Best forLong, complex work
THE SIMPLE VERSION
What is Kimi K3?
Kimi is Moonshot AI's chat and agent workspace. K3 is its most capable model, with native visual understanding and support for very long context. It can search the web, analyse documents and images, create editable files, build websites and help with coding. Beginners can still start with a normal question, but K3 and agent tools use credits while faster K2.6 chat is free.
✓ A good fit if you want to…
- Work with long documents or mixed files
- Need research plus an editable deliverable
- Want chat, agents and coding in one workspace
– Choose another tool if you…
- Only need quick, simple everyday chat
- Do not want to monitor a shared credit pool
- Need personal chats excluded from training by default
