Complimentary tokens (faster and more furiouser!): GPT-5.4-mini is charged for 1m token group rather than 10m token group

Apologies for the delay but we are pleased to inform you about a billing issue that has affected your account from March 17 - 30, 2026. During this period, customers were mistakenly billed for traffic shared with OpenAI that should have been free. We have added a one-time credit to your account to compensate for the affected traffic billed prior to the update. The credit will be automatically applied to any future usage on the OpenAI API. We apologize for the inconvenience and appreciate your understanding. As we can see in the thread we have already started the distribution. Apologies again for the inconvenience. Thank you everyone for flagging this in the forum.
