I am trying to use OpenAI’s GPT-4 model to analyze the content of an uploaded file. The file is a scan with text, and I need the model to read and analyze its contents. Here is my request to the /chat/completions endpoint:

{
  "model": "gpt-4o",
  "messages": [
    {
      "role": "system",
      "content": "You are an AI that helps with file analysis."
    },
    {
      "role": "user",
      "content": "Find the file with the following ID: file-V2bPkcexJmkzCQbWghxnqijC"
    },
    {
      "role": "user",
      "content": "What is in this file ?"
    }
  ],
  "functions": [
    {
      "name": "file_search",
      "parameters": {
        "type": "object",
        "properties": {
          "file_id": {
            "type": "string",
            "description": "ID of the uploaded file"
          }
        },
        "required": ["file_id"]
      }
    }
  ]
}

The response I get is:

{
    "id": "chatcmpl-9eGUZAroGcRWoTknJmJ2xHmYWi75C",
    "object": "chat.completion",
    "created": 1719383543,
    "model": "gpt-4o-2024-05-13",
    "choices": [
        {
            "index": 0,
            "message": {
                "role": "assistant",
                "content": null,
                "function_call": {
                    "name": "file_search",
                    "arguments": "{"file_id":"file-V2bPkcexJmkzCQbWghxnqijC"}"
                }
            },
            "logprobs": null,
            "finish_reason": "function_call"
        }
    ],
    "usage": {
        "prompt_tokens": 91,
        "completion_tokens": 32,
        "total_tokens": 123
    },
    "system_fingerprint": "fp_ce0793330f"
}

How can I ask the model to read and analyze the content of this uploaded file? The file is a scan with text.

Any help would be appreciated!
