How to Use Kimi VL to Read Screenshots and PDFs
Kimi VL is Moonshot AI’s vision-language model, which takes an image plus a question and answers about what it sees. Screenshots, charts, scanned pages, and diagrams are all fair game. You call it through Moonshot’s API or the Kimi app. First image question takes a few minutes.
What Is Kimi VL Good At?
Documents with layout. A scanned invoice, a screenshot of a dashboard, a chart with numbers – Kimi VL reads structure, not just pixels. The long-context heritage of the Kimi line means it handles multi-page input better than a model built purely for single photos.
It is not an image generator. Give it text and it answers in text. If you need image creation, that is a different class of tool.
How Do You Send an Image?
- Export the page or screenshot at a readable resolution – too small and text blurs.
- Send the image with a specific question, not “describe this”.
- Ask for the exact field or number you need, such as “total due”.
- Request a confidence note or “not found” if the value is unreadable.
- For multi-page files, convert to images and send them in order.
Specific questions return specific answers. “Describe this” returns prose you cannot use in a pipeline.
What Kinds of Input Work Best?
| Input | Result |
|---|---|
| Clean UI screenshots | Strong |
| Printed charts | Strong |
| Scanned documents | Good if sharp |
| Handwriting | Mixed |
| Low-res photos of text | Weak |
| Dense small print | Weak |
Sharpness beats resolution. A clean 1080p screenshot usually beats a blurry 4K photo every time.
Is Kimi VL Free?
The Kimi app has a free tier with usage limits, and API access is billed per request with image inputs costing more than plain text. For occasional document reads, the app is enough. For pipeline work, the API is what you want, and image tokens make each call pricier than a text-only one, so resizing inputs down to what is actually readable saves real money.
Where Does It Stumble?
Precise numeric extraction from busy charts, and handwriting. It can read a number off a table but misreads a value wedged between gridlines. For anything financial, treat its output as a draft and verify against the source. If your task is pure text at scale, a long-context text model like MiniMax M3 is cheaper and does not need images at all.
Quick Summary
- Kimi VL is Moonshot AI’s vision-language model for images plus questions.
- Best for clean screenshots, printed charts, and sharp scans.
- Ask for the exact field you need; “describe this” is useless in a pipeline.
- Image tokens cost more than text – resize before sending.
- Verify numeric extraction; it misreads busy charts and handwriting.
