usage remain unchanged. Dot's extended quota continues to be provided and is calculated separately from default usage.
