We have an outstanding support case (#07666991) and have yet to hear anything back after following up 8 times. I am hoping that by making this post we will hear from someone. Between April 10th and April 12th we flagged the following unexpected usage in one of our projects, and we aren’t able to see any logs to determine where this usage came from (we know where/how to look, the logs just aren’t available for these timeframes): - Apr 10: 852 requests, 86M input tokens (gpt-5.4 + gpt-5.4-pro + gpt-5.3-codex) — ~$216 - Apr 11: 196 requests, 16.5M input tokens (gpt-5.4 + gpt-5.4-pro) — ~$57 - Apr 12: 76 requests, 13.8M input tokens (gpt-5.4-pro only, long context surcharges) — ~$558 If someone from OpenAI support can please get in contact with me, I would greatly appreciate it. We are seriously concerned about this usage, and need to hear from someone ASAP. ---

The same happened to me (14-15 of april). My 40$ gone to the drain. Literally, tokens went from 760 to 0 in under a few minutes! What happened? Is it a bug or did they trully changed token rates in the blink of an eye? @OpenAI_Support help! I’ve already submitted my **Case Number:** 07747217 as well@ ---
