We are in a time of technical deflation. That must change how we manage tech debt. https://t.co/Oojkl4XOH3

Day over day, year over year, AI is driving down the cost of writing code. Economists have a word for what happens when stuff keeps getting cheaper: deflation. And you do things…

I’ve been impressed with AI Studio’s Apps for prototyping. https://aistudio.google.com/apps So I decided to give it the ultimate challenge: I pasted in XKCD 1425, and nothing else. I’ll let you be...

We tested one of the most common prompting techniques: giving the AI a persona to make it more accurate We found that telling the AI "you are a great physicist" doesn't make it significantly more accurate at answering physics questions, nor does "you are a lawyer" make it worse.

We tested the classic "You are an expert" technique to see if it would make the models smarter. It did not. They just don't get smarter by telling them that they're smart. (You can, however, make them dumber...) https://t.co/GcnSwpJngJ

My friend @harper is giving coding agents was to collaborate, and they're performing better. I think "social tokens" are a genuinely new thing, as LLMs get value from each others' outputs to solve problems more efficiently.

Yesterday I accidentally ported @steveyegge's "Beads" to Windows. Modern AI is amazing. And Beads now supports Windows. https://t.co/l4ZUyafQ7i

Tuesday, 9:40am, Seattle. Whatsapp buzzed. Harper sent a link – a new project from Steve Yegge that makes AI agents more effective. Worth a try. I opened Codex CLI* in Powershell and…

Some of the most interesting experimentation in AI are people trying to chart a way forward by developing new approaches to doing work based on the strengths and weaknesses of the models we already have. Example: @danshapiro on slot machine deployment:

Great piece by @KyleOrl on our research - classic psychology findings work with LLMs too.

Study shows how patterns in LLM training data can lead to “parahuman” responses.

More coverage of the surprising findings in our research. TL;DR - the same persuasive techniques that work on people, work on AI. https://t.co/zEt6gKzKRc (with my coauthors @emollick , @angeladuckw, @LennartMeincke, Lilach Mollick, and @RobertCialdini)
