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

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
