Nano Banana 2 image generation reference

Nano Banana (NB) is Google's Gemini image generation family. NB2 = Gemini 3.1 Flash.

Model selection

Model Best for Tradeoffs
NB1 Existing workflows that already work, lowest cost, speed-critical No thinking, no visual grounding, no extreme ratios
NB2 Default for new projects (~95% of Pro quality) ~15% slower than Pro at 2K, weaker arm/leg composition, spelling errors in infographics
Pro Complex multi-layered prompts, extreme logical constraints, interior scale/logic Most expensive

Decision: Start with NB2. Step up to Pro only if NB2 consistently fails your specific prompt.

Visual grounding (NB2 only)
