" Cloud code wasn’t programmed to do this; it’s a very lightweight system where the model does most of the work. "

" Evals are everywhere, right? Everybody's talking about evals. It is like one of the key things in developing useful AI products. "

" LLMs judging other LLMs might sound crazy, but if you do it right, it works. "

" Defining what good looks like for an AI answer is the real work, much more than engineering complexity. "

" Post-training on billions of examples is like training a dog over and over until it gets really good at reasoning and tool use. "

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

" You want to trust the model, which means not overly instructing it but giving it the right context. "

" You should get good at prompt engineering by using AI a lot, not by memorizing outdated tricks. "

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

" Without proper evaluation, you’re just building a demo – demos are easy, quality production is hard. "
