A tutorial from OSChina walks through nine practical uses of Google's Nano Banana 2.1, released October 6, 2026, covering everything from multi-reference image consistency to iterative "image nurturing," with complete prompts included. The article says the model's base was switched to Gemini 3.6 Flash, bringing capabilities that previously required Pro-tier models — multi-reference consistency, complex local edits and text-heavy posters — down to Flash-level cost and speed.
For people using image models day to day, a concrete workflow list helps gauge which tasks that once needed pricier models can now be handled by a cheaper Flash-tier one.
