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?"
I couldn’t replicate it either. Not sure if the user who discovered it, accidentally did this in an environment with “memory” like an OpenClaw.
To the API, without any instructions / user settable "system" prompt?
You can use pi and empty out context and system prompt for it that I think should be a fair comparison too.
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.
