OpenAI: GPT Image 1.5

Image Generation
openai/gpt-image-1.5
CompareGet Started

GPT Image 1.5 is OpenAI's image generation model, released on 2025-12-16, built for better instruction following and closer adherence to prompts. It accepts image input alongside text, so it covers both text-to-image generation and image-guided editing workflows, and it supports prompt caching to cut the cost of repeated prompt prefixes. Cached image input is billed at a lower rate than fresh image input, which helps on iterative generation where the same reference material is reused across requests. Accessible via the OpenAI-compatible protocol through Ofox.
