OpenAI: chatgpt-image-latest API

chatgpt-image-latest is a dynamic alias in the OpenAI API that always points to the current flagship image generation snapshot used within ChatGPT. As of early 2026, it points to GPT Image 1.5. Moving beyond the diffusion-based architecture of DALL-E 3, this model is a native multimodal powerhouse. Its defining features include near-perfect text rendering, precise local editing (allowing users to modify specific parts of an image without re-rendering the whole), and 4x faster generation speeds. It also supports "Likeness Retention," enabling users to maintain consistent character appearances across different generated scenes using a single reference photo.
