Security and enterprise
Model available exclusively through OpenAI's cloud infrastructure (closed weights). Thinking mode and advanced features are restricted to paid plans (Plus, Pro, Business, Enterprise). API access requires OpenAI developer account verification; organizational verification may be required for full access to GPT Image models via API.
Technical information
The model enforces content policy at generation time — requests that violate the policy return a 400 error (BadRequestError) with a content_policy message. AI-generated content is tagged with AI metadata. Transparent background (PNG with alpha channel) is not supported in the Responses API tool option — use gpt-image-1.5 for that purpose. Free tier access is limited to standard/instant mode with a restricted number of generations (approximately 2 images/day per tester reports). Streaming, function calling, and structured outputs are not supported by the gpt-image-2 API (confirmed on the model's page).
