Token sampling: Nucleus filtering excludes the token that crosses p · case 03
Nucleus filtering excludes the token that crosses p.
Case contract
Sort by descending probability then token ID; retain the shortest prefix whose cumulative mass is at least p. For p<=0 keep none; p>1 keeps all.
Why this case matters
A finite, deterministic token-selection contract isolates one decoding operation from model inference and runtime behavior.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| crossing included | ["a"] | ["a", "b"] | Failed |
