What 100 images cost
| 100 × 1K | 100 × 4K | 100 × 1K batch | |

| Nano Banana Pro | $13.40 | $24.00 | $6.70 |
| Nano Banana 2.1 | $3.36 | $11.30 | $1.68 |
When Pro is worth paying for
Pro earns its price on images with a lot of small text (menus, infographics, packaging), on edits that must keep a face or product identical, and when mixing many references: it accepts up to 14 (6 object, 5 character, 3 style). For drafts, social posts and simple product shots, 2.1 at a quarter of the price is usually indistinguishable.

Questions
How much does Nano Banana Pro cost per image?
$0.134 for a 1K or 2K image and $0.24 for a 4K image through the Gemini API at standard rates. Batch requests cost half.
Is Nano Banana Pro free?
Not through the API: Google lists no free tier for image models. In the Gemini app, access and daily limits depend on your Google plan and change often, so check the app.
Is Nano Banana 2.1 cheaper than Pro?
Yes, about four times cheaper at 1K ($0.034 vs $0.134). Pro is for the highest-fidelity text and detail; 2.1 is the efficient default.
How does it compare with GPT Image 2.6?
OpenAI prices GPT Image 2.6 per token rather than per image, so the cost depends on size and quality setting. GPT Image 2.6 can also output animated GIFs and SVG, which Nano Banana cannot.
