What people use it for
Sustain an end-to-end refactor
Feed a full repository and a design doc, ask for a planned refactor, receive step-by-step edits, unit test updates and a final diff you can apply. Kimi K3’s long context keeps file history and tests in scope so the outcome is an executable patch and test results.
Debug code with images and logs
Upload screenshots, error traces and the failing file, then ask Kimi K3 to pinpoint the fault, propose fixes and generate a minimal reproduction test. The model’s native vision plus long context helps it correlate console output, stack traces and recent commits to a concrete fix.
Create technical documentation from code and video
Give Kimi K3 a recorded walkthrough, repository files and API examples, and get release notes, API reference pages and example snippets. The output is ready-to-publish documentation tied to specific files and code lines.
Why it is worth it

Questions people ask
When should I choose Kimi K3 instead of a smaller model?
Choose Kimi K3 for long-horizon engineering tasks, repo-scale work, multimodal debugging or when you need a single model to keep large history and visual context in scope. For short text edits or lightweight chat a smaller model will be cheaper and faster.
Can Kimi K3 accept screenshots and video along with code?
Yes. Kimi K3 supports native image and video inputs alongside text, letting you attach screenshots, recordings and logs so the model can reason across modalities.
How does billing work for Kimi K3 on Katteb?
Kimi K3 on Katteb is billed per message by usage in credits. The model costs 28 credits per message; you can switch models mid-chat and compare results without creating separate sessions.
