" You can’t just be a designer adapting UX workflows assuming everybody else’s workflow stays the same; everything is changing with AI. "

" Evals define a shared definition of good with tests to measure it, and that is the secret sauce for building great AI products. "

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

" The Rosen Bot is trained on all of our books plus over a thousand recorded sessions from conferences and community talks. "

" Language is hard, and we use anthropomorphic words like reasoning and thinking to describe what the model does technically. "

" This is where UX and product strategy bring huge value—defining what good means rather than leaving it to engineers alone. "

" 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. "

" The product is imperfect, probably about 60 percent there, but if we get to 80 percent it will be a compelling tool for UX content. "

" The Rose Bot has read everything—every piece of Rosenfeld’s knowledge—to help users access it. "
