Nanobanana Pro/2

What it is

Nano Banana started life as Google’s internal code name for Gemini’s image generation and editing — then the model showed up on public leaderboards under that name, and it stuck, because apparently humans still like funny names. Officially it’s Gemini; practically, nobody calls it that. The lineup that matters now is two models. Nano Banana Pro (Gemini 3 Pro Image, late 2025) is the control-and-quality pick. Nano Banana 2 (Gemini 3.1 Flash Image, February 2026) folded most of Pro’s quality into Flash speed and is now the default image model across the Gemini ecosystem — the app, Search, Lens. For all of 2’s advances, though, Pro still tends to produce the most cinematic results. The original Nano Banana is legacy at this point; these two are the conversation.

The two models that matter

Pro is the deliberate one: up to 4K output, the strongest prompt adherence in the family, and the version where the paid tiers actually buy you working room. Nano Banana 2 is the volume one — near-Pro output at a speed that changes how you iterate, with web-search-grounded generation, support for up to 14 reference images, and character consistency across multiple subjects in a single workflow.

My working split: Pro at 2K for cinematic outputs — that’s where the most filmic results live. Nano Banana 2 for the quick hits — cartoony, illustrative work, and anything informational, where its real-world knowledge is a genuine strength of its own. So: informational and illustrative, Nano Banana 2; cinematic, Pro at 2K.

One note worth underlining: the last place you actually want to use Nano Banana is the Gemini chat interface itself. Always run it through the API or Google’s Flow.

The prompt-technique thread

I’ve covered this thread more than any other image tool on the channel — prompt techniques, workflow hacks, comparison tests. The most current entry is The SECRET to Stunning AI Video Prompts, which showcases a set of prompt techniques that are extremely useful for Nano Banana Pro. That video was built on Flora. If you’re brand new to the tool, the Ultimate Deep Dive is still the place to start.

Where it sits

Despite its age — in AI terms, at least — Nano Banana Pro remains the go-to image editor for cinematic work, and Nano Banana 2 is a capable image generator and editor in its own right. The real pressure is GPT-Image 2, which is hot on Pro’s heels despite an occasional tendency toward fuzzy, noisy outputs. And the clock never stops: a Nano Banana 2 Pro release is likely imminent.
