Gemini Pro Image — 4K Output, 8 References, 64K Context

It generates up to 4K resolution output, accepts up to 8 reference images that are blended into a single coherent result, and operates with a 64K input context window. Multi-turn dialogue editing lets you refine outputs without full regeneration, and search-grounded generation draws on Google's knowledge base for accurate diagrams, infographics, and scientific visuals.
