How does the temperature setting in a decoding algorithm influence the probability distribution over the vocabulary?

AIncreasing the temperature removes the impact of the most likely word.

BDecreasing the temperature broadens the distribution, making less likely words more probable.

CIncreasing the temperature flattens the distribution, allowing for more varied word choices.

DTemperature has no effect on probability distribution; it only changes the speed of decoding.

Show Suggested Answer

Suggested Answer: C

Comprehensive and Detailed In-Depth Explanation=

Temperature adjusts the softmax distribution in decoding. Increasing it (e.g., to 2.0) flattens the curve, giving lower-probability words a better chance, thus increasing diversity---Option C is correct. Option A exaggerates---top words still have impact, just less dominance. Option B is backwards---decreasing temperature sharpens, not broadens. Option D is false---temperature directly alters distribution, not speed. This controls output creativity.

: OCI 2025 Generative AI documentation likely reiterates temperature effects under decoding parameters.
