# Nano Banana

> As of 2026-04-14, nano-banana is no longer recommended through /v1/images/generations; this page keeps only the native Gemini controlled-test path

# Nano Banana

```
Controlled testing only
POST /v1beta/models/nano-banana:generateContent
```

As of `2026-04-14`, the latest Crazyrouter production retest for `nano-banana` showed:

* `nano-banana` currently maps to `nano-banana`
* `POST /v1/images/generations` is no longer recommended for `nano-banana`
* `nano-banana:generateContent` can currently return image output
* but billing consistency on that native path is still under review, so it should be documented only as a controlled-test path, not as a stable production integration

<Warning>
  Do not keep documenting `nano-banana` as a recommended `/v1/images/generations` model. Even though the native Gemini path can return image output, it should not be presented as a stable production capability until billing consistency is revalidated.
</Warning>

## Current Risks

### 1. `/v1/images/generations` is no longer recommended

On `2026-04-14`, both production and local `4000` retests of `nano-banana` through the public Images-compatible route hit the same failure class:

* `Unknown name "imageOutputOptions" at 'generation_config.image_config'`
* an abnormal billing sample on a failed request

That makes the public Images-compatible route unsuitable as the documented customer entry point for `nano-banana`.

### 2. The native path still has billing-consistency risk

In the current production retest:

* `POST /v1beta/models/nano-banana:generateContent` returned an image successfully
* but the consumption log `quota` and the token-side `used_quota` delta did not line up

So this path should currently be documented as "controlled testing only", not as "stable production integration".

## Current Recommendation

1. If you need a usable image-generation or image-editing route right now, start with [Nano Banana 2](/ru/images/nano-banana-2)
2. If you must evaluate `nano-banana`, use only the native Gemini `generateContent` route
3. Do not put `nano-banana` into formal production traffic until billing consistency is cleared
4. Do not use `POST /v1/images/generations` with `model: "nano-banana"`

## Controlled-Test Template

The request below is for same-day controlled testing only. It does not imply stable production readiness:

```bash theme={null}
curl "https://api.crazyrouter.com/v1beta/models/nano-banana:generateContent?key=YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "contents": [
      {
        "role": "user",
        "parts": [
          {
            "text": "Generate an IMAGE of a clean banana icon on a white background. Return image output."
          }
        ]
      }
    ],
    "generationConfig": {
      "responseModalities": ["TEXT", "IMAGE"]
    }
  }'
```

## Legacy Route

The following legacy pattern is no longer recommended:

```bash theme={null}
curl -X POST https://api.crazyrouter.com/v1/images/generations \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "model": "nano-banana",
    "prompt": "..."
  }'
```

This is not just a documentation cleanup. The route is currently unhealthy in both production and local retests.

<Note>
  If you need the currently healthier Gemini image path on Crazyrouter, see [Gemini Image Generation](/ru/chat/gemini/image-gen). If you need the more usable Nano Banana-family route right now, start with [Nano Banana 2](/ru/images/nano-banana-2).
