Waiting for the LLM evangelists to tell us that their box of weights of choice did that on purpose to create engagement as a sentient entity understanding the nature of tech marketing, or that OP should try again with quatuor 4.9-extended (that really ships AGI with the $5k monthly subscription addon) because it refactored their pet project last week into a compilable state, after only boiling 3 oceans.
Using an LLM to generate an image of a diagram is not a good idea, but you can get really good results if you ask it to generate a diagram.io SVG (or a Miro diagram through their MCP).
I sometimes ask Claude to read some code and generate a process diagram of it, and it works surprisingly well!
It's microsoft's AI though, not even the totally crazed evangelists like that one.
Glorp 5.3 Fast Thinking actually steals this diagram correctly for me locally so I think everyone here is wrong
