the image linked to by the post is the Pangram LLM-detection report of paragraphs in the first screenshot below, reading "100% AI". in lieu of alt text for the screenshots below, I suggest scrolling through @eicker@lemmy.world's profile and https://lemmy.world/comment/26323310, which the screenshots are of. Look at the vote counts.
I'm not misrepresenting anything. If you take any model and just change the temperature a little bit (it's a setting that controls the influence of the RNG) you can have wildly different output.
Different AI providers using the exact same model will have outputs so different using the same exact prompts you'd think they were in different universes.
They absolutely do not "have the same hallmarks."
This stuff is benchmarked to absurd degrees every time a new model comes out. Just look it up already! You're so obviously arguing from an ignorant position it's silly.
