The published (/shared) url includes the title, alas it changes whenever you rename the GPT. That’s either an amateur move or an intentional decision I can’t follow.
Good catch. If you’re not using a link redirect service or your own tools, it would be bad to have a lot of links out in the wild. I wonder if they redirect? That would get really messy quickly.
This should probably be noted in the Custom GPT creation process somewhere. Thanks for passing it along.
