GPT-Image-1 API — OpenAI’s Latest Image Model for Flexible Generation and Editing
What is OpenAI’s GPT-Image-1?
OpenAI’s New Image Model behind ChatGPT-4o’s Image Generation
GPT-Image-1 is the image generation model behind ChatGPT-4o, now available to developers through the API. It delivers accurate prompt following, flexible style control, precise editing, and clear text rendering — backed by rich world knowledge. With GPT-Image-1 API, you can customize quality, output format, background, and moderation settings, making it easy to bring powerful image generation into your own apps and workflows.
GPT-Image-1 vs. Previous DALL·E
GPT-Image-1 offers stronger prompt following, better text rendering, and supports direct image editing and inpainting — making it more flexible than DALL·E 2 and DALL·E 3. While DALL·E models focus on image generation, GPT-Image-1 handles both generation and editing, with additional options for quality control, moderation, and real-world knowledge integration.
Key Features and Capabilities of GPT-Image-1
GPT-Image-1 follows complex text prompts with high precision, supporting detailed style instructions, multi-step descriptions, and layout guidance for reliable image generation.
Accurate prompt following
The GPT-Image-1 API produces clear, readable text directly within images, making it well-suited for infographics, product labels, UI mockups, and other text-based visual content.
Consistent text rendering
The GPT-Image-1 API enables flexible image editing, including mask-based inpainting and reference-guided adjustments, allowing developers to modify selected areas without recreating the full image.
Image editing and inpainting
GPT-Image-1 can handle complex prompts involving up to 10–20 distinct objects, supporting structured compositions such as product grids, group scenes, and illustrated guides.
Multi-object scene generation
The GPT-Image-1 API allows developers to configure image quality levels, resolution, output format (PNG, JPEG, WebP), background transparency, and moderation sensitivity for content safety.
Customizable output and content moderation

Pricing and Quality Levels for GPT-Image-1 API
GPT-Image-1 API uses token-based pricing — $5 per million text tokens, $10 per million image inputs, and $40 per million image outputs. In practice, this means about $0.02 (low), $0.07 (medium), and $0.19 (high) per square image, depending on quality.
Prompt Examples for GPT-Image-1
Example: Generate Images with GPT-Image-1
Prompt: A children’s book drawing of a veterinarian using a stethoscope to listen to the heartbeat of a baby otter.
Example: Edit Images with GPT-Image-1
Prompt: A photorealistic image of a gift basket on a white background labeled 'Relax & Unwind,' containing all the items from the reference pictures.
Example: Edit an image using a mask (inpainting)
Prompt: A sunlit indoor lounge area with a pool containing a flamingo.
Example: Ghibli-Style Image Conversion
Prompt: Convert This Image to Ghibli-Style.
Example: AI Action Figure Generation
Prompt: Design a vintage action figure with a man in a brown leather jacket holding a map. Use an aged cardboard background with bold retro fonts for 'JOHN' and 'RELIC HUNTER'. Place the figure in a plastic blister with a cartoon-style illustration next to it, evoking 80s action figure nostalgia.
