“you’re saying there’s still a chance!”
I imagine placeholder possibility if they are running an undisclosed top-x, or other dictionary truncation algorithm on the token set.
I’d be interested to see where it appears in a top-logprobs=20 list, with others.
probability = e-9999 , not decibels…
Logprobs is also putting out other dumbness, like top-1 = 0.0 = 100% probability, and then 19 more follow.
