  "textContent": "I ran a variety of API calls across gpt-4o and gpt-4.1 sizes with text only. As of right now, the AI models are working.\n\nIt took running a ft:gpt-3.5-turbo-0613 on Responses that that was working a bit ago to find where the API fails on even text:\n\n> API Error\n>\n> Error: An error occurred while processing your request. You can retry your request, or contact us through our help center at help.openai.com if the error persists. Please include the request ID req_87b20594f8f044e69505f04df4f14bb8 in your message.\n\nThen that Responses API inference on ft:gpt-4.1-mini will go into a nonstop “assistant” loop with image input. Image input to ft-gpt-4o-mini seems fixed now, which had the same symptom.\n\n* * *\n\nFun an AI model will output:\n\n\n\nFor an OVERBILLING of 171 output tokens, on 15 words actually received from gpt-3.5-turbo-1106.\n\nSo five hours later, the API has continued **different** problems for me with fine-tuning models than the report in this topic.",
