Vision Model Required for Images

If your current model does not support vision, Jan will automatically prompt you to download Jan V2 VL — the recommended vision model (~5GB). Click Download to install it, then you'll be ready to chat with images.

All files are processed locally on your machine. When using a local model such as Jan's built-in models, your files never leave your device — inference happens entirely on your own hardware with full privacy. If you use a cloud model provider (e.g. OpenAI, Anthropic), files are sent to that provider's API as part of the request.
