What kind of prompts work best?

Gemini 2.5 Flash understands detailed, descriptive prompts. Include information about style, composition, lighting, colors, and mood. For example: 'A serene mountain landscape at sunset with vibrant orange and purple skies, photorealistic style' works better than just 'mountain'.

There are no hard limits on the number of images you can generate. However, you can generate up to 4 images per API request. For high-volume usage, we recommend implementing proper rate limiting and consider our enterprise plans for enhanced support.
