🌐 Web-Grounded Generation
Gemini 3.1 Flash Image can use Google Search grounding when the integration is enabled. Grounding can help with current information, but generated visual details still require review. Google documents no Search grounding for Nano Banana 2 Lite.
🖼️ 14 Reference Images
Plykit's current interface accepts up to 14 reference inputs. Google's official guidance separates up to 10 high-fidelity object references from up to 4 character references, so the composition of the reference set matters. Nano Banana 2 Lite is not optimized for multi-reference workflows.
👤 Character Consistency (Up to 4)
NB2 can maintain consistent character appearance across up to 4 characters in a single generation session. This is critical for e-commerce product models, brand mascots, comic/manga creation, and any workflow that requires recognizable faces across multiple outputs.
📏 14 Aspect Ratios
In addition to standard ratios, Gemini 3.1 Flash Image documents extended wide and tall formats for banners, stories, and panoramic compositions.
