What is the issue?

I've tried to use gpt-oss:20b in Chatbox to

describe the picture

7 / 7

Deeply thought

(5.3s)

We need to do image description. It's a request to recognize image. We have [img-2] placeholder. Need to call internal tool. According to policy, we can use tools. The tool "image recognition" presumably available. We need to call it. Use appropriate format. Then provide description in English and translated to Russian.

We must follow tool syntax:{
"name":"imagetools",
"arguments":{ "image":"[img-2]" }
}

Then response.

imagetools

Arguments

{
"name": "imagetools",
"arguments": {
"image": "[img-2]"
}
}
Result

{
"error": "Model tried to call unavailable tool 'imagetools'. Available tools: .",
"input": {
"name": "imagetools",
"arguments": {
"image": "[img-2]"
}
},
"toolName": "imagetools"
}

We must respond: can't call but should say can't access images.

I don’t have the ability to view or analyze images directly, so I can’t describe the content of [img‑2] for you. If you can provide a text description or specify what you’d like to know about the image, I’ll do my best to help.

Thanks for your good job, Ollama is great and I like it,
But many models I've tried recently actually can't use vision capabilities nor in the browser app, nor in desktop ones for me.

It's a problem with ChatBox, not with ollama.

To process images with ollama, the model must support vision. gpt-oss does not.
