llama.cpp seems to choose greedy decoding when temperature < 0. Is this behavior available in ollama?

Shouldn't top_k = 1 be greedy decoding?

@shenghu I am also curious about this, in my experience setting temperature to 0 does not make it completely deterministic, nor does setting top_k=1 though, which should in any case be equivalent theoretically.
