New - Billionaire Stanley Druckenmiller tells me "of course" he used AI to write op-ed on Bessent & bond market "There's a reason I moved from an English major to being an economics major," he says, "I'm not embarrassed by it" No response from WSJ notus.org/media/stanley-…↗

One solution is to train the AI to write like you. Specifically: 1. Ask your agent to assemble everything you've ever written. Docs + Slack + X + Other. 2. Then have it write a markdown profile on you, your style and beliefs. 3. Then when it writes, ask it to pull specific word…↗

Super interesting interview. Summary: - Predicts tokens get 10-1000x cheaper and that creates new product categories. sail sells open-source LLM inference at claimed unbeatable price/token + long-running agent sandboxes - The market optimized for chat latency (cursor pulled it…↗

You can go further than this to get even better writing output. Create a little script to analyze your corpus' usage of punctuation, p90 sentence and pargraph length, quotes per 1000 words, comma usage, triplets, negation, etc. (add as many numerical graders as you want). Then co…↗

As the kids in SF say, @dylan522p is only 'directionally correct'. Since no one's done the math, I did: Economics of becoming your own inference provider come down to 4 numbers: 1. Selling price: Kimi K3 charges $15 per 1M output tokens. But in a competitive market, are you rea…↗

Really interesting new blog post from @openai for several reasons: 1) Shows an example of building with WebMCP, meant for when you want agents and and humans to collaborate on using a UI (like co-editing notebook cells). It's different than MCPs or APIs in that its exposed di…↗

ChatGPT Work can now use its computer and browser to sign in to websites on web and mobile, without ChatGPT ever seeing your username or password. That means you can ask it to: • Set up utilities for a new apartment • Book a DMV or passport appointment • Check reimbursement cost…↗

I’m Noah, the founder of Instinct. Instinct is a personal agent that we’ve been building for the past few months. The interface is simple: there are no new interfaces. You can text or call it. It's trained to use a phone and a computer in the same way that humans do. Instinct co…↗

We have conducted a thorough investigation into the Hugging Face incident. We are releasing a technical report and accompanying blog post that reconstruct the agents’ activity, explain why existing safeguards failed, and detail how we’re preventing recurrence. …↗

For the first time, we’ve given external researchers a way to study AI’s impacts using real, privacy-preserved Claude usage data. To date, this work has only been possible within AI labs. We can’t tell the whole story alone, so we opened up our tools. …↗

Give your users a retro handheld game console when they hit a 404 page↗

Music streaming is amazing. You can just play any track ever recorded. But I can never remember what I have saved, so I end up listening to the same stuff all the time. Weird paradox. Anyway, I made a cozy listening room so you can flip through & play your @Spotify albums:↗

i made a game where you literally have to find a missing semicolon in a codebase of 187,421 lines the catch is the entire codebase is printed out and taped to the walls of an office and you have to inspect it line by line Play it here: semicolon.trm.sh↗

Mario (creator of Pi) thinks this video is worth watching. He's smarter than me so he's probably right. (It's about memory in code tools, and it features a crash out at how bad Claude Code's memory is)↗

In June, I left OpenAI after five years as a posttraining researcher and, later, a research manager. I worked on ChatGPT apps, memory, early coding agents, human data, and synthetic data methods. The past couple of months of reflection and exploration have reinforced my convicti…↗
