GPT Image 1.5
GPT Image 1.5 is an image generation model from OpenAI that supports source image inputs and configurable output settings.
OpenAIText-to-image generation with source image support
GPT Image 1.5 is an image generation model developed by OpenAI, released in December 2025. It accepts text prompts alongside optional source images, allowing users to generate new images that reference or build upon existing visual inputs. The model supports configurable parameters including output size and background style, giving developers control over the composition of generated results.
GPT Image 1.5 is suited for workflows that require image creation from descriptive prompts, image-to-image generation, and tasks where background transparency or specific dimensions are needed. It operates with a 32,000-token context window for prompt input and is priced at approximately $0.15 per image on a dynamic basis. The model is available as a first-party provider on MindStudio without requiring separate API key configuration.
