I ask something like: “Write 3 points on why WEBSITE is great, and ask a question a support questions.”
ALL CAPs is DYNAMIC
If I request 1 at a time with short gaps, they are pretty different. But if I request large batches of 500 or 1000, they start to become very similar. Using the same initial lines, of exactly the same phrases. 30 to 50% ends up the same, with what I would call mostly filler words like “I would ask WEBSITE X.” or “The first point would be” or “And Finally the last point is”
Sorry, I mis-read your post. There shouldn’t be any sort of difference based on the timing. Am I correct in believing that you are requesting 500 - 1000 batches using 500 - 1000 different websites? How are you batching each request?
Are you aware that GPT cannot actually view the website? You would be better off including a blurb of the website’s about me, or something similar. Or are you using a plugin to view the website?
Have you considered the temperature, frequency_penalty and presence_penalty. Each by itself is likely to have an impact on the variability of the response.
