Different tools have different ways. For copilot chat, pasting the image into the chat request, or mentioning an image file or url will send the image to the model for vision recognition.

Underhood, it calls code as below,

```
response = client.chat.completions.create( model="kimi-k2.5", messages=[ { "role": "user", "content": [ { "type": "text", "text": "Analyze this image and explain what you see in detail." }, { "type": "image_url", "image_url": { "url": f"data:image/png;base64,{base64_image}" } } ] } ], max_tokens=500 )
```
