Daily bunny no.3164 finds the smugglers' hideout

I’m all for using LLMs when it makes sense, but the walls of text are unnecessary where a few bullet points suffice.

Captain Haddock looking very frazzled, saying, “What a week, huh?” Tintin leans into the frame and says, “Captain, it’s Wednesday.” Snowy is very excited about the drink he has found.

Writing LLM evaluation criteria is an art

Convenient!
