GPT Image 2.6 Sunburst - access through LLMTR
OpenAI's image model for work where detail, layout, and precise edits matter; to keep characters, products, or brand elements consistent across edits, use medium quality or above. It generates images, animated GIFs, and SVGs from text, edits images on /v1/images/edits, and lets you mark what should change with a transparent PNG. Billing is per token; it rises with quality and varies with size and aspect ratio.
