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.

Glorp 5.3 Fast Thinking actually steals this diagram correctly for me locally so I think everyone here is wrong

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!

You're holding the LLM wrong.

It's microsoft's AI though, not even the totally crazed evangelists like that one.
