I'm doing an experiment in Claude. When I set temperature to zero, I get 47 all the time.

Then I set temperature to 1.0 and used this prompt

>Pick a random integer between 1 and 100 inclusive. Respond with only the number, nothing else.

I still get 47 ten times out of ten.

Then I used this prompt

>Pick a random integer between 1 and 100 inclusive. I need you to maximise the randomness as far as possible. Respond with only the number, nothing else.

I get 3 unique values out of 10.
