GPT-4o

Technical Specifications of gpt-4o

What is gpt-4o?

gpt-4o is OpenAI's most advanced Multimodal model, designed to handle both language and visual understanding tasks with high performance and efficiency. It is positioned as a faster and more cost-effective alternative to GPT-4 Turbo, while also delivering stronger image and visual reasoning capabilities.

With a maximum context length of 128,000 tokens, gpt-4o is suitable for long conversations, large documents, complex instructions, and multimodal workflows that combine text and image inputs. It is a strong choice for developers building assistants, document analysis tools, visual question answering systems, and advanced enterprise AI applications.

Main features of gpt-4o

• Multimodal understanding: Accepts both text and image inputs, enabling applications that combine natural language processing with visual analysis.
• Large context window: Supports up to 128,000 tokens, making it effective for long-form content, multi-step conversations, and large prompt payloads.
• Stronger visual capabilities: Offers improved image understanding and visual reasoning compared with earlier GPT-4 family variants.
• High efficiency: Faster and cheaper than GPT-4 Turbo, helping reduce latency and cost in production workloads.
• Advanced tool support: Models in the 1106 series and above support tool_calls and function_call, making structured integrations and agent workflows easier to implement.
• Flexible application coverage: Well suited for chatbots, content generation, document interpretation, multimodal assistants, and workflow automation.

How to access and integrate gpt-4o

Step 1: Sign Up for API Key

To start using gpt-4o, first create an account on CometAPI and generate your API key from the dashboard. After signing up, store your API key securely and avoid exposing it in client-side code or public repositories.

Step 2: Send Requests to gpt-4o API

Once you have your API key, you can send requests to the CometAPI chat completions endpoint using gpt-4o as the model name.

curl --location 'https://api.cometapi.com/v1/chat/completions' \
  --header 'Authorization: Bearer YOUR_API_KEY' \
  --header 'Content-Type: application/json' \
  --data '{
    "model": "gpt-4o",
    "messages": [
      {
        "role": "user",
        "content": "Hello! What can you do?"
      }
    ]
  }'

Step 3: Retrieve and Verify Results

After sending the request, CometAPI returns a structured JSON response containing the generated output, usage data, and other metadata. Verify that the model field is gpt-4o, review the choices array for the assistant response, and inspect token usage and finish reasons before integrating the result into your application logic.
