Nano Banana 2 – Google's Free 4K AI Image Generator

Built on Gemini 3 Flash. Solves major AI image generation problems: accurate in-image text rendering, character consistency across generations, and fast iteration (~10s per 4K image). Free access. Supports natural language editing and integrates with video generation pipelines. Competes directly with Midjourney/DALL-E 3 but with better visual reasoning and no subscription required.
