Frequently Asked Questions
Can I generate images for free with the signup bonus?
No. New users receive 4 credits upon signup, but each Nano Banana 2.1 image costs 8 credits. You will need to purchase a subscription to generate any images with this model.
Why does Nano Banana 2.1 cost 8 credits per image?
Nano Banana 2.1 generates 4K ultra-high-resolution images (4096×4096) with state-of-the-art quality. The computational cost for this level of detail and resolution is significantly higher than standard models, reflected in the credit pricing.
Do my credits expire?
Yes. Credits expire at the end of each monthly billing cycle and do not carry over. Unused credits from one month cannot be used in the next month.
What happens to my unused credits when I cancel?
When you cancel your subscription, you can continue using your remaining credits until the end of your current billing period. After that, all unused credits expire and are not refunded.
Which subscription plan should I choose?
It depends on your usage: Basic (¥9.90/month, 800 credits) allows 100 images—good for casual use. Pro (¥19.90/month, 2000 credits) provides 250 images—suitable for regular content creators. Premium (¥59.90/month, 8000 credits) offers 1000 images—ideal for professionals and heavy users.
What resolution do I actually get?
All Nano Banana 2.1 images are generated at the maximum resolution supported by your selected aspect ratio, up to 4096×4096 pixels for square (1:1) format. Other ratios maintain similar total pixel counts with adjusted dimensions.
Can I use generated images commercially?
Yes. You retain full commercial rights to images you generate with Nano Banana 2.1. You may use them in any project, including commercial work, marketing, and resale, without attribution or additional fees.
How do I write better prompts?
Be specific and descriptive: include subject details, style (e.g., "photorealistic", "oil painting"), lighting (e.g., "golden hour", "studio lighting"), mood, colors, and composition. Use negative prompts to exclude unwanted elements. Experiment and iterate based on results.
What if the generated image is not what I expected?
Credits are consumed upon generation, even if the result does not match expectations. Refine your prompt and try again. Clearer, more detailed descriptions typically yield better results. Review successful examples for prompt inspiration.
Is there an API for Nano Banana 2.1?
Yes. Nano Banana 2.1 is available via REST API for developers who want to integrate image generation into their applications. API access is included with all subscription plans. Documentation is available in your account dashboard.
How long does generation take?
Most images generate in 5-15 seconds, depending on complexity and current server load. High-resolution 4K output requires more processing time than standard models.
Can I cancel my subscription anytime?
Yes. You can cancel your subscription at any time from your account settings. Your access continues until the end of the current billing period, after which renewal stops and remaining credits expire.
