Elon Musk and Sam Altman’s talks from YC startup school.

Elon Musk and Sam Altman’s talks from YC startup school.

A lot of scepticism around “prompt engineering” was caused by calling hand-wavy tricks from non-technical folks “engineering”. Context Engineering, on the other hand, is emerging in the context of building testable systems and products to make LLMs useful, aimed at technical folks. As time has passed, “legit” prompt engineering jobs have started looking more like that already, but “context engineering” as a term is a nice Pokémon evolution. - Keshav

This report claims that asking reasoners to “think step by step” only increases costs, not performance. But I think there’s merit to prompting these models elaborately to follow a custom reasoning policy beyond a simple CoT prompt.

Just before WWDC, researchers from Apple released this paper claiming that reasoning models don’t actually reason. But turns out, the models were failing a lot, partially because they weren’t thinking for long enough. I know nothing about research, but we know these models are better. Why not just use them to build a better Siri (which again was missing from WWDC)?

You can just vibe-code agents now. i tested this a couple times and i like the ‘flow’ feature of seeing your code in a workflow/canvas style - next extension of this i’d want to see/use is to edit the canvas ‘actually do it like this’, i also think they should not ask for your ai api keys and just let users use theirs+markup. It’s basically a create/lovable/bolt interface for agents. tbd if it’s the right one (vs ‘canvases’)
