I’ve noticed this too, it’s hilarious(ly bad).
Especially with image generation, which we were using to make some quick avatars for a D&D game. “Draw a picture of an elf.” Generates images of elves that all have one weird earring. “Draw a picture of an elf without an earing.” Great now the elves have even more earrings.
If you mean I have to install Claude’s software on my own computer, no thanks.
