# Gemini Image Editing

# Gemini Image Editing

```
POST /v1beta/models/{model}:generateContent
```

As of April 14, 2026, the latest Crazyrouter retest for Gemini image-editing-related routes showed:

* native `nano-banana-2:generateContent` can now return image output again
* native `nano-banana:generateContent` can also return image output, but billing consistency is still under review
* the Nano Banana-family public Images-compatible route through `POST /v1/images/generations` is currently unhealthy

The unhealthy path right now is the older public Images-compatible layer, not every Gemini-native image path. For editing and reference-image workloads, the current guidance should converge on native Gemini `generateContent`.

<Warning>
  Do not keep documenting Nano Banana-family `POST /v1/images/generations` as the stable image-editing route. `nano-banana-2` should move to `nano-banana-2:generateContent`, while `nano-banana` remains controlled-testing only.
</Warning>

<Note>
  The more usable path right now is [Nano Banana 2](/en/images/nano-banana-2), which now points to native Gemini `nano-banana-2:generateContent`.
  [Nano Banana](/en/images/nano-banana) now keeps only the controlled-test note for `nano-banana:generateContent`, not a stable production recommendation.
</Note>

***

## Current Recommendation

1. If your goal is Gemini text-to-image, use [Gemini Image Generation](/en/chat/gemini/image-gen)
2. If your goal is a currently usable reference-image editing route, start with [Nano Banana 2](/en/images/nano-banana-2)
3. If you must evaluate `nano-banana`, follow the controlled-test guidance on [Nano Banana](/en/images/nano-banana)
4. Do not keep treating `POST /v1/images/generations` as the default entry point for the Nano Banana family

## Retest Template

This is now the more recommended minimal template for retesting or integration. The same workload should no longer be documented through `/v1/images/generations`:

```bash theme={null}
curl "https://api.crazyrouter.com/v1beta/models/nano-banana-2:generateContent?key=YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "contents": [
      {
        "role": "user",
        "parts": [
          {"text": "Edit this image: change the background to blue and keep the main square visible. Return image output."},
          {
            "inlineData": {
              "mimeType": "image/png",
              "data": "iVBORw0KGgoAAA..."
            }
          }
        ]
      }
    ],
    "generationConfig": {
      "responseModalities": ["IMAGE"]
    }
  }'
```
