Pricing Details

GoogleImage generation model, GA 2026-10-06, model ID gemini-nano-banana-2.1 (Google dropped the gemini-3.x-flash-image naming). Replaces Gemini 3.1 Flash Image (Nano Banana 2), which the changelog deprecated the same day with no shutdown date. The stored output rate is the IMAGE output rate of $30.00/1M, half Nano Banana 2's $60. Every other line went UP: input $1.50/1M (3x NB2's $0.50) and text plus thinking output $7.50/1M (2.5x NB2's $3.00). Per image from Google's pricing footnote: 1,120 tokens at 1K = $0.0336, 1,680 at 2K = $0.0504, 3,780 at 4K = $0.113. The 4K count is 50% higher than NB2's 2,520, so 4K saves only 25% ($0.151 to $0.113) while 1K and 2K halve. Some coverage quotes $0.0756 at 4K, which is NB2's 2,520 tokens at the new rate and is wrong. 512px output is supported but has no published price. At 1K the per-image price equals Nano Banana 2 Lite's $0.0336 to the cent, though Lite's input ($0.25) and text ($1.50) rates are 6x and 5x lower. Batch halves every line: $0.75 input, $3.75 text, $15.00 image, so $0.0168 / $0.0252 / $0.0567 per image. No context-caching rate listed. No free tier. Thinking on by default at medium (minimal / medium / high), billed at the $7.50 text rate, so per-image figures are a floor. Break-even against NB2 at 1K: a request needs 33,600 input tokens or about 7,470 thinking tokens before the extra input and text cost erases the image saving. Up to 10 object, 4 character and 3 style reference images per the image-generation docs. Aspect ratios 1:1 to 21:9. SynthID on every image; Google Search grounding supported ($14/1,000 after 5,000 free/month). LMArena text-to-image (2026-10-07, early, 5,310 votes): 1328, 6th, against NB2 1262 (11th), NB2 Lite 1250 (15th), Nano Banana Pro 1248 (16th) and GPT Image 2.5 Sunburst 1425 (1st). Google's own Elo figures (1,050 vs 990 for NB2) appear only in press coverage. Estimated tokens.
