Nano Banana 2 is Google's Gemini 3.1 Flash Image model. It creates images from a text prompt and edits existing ones from plain-language instructions — say 'add a sunset glow', 'replace the chair with a throne' or 'remove the background' and it applies the change. Attach reference images and it switches to editing automatically. Nano Banana 2 Lite is a lighter, cheaper variant.
Intuitive Natural Language Editing
Describe the change in plain language and Nano Banana 2 applies it — object swaps, background changes, facial refinements, style shifts.
Text-to-Image Too
Not only edits: describe a scene from scratch and Nano Banana 2 draws it; attach references and it edits instead.
Precision Object & Background Editing
Pixel-level object replacement, background modification, and facial refinement without distortions across iterations.
Physics-Aware Outputs
Edits maintain coherent lighting, natural shadows, and correct spatial relationships — outputs look real, not pasted.
Seedream 4.5 by ByteDance generates 2K resolution images in under 1.8 seconds and scales to 4K. It accepts up to 14 reference images as input and can output up to 6 images per generation for batch workflows. Built for precise instruction-based editing, strong feature preservation, and knowledge-based generation — it understands abstract concepts and converts them into accurate visuals.
Ultra-Fast 2K Generation
Generates 2K resolution images in under 1.8 seconds — up to 4K for print-quality output.
Multi-Image Input & Output
Accepts up to 14 reference images as input. Generates up to 6 images per request for batch workflows — all consistent with each other.
Precise Instruction Editing
Natural language editing that preserves identity — change style, lighting, background without the over-processed AI look.
Knowledge-Based Generation
Understands abstract concepts, complex reasoning, and converts deep intent into visually accurate results — not just literal prompt matching.
It depends on the job. Nano Banana 2: Gemini 3.1 Flash Image — Fast Generation and Plain-Language Edits. Seedream 4.5: ByteDance's 4K Image Model — 2K in Under 1.8 Seconds. Both are on The Factory on one credit balance, so you can run the same prompt on each and keep the better result.
