I sent Claude Opus 5 '–-' and it wrote me 5k tokens about a cartographer (austinsnerdythings.com)

This post is obviously AI-written and it’s practically incomprehensible without some background context that’s missing here.

Just tried this in Opus 5:

"Looks like your message came through empty, just a dash. What did you want to ask?"

People should just try base models, or models where you have access to prefills. I guess so many who use LLMs nowadays have never actually experimented with a text completion endpoint locally/over API.
