" Your role is the average of what you spend your time on. "

" It's cognitively easier to evaluate the work somebody else did than to do it yourself. That's why LLMs can evaluate LLMs. "

" Don’t overcomplicate workflows; the simplest thing that could possibly work is often best. "

" Use custom systems for experts to quickly review and rate outputs, making feedback cycles much faster. "

" There is a large and growing capability overhang in these models we haven’t discovered yet. "

" The Rosen Bot can turn a simple prompt into a five-week training program for your team. "

" Tool use lets the model decide itself when to call external APIs or services to get needed information. "

" If you launch in the US and politeness is an issue, first try to fix it with prompts; only if that fails should you build an eval. "

" Evals are the key to knowing when an AI’s output is good enough. "

" People tend to trust AI a lot because it seems very confident—even when it’s not always accurate. "

" Chatbots aren’t just the language model—they have structure around intent classification, safety checks, and session memory simulation. "

" We invented the ‘prompt deep dive’ technique to spend lots of time on one prompt to deeply understand it. "
