Quick definition
Top-k sampling limits generation to the k most probable tokens.
- Category: Generation
- Focus: output style and randomness
- Used in: Lower randomness for precise, repeatable answers.
What it means
It constrains randomness by excluding low probability tokens. In generation workflows, top-k often shapes output style and randomness.
How it works
Generation settings control how the model samples tokens. They trade off creativity, determinism, and safety.
Why it matters
Generation settings trade off creativity, determinism, and safety.
Common use cases
- Lower randomness for precise, repeatable answers.
- Higher randomness for brainstorming and creative tasks.
- Stopping rules to end output at the right time.
Example
Top-k of 40 picks from the 40 most likely tokens.
Pitfalls and tips
High randomness can reduce accuracy while low randomness can be repetitive. Tune per task and evaluate results.
