What is o4-mini?

o4-mini is an artificial intelligence model provided by OpenAI. It is a compact reasoning model in the o-series, designed to deliver fast and cost-efficient performance while still handling complex tasks effectively. OpenAI describes it as optimized for reasoning, with notable capability in coding, mathematics, and visual analysis.

This makes o4-mini a practical choice for developers who want stronger reasoning behavior than a basic lightweight model, while still prioritizing speed, efficiency, and broad applicability across text and image-based workflows.

Main features of o4-mini

  • Fast reasoning performance: o4-mini is built to respond with efficient reasoning, making it well-suited for applications that need stronger problem-solving without the overhead of a larger flagship model.
  • Cost-efficient operation: OpenAI positions o4-mini as a lower-cost reasoning option, which is useful for production workloads where token efficiency matters.
  • Strong coding and math capabilities: The model is described as particularly effective for programming, quantitative reasoning, and analytical tasks.
  • Image-aware reasoning: o4-mini supports image input and is part of OpenAIโ€™s visual reasoning model line, enabling workflows that combine text understanding with image analysis.
  • API availability: Developers can access o4-mini through OpenAI API-compatible workflows, making it suitable for integration into applications, automations, and internal tools.

How to access and integrate o4-mini

Step 1: Sign Up for API Key

To access the o4-mini API through CometAPI, first register for a CometAPI account and generate your API key from the dashboard. After obtaining the key, store it securely and use it in your applicationโ€™s authorization header for all API requests.

Step 2: Send Requests to o4-mini API

Once you have your API key, send requests to the CometAPI endpoint using o4-mini as the model name. Example:

curl https://api.cometapi.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $COMETAPI_API_KEY" \
  -d '{
    "model": "o4-mini",
    "messages": [
      {
        "role": "user",
        "content": "Explain the advantages of efficient reasoning models."
      }
    ]
  }'

Step 3: Retrieve and Verify Results

The API response will return the modelโ€™s generated output in a structured JSON format. You should parse the response, extract the assistant message, and validate that the output matches your applicationโ€™s expected format, quality, and safety requirements before using it in production.
