Nano Banana 2.1 is Google’s image model for creating a photo from text or editing owned photos. MixVio keeps it as its own page, separate from Nano Banana 2. Each run returns one PNG. ### Which resolutions and ratios can I use? Choose 1K, 2K, or 4K. 0.5K is not available. Ratio defaults to Auto and includes 21:9, 16:9, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 9:16, 4:1, 1:4, 8:1, and 1:8. 9:21 is not offered. ### How many reference photos can I attach? Image edit accepts 1 to 14 JPEG, PNG, or WebP photos. Text to image does not take references. “Up to four characters and ten objects” is prompting guidance, not two separate upload limits. Video, audio, and PDF inputs are not exposed. ### What do Thinking and Web search change? Thinking is Minimal, Medium, or High. Medium is the default and is sent on every request. Thinking is not a quality menu. Web search is off until you turn it on. Medium and Minimal stay on the resolution price. High thinking alone stays inside the same credit ceil as the resolution. Web search moves the quote to 7 credits at 1K, 10 at 2K, and 13 at 4K. 4K with web search and high thinking is 13 credits. ### How many credits does Nano Banana 2.1 use? A default 1K image is 6 credits, 2K is 9, and 4K is 12. With web search those become 7, 10, and 13. The maximum on MixVio is 13 credits for 4K with web search and high thinking. Generate and edit share that rate. Confirm the estimate before you generate. Failed runs cost no credits. ### Is Nano Banana 2.1 free, and is there a watermark? The route is not a free unlimited generator. Free-plan images can run when your balance covers the quote; those outputs carry a visible MixVio watermark and stay at the plan’s resolution cap. Paid plans remove that MixVio watermark. Google still applies SynthID to Nano Banana 2.1 outputs. MixVio does not claim a SynthID-free download. ### How does Nano Banana 2.1 compare with Nano Banana 2, Nano Banana Pro, and GPT Image 2.5? Use Nano Banana 2.1 when you want 1K–4K photos, up to 14 references, optional web search, and Thinking set to Minimal, Medium, or High. Nano Banana 2 stays the lower-credit generate-and-edit route. Nano Banana Pro is the detailed product and type pass in that older family. GPT Image 2.5 is the keep-and-change route with Flare or Sunburst. The comparison table uses the live MixVio routes. ### What should I review before I publish? Small text can blur at 1K. Character consistency across references is imperfect, so check faces, hands, and labels. SynthID is present on outputs. MixVio does not expose batch counts, a mask brush, multi-turn chat, or a 1 million-token context control.
