Nano Banana 2.1
The current Nano Banana generation from Google DeepMind. It keeps everything Nano Banana 2 is known for, strong prompt adherence, native multi-image references and clean photographic rendering, and runs here at 1K for a fraction of the Nano Banana 2 credit cost. The sensible default when you want Google's image quality without paying the flagship rate; step up to Nano Banana Pro only when you need 4K out of the model itself.

Nano Banana 2
Google DeepMind's Gemini 3-powered flagship for text-to-image. Renders up to 4K with industry-leading prompt adherence, native multi-image references, and web search grounding for factual scenes. Ideal for product photography with brand consistency, character series across multi-shot campaigns, and complex compositional work that benefits from compositing several references at once.
Nano Banana Pro
The premium tier of Google's Nano Banana lineup. Tuned for magazine-cover fidelity at 4K, with the strongest identity preservation in the family across faces, products, and brand elements. Best when the cost per image is justified by the output going into print, paid ads, or hero placements where every detail matters.
GPT Image 2 Medium
OpenAI's GPT Image 2 at the medium quality tier. Combines elite prompt adherence with the strongest typography rendering of any image model: exact text in quotes, complex layouts, and packaging mockups all just work. The default choice for production marketing creative when GPT Image 2 High's premium pricing isn't justified.
Seedream 5 Pro
The flagship of the Seedream line. Generates sharp, high-detail images from a text prompt, and can take a reference image to lock a character, product, or style. Carries the cinematic Seedream palette and mood at higher fidelity than Seedream 5 Lite — reach for Lite when you're iterating high-volume and Pro for the hero shot.
