Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
Linked in a thread on how calibrated Jev's outputs are, using a dice example where the expected output is a probability distribution rather than random generation.
Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Thinking about LLMs.

What Hacker News says?
I tested Jev with a fair die 400 times without telling it the die result. The true probability of face 1 is 1/6, but Jev always chose face 1 and the probability it returned was about 83%. I also tested with a fair coin 200 times and got 0.92 probability. I did several tests and I think Jev is good at problems with a correct answer but weak at problems about actual probabilities whose answers can't be known at all. W…

HN discussionIn the dice example[0] and in this one, the expected output is a distribution e.g. "1: 16.7%, 2: 16.7%...", not a random generation. I agree that in implementation , the architecture is not designed to accurately calculate or incorporate any known uncertainties like these, but the task itself is completely reasonable and arguably trivial. IMO the lesson here is: even in trivial cases, Jev's outputs are just ~reasona…
