LLM Next-Token Probability Lab

Softmax & Nucleus Sampling
Sampling Hyperparameters
Temperature (T) 1.0
Controls randomness: Lower = Deterministic peak; Higher = Flat uniform distribution.
Top-K Truncation 5
Limits sampling to the highest K candidate logits.
Top-P Nucleus Mass 0.99
Dynamically truncates tokens after cumulative probability exceeds Top-P.
Raw Logits Scrubber
Token Logit ($z_i$) Exp $e^{z_i/T}$ Prob $P(t_i)$ Status
Softmax Scaling Equation:
$$P(t_i) = \frac{\exp(z_i / T)}{\sum_j \exp(z_j / T)}$$
Active Mass: 100% | Tokens Retained: 5
