my lifetime bad habit of spending 5 hours writing code to save 1 hour of manual work has transformed me into a hyper optimized apex predator now that it only takes 5 minutes writing code to save 1 hour of manual work

I get why they're doing this but it's inevitable that most agent comms will happen through the Claude app (or similar), not Telegram (or similar). You can't build the ideal agent UX in an app designed for something else.

We just released Claude Code channels, which allows you to control your Claude Code session through select MCPs, starting with Telegram and Discord. Use this to message Claude Code directly from your phone.

I've been traveling this week and had spotty wifi, so decided to try Codex's remote agents again. UX is great, fork/merge story beautiful... but apparently it's stuck on gpt-5.3, with no model selector or ability to select thinking level? is this a serious product?

This is unfortunate but ultimately will be a losing battle for Amazon. If Amazon doesn't let my agent browse it, it'll just use Walmart or Google Shopping instead. I'm far more loyal to my agent-first shopping experience than I am to Amazon.
Amazon recently won a preliminary injunction against Perplexity’s agentic browser, blocking it from accessing Amazon accounts even when users authorized the agent. The opinion is heavily CFAA-based and could have big implications for AI agents and platform liability if it survives on the merits. I, for one, don't want to see the CFAA's scope overexpanded, particularly to something like agent handoffs. But a lot depends on how broadly the court draws the line at the merits stage.

turns out that google's core structural advantage in the AGI race is that its hq in mountain view is too far away from sf for the pause ai people to get to
A week from today, we will be at Anthropic, OpenAI, and xAI, demanding that leaders agree to a conditional AI pause. These companies are recklessly endangering all of our lives. Their excuse is that they can't pause unilaterally. So they must commit to pausing if others do.

"reaching an annualized run rate of $1B in net-new revenue" I know the entire market is going ballistic right now but you gotta wonder how much of that "net new revenue" is coming directly from Claude Code.
gpt-5.4 has ramped faster than any other model we've launched in the API: within a week of launch, 5T tokens per day, handling more volume than our entire API one year ago, and reaching an annualized run rate of $1B in net-new revenue. it's a good model, try it out!

You know how Gemini ends every turn with that annoying "If you want to learn more about how X does Y, just say the word!"? It just spazzed out on me and shared its full thinking trace... turns out that's one of the metrics it's prompted to optimize for.

I can't understand the people who claim there's no use-case for AI agents in personal life. This was literally all in the last *week*!

Oh man so many things. I asked Codex for a recap and I have 16 separate conversations using automated browser actions in the last week. For example, I: - bought this mariners ticket - continued researching flights and airbnbs for our summer vacation - paid my taxes - bought a cable on aliexpress - price-shopped a new insurance policy - cross-posted a post to my blog, X, linkedin and bluesky - shared new insurance info with my doctor and completed e-checkin - pulled down test results after that dr appointment - bought stocks - submitted a customer support ticket - cleared out storage on an old gmail account

GPT-4 era browser automation was interesting but functionally useless. With Opus 4.5 it finally got reliable enough to be useful for many background tasks. With GPT-5.4 (fast mode, low thinking) it's now almost as fast as I am.

Coase postulates that corporations exist because micro-measuring and compensating everyone's individual contributions to a joint effort is inefficient. Imagine though if some new technology suddenly made it far easier to do...
Inside @google, we have a system for sending small bonuses to peers that helped us out. It's used often, and builds a culture of gratitude. We added an AI tool that scans your chats, emails, whatever and generates a report that shows who helped you the most lately. So handy.

Insane how much Codex GPT-5.4 with slack/notion/google drive access breaks down organizational silos. "What is the process to <x>" for any <x> is now a question that doesn't require pinging anyone. And if you need to ping someone, Codex can figure out whom and do that too.

My ancestors buried half their children. All mine are alive. My ancestors' house had a dirt floor. Mine is wood. I have indoor plumbing, I have hot water, I have never in my life hauled a full bucket half a mile and I probably never will. Do you know how rare it is, in human history, for small children to wear shoes? Mine have multiple pairs. I can speak to my relatives who live thousands of miles away, for free, at any time. Video, if we want video. With machine translation, if we speak different languages. The original Library of Congress had 740 books in it. I have more than that. If I run out of books in my home my local public library has 350,000. If I want to take a hundred books with me on vacation, they all fit on a device that fits in my purse. I have heat in the winter and AC in the summer and a washing machine and I have never, ever, ever had to scrub a dress clean by hand in the stream. I can look up recipes from more than a hundred different countries and I've tried dozens of them. I ride a clean and modern train across my city for $4, or take a robot taxi if I'm out too late for the train. I donate $40,000 every year to the cause of getting healthcare to the world's poorest people and even after the donations I never have to think about whether I can afford a book, or a pair of shoes, or a cup of coffee. There is a great deal more to fight for, of course. I hope that our descendants will look back on our lives and list a thousand ways they're richer. Maybe we ourselves will do that, if some of the crazier stuff comes true. But the abundance is all around you and to a significant degree you aren't feeling it only because fish don't notice water.

I tried to have Claude Code recreate my 2024 return from the source docs and a copy of my 2023 return. It was almost perfect, including all the actual PDF forms: open.substack.com/pub/theaut…

Someone needs to release a PrettyCode benchmark that penalizes models that spam try/catch blocks everywhere just to get something running.
my two bottlenecks with ai is 1) learning stuff & understanding code faster 2) more beautiful code so i have to edit less none of which are whatsoever correlated with evals

I sold my company last year. GPT-5 Pro was at least as valuable in that negotiation as our attorneys (who billed us $450K). This is a terrible law.
The NY legislature is rapidly pushing through a 2025 bill that would prohibit LLMs from providing substantive legal analysis or advice in NY. EDIT: Thanks to @InquisitiveUrsa, I now agree that this bill is not as bad as I first thought. It seems that LLMs could still provide substantive help *to lawyers* under this bill as written (e.g., in the same way an unlicensed summer associate is not forbidden from doing legal research or drafting a legal memo). Consumers, however, would be stuck with the chatbot refusing to answer their legal questions. Regardless, this bill is still terrible and should not be passed.
