" Skills are like onboarding material for the model; you write them as simple markdown files that describe workflows or tools. "

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

" The model was baked and once it’s baked, it does not learn again until they bake a new one. "

" The AI doesn’t train itself; we provide context dynamically, so it enhances answers with curated data. "

" Think of the context window like an intern's briefing document: would the intern be able to answer the question with this information? "

" Evals are really your intellectual property—they define what good looks like in your domain. "

" Today’s best AI products are designed by engineering first, but UX and product people have to join the party. "

" Building evals is like building tests to know if your AI system is good enough, and you can rerun them as models improve. "

" AI in design can act as a creative companion, helping explore ideas and analyze past research more efficiently. "

" Building generative AI tools is not scary, it’s just very different from the last 20 years of building products. "
