KV cache
Saved calculations that help a language AI continue its reply without repeating all its earlier work.
Example
An AI system reuses calculations for earlier tokens while producing later ones.
Why people use it
It avoids repeating some calculations while a language AI continues its answer.
What you'll hear
“Reuse the earlier calculations as the reply grows.”
What this means for you
Distinguish computing work caching from retention and memory features.
Can you control it?
Developer-only
The people building or running the AI choose this setup. An everyday user generally needs their help to change how this part works.
Common questions
- Can the saved calculations use too much memory?
- Yes. A growing cache can use substantial computer memory and limit how much material the service can handle.
- Is this the same as remembering me across chats?
- No. It is a way to reuse calculations during processing, not a personal memory feature.
- Can long conversations use more memory?
- Yes. Keeping more earlier calculations available can increase the memory needed.
