Nano Banana Pricing 2026: Gemini API Cost per Image ($0.0336–$0.24) & Google AI Plans ($0–$199.99/mo)

Quick answer: on the Gemini API pricing page, Nano Banana 2.1 is $0.0336 per 1K image, Nano Banana 2 is $0.067 per 1K image, Nano Banana 2 Lite is $0.0336 per 1K image and Nano Banana Pro is $0.134 per 1K or 2K image ($0.24 at 4K), with no free API tier for these models. In the Gemini app, per Google’s plans page, Free is $0/month, AI Plus $4.99/month, AI Pro $19.99/month and AI Ultra $99.99 or $199.99/month, each billed monthly. If you need a render of your own building rather than an image from a prompt, Render a House is the more efficient alternative for architecture, a no-GPU, browser-based option that starts free with 3 credits a day; failed renders don't use credits, and each render includes up to 2 free retries if the result isn't right.

Updated October 2026. Every Google figure on this page comes from Google’s own pages, checked on 27 October 2026 and linked inline. Consumer prices are the US prices in USD; Google shows plans by country. Render a House figures come from our live plan configuration.

Developers pay per output image. Google prices image output in tokens and converts it to a per-image figure on the Gemini API pricing page; the table below uses those per-image figures for the paid tier.

Resolution support follows Google’s image generation docs: 1K, 2K and 4K output, 0.5K only on Nano Banana 2, and 1K only on Nano Banana 2 Lite. The original Nano Banana (Gemini 2.5 Flash Image) is still priced on the page, but Google marks it deprecated with a shutdown date of October 2, 2026, so plan new work on the newer models. The free tier shows “Not available” for every image model.

Batch, grounding and input costs

• Batch API: half price on every image model above, per the pricing page, in exchange for asynchronous processing. Nano Banana Pro also lists Flex at the Batch rate and Priority at $216 per 1M image tokens.
• Input: text and reference images are billed as input tokens, for example $1.50 per 1M tokens on Nano Banana 2.1 and $2.00 per 1M on Nano Banana Pro, which Google equates to about $0.0011 per input image. The docs allow up to 14 reference images per request.
• Grounding with Google Search: 5,000 free search requests per month shared across Gemini 3 and newer models, then $14 per 1,000 requests.

Most people use Nano Banana inside the Gemini app. Google sells access through Google AI plans, listed on gemini.google/subscriptions and Google One.

Free plan and limits

The free plan includes image generation and editing. Google’s image generation page says Nano Banana is available for free and that a Google AI plan unlocks Nano Banana 2.1. Per the Gemini Apps limits page, limits are compute-based, refresh every 5 hours until you reach a weekly limit, and image generation uses more of the allowance than text. A fixed number of images per day: Not published (checked October 2026). Free trial of a paid plan: Not published on the plans page (checked October 2026).

Google AI Plus — $4.99/mo

The Google One page shows an annual option only for AI Pro: $199.99 a year, or $16.67 a month. Twelve monthly payments of $19.99 come to $239.88, so paying yearly saves $39.89. Annual prices for AI Plus and AI Ultra: Not published (checked October 2026).

API education pricing: Not published (checked October 2026).

• Higher resolution on the API: a 4K image costs about 1.8x the 1K price on Nano Banana Pro, 2.3x on Nano Banana 2 and 3.4x on Nano Banana 2.1.
• Retries: each regenerated API image is billed again; the pricing page lists no free retries.
• Search grounding beyond the 5,000 free monthly requests, at $14 per 1,000.
• Watermark: Google’s image docs say all generated images include a SynthID watermark; no plan removes it.

Nano Banana is good value for quick concept images, style tests and photo edits: the free Gemini plan covers light use, and the API is cheap enough per image to build into your own tools. Our Nano Banana for architecture guide covers where it helps in practice and our prompt guide has templates.

Render a House is an AI rendering tool for architects and real estate. It runs in the browser with no GPU and no API code, and it starts from your own design: upload a SketchUp .skp directly, a GLB, GLTF, OBJ or STL model, a sketch, a photo, or a plan exported to PNG/JPG. Large images are downscaled automatically, and renders take about 30–60 seconds.

Free is 3 credits a day at 1K with a watermark, no card required. Pro is $39/month billed monthly or $312/year ($26/month billed annually) for 240 credits a month. A 1K render costs 1 credit, 2K costs 1.5 and 4K costs 2; 4K is only on Pro, and video is on paid plans only. A bad render gets up to 2 free retries, projects can be shared by email with edit access (there are no team seats or roles), and support is in the app chat and on the support page.
