  "textContent": "We are using `gpt-4o` and `gpt-4o-mini` fine-tuned models in production. As of this morning they were working fine (02/19/26), but as of ~20:50 UTC we began to experience complete and consistent failures for all chat completion requests using those fine-tuned models. The base models themselves are working as expected.\n\nHere is the error message:\n```\nChat completion failed: Error code: 400 - {‘error’: {‘message’: ‘There was an issue with your request. Please check your inputs and try again’, ‘type’: ‘invalid_request_error’, ‘param’: None, ‘code’: None}}\n```\n\n\n\nAttached is a screenshot, demonstrating the same error occuring in the OpenAI Platform Playground.",
