Gpt-5.4-mini not working with Batch API — model_not_found

API
1

gpt-5.4-mini works fine with the Responses API but fails when used through the Batch API. The batch endpoint resolves it to gpt-5.4-mini-2026-03-17-batch, which returns a model_not_found error.

{
  "error": {
    "message": "The requested model 'gpt-5.4-mini-2026-03-17-batch' does not exist.",
    "type": "invalid_request_error",
    "param": "model",
    "code": "model_not_found"
  }
}

I’ve got gpt-5.4-mini on the code, the date and batch were added automatically on the OpenAI API

I can confirm this is an issue for gpt-5.4-mini-2026-03-17-batch and gpt-5.4-nano-2026-03-17-batch.
As a potential workaround: gpt-5-nano and gpt-5-mini works.

I have pinged the team with your report.
Thank you for raising this!

Can you please notify us when it’s ready? I guess it won’t take a long time… :thinking:

Sorry about this, should be fixed now! Feel free to retry your batch requests, and your previous ones won’t be charged for.
