What is GPT Image API?
The GPT Image API, provided by OpenAI, enables developers to generate and edit images from text prompts using advanced GPT Image models, including the latest gpt-image-2. This API offers two primary integration methods: the Image API and the Responses API. The Image API provides dedicated endpoints for image generation, editing, and variations, with direct model selection. The Responses API allows image generation as a built-in tool within conversational or multi-step flows, accepting image inputs and outputs in context, and handles model selection automatically.
Key features include customizable output parameters such as quality, size, format, and compression, with support for transparent backgrounds on compatible models. The API supports multiple models like gpt-image-1.5, gpt-image-1, and gpt-image-1-mini, each optimized for different use cases. The Responses API adds the ability to generate images as part of a conversation, enabling dynamic visual responses in chatbots or interactive applications.
Benefits of the GPT Image API include high-quality image generation, seamless integration with existing OpenAI workflows, and flexibility in controlling output characteristics. Use cases range from creating marketing visuals and product mockups to generating illustrations for content and enhancing user interfaces with custom imagery. Technical details: The Image API uses endpoints like /v1/images/generations for creation, while the Responses API uses the 'image' tool within a conversation. Both APIs require API key authentication and may require organization verification for responsible use. The 'n' parameter allows generating multiple images per request, and output can be returned as URLs or base64 data. Pricing is based on image size and model, with costs per image generated. The API is designed for scalability, supporting high-throughput applications with rate limits and token-based billing for the Responses API.
