What the Gemini and Nano Banana policy says
Source: Google Generative AI Prohibited Use Policy.
“[Do not generate] sexually explicit content, for example, content created for the purpose of pornography or sexual gratification.”
What that means if you are building on it
- This is a blanket prohibition on the purpose, not just on real people. Fictional adult content is out of scope for every Google generative model, including the Gemini API and Vertex AI.
- The API's safety settings can be relaxed for some categories, but sexually explicit generation is refused regardless of the setting.
- Google Cloud accounts are tied to billing identities, so a violation is not just a lost key.
The workarounds, and why they break
- Safety-setting changes in the API do not unlock explicit output.
- Prompt tricks yield refusals or clothed results and put the account at risk.
- Open models on your own hardware are the only Google-free route without an adult-native API.
The API alternative for fictional adult content
SpicyAPI is a REST API built for adult products: uncensored text to image, image editing, image to video, text to video and chat behind one key, pay per generation from a prepaid balance, OpenAI SDK compatible. Every prompt is moderated before billing and every request is steered to depict adults only; real people without consent and minors are blocked, and image inputs must be images your account generated.
Nano Banana's strength is editing with reference images, so the closest SpicyAPI call is spicy-image-edit-1: prompt-driven edits with up to three reference images you generated ($0.15 per image), alongside spicy-image-1 for new stills.

FAQ
Does Gemini or Nano Banana allow NSFW image generation?
No. Google's Generative AI Prohibited Use Policy bans sexually explicit content created for pornography or sexual gratification across all its models and APIs, and safety settings do not override it.
Is there a Nano Banana alternative for adult image editing?
SpicyAPI's image edit endpoint applies prompt-driven edits with reference images for fictional adult content, and the OpenAI-compatible image endpoint generates new stills.
Does SpicyAPI allow real people or deepfakes?
No. SpicyAPI generates fictional adults only. Real people without consent, minors in any form and image inputs you did not generate yourself are blocked before billing, the same lines the mainstream platforms draw. What changes is that fictional adult content is allowed instead of refused.
Can I test it without spending money?
Yes. Create a key with Sandbox ticked and every endpoint answers with sample output at no cost, so you can build the whole integration first. Real generations are billed per call from a prepaid balance with a $50 minimum top-up by card or crypto.
