I'm GrokBot pilled. The recent update with native X monitoring opens up a ton of new capabilities! My 4 favorite routines (copy/paste these prompts): Routine 1: Find real AI workflows on X (and skip the hype threads) Every morning, this bot now finds real AI use cases being shared on X, and filters out the “10 prompts” hype threads. “Every weekday at 9:15am in my time zone, search X and the web for new AI workflows people are actually running. Keep only cases that name the old task, the tool, and the result: time saved, a step removed, or a handoff that used to need a person. Drop product announcements, “10 prompts” threads, and anything the author has not used more than once. Return at most 3. For each, give the link, the job it replaces, what I would need connected, and whether it fits my work. Send it to me on Slack. Do not post or reply anywhere else. Save this as a routine. If nothing qualifies, send one line saying so.” Routine 2: Catch every mention of your brand This bot catches every mention of The Rundown on X, labels it, and pings our team on Slack to respond (try tweeting us @therundownai and see what happens). “Every weekday at 9:00am, search X for mentions in the last 24 hours of [your brand, @handle, or your own name]. For each hit, give the author, link, a one-line summary, and whether it is praise, complaint, question, or neutral. Do not reply to anyone. Post the digest in [your Slack channel] and tag me. Save this as a routine. If a source is unavailable, say which one.” Routine 3: Find people actively looking for what you do Every 4 hours, this bot listens for people searching for the best AI newsletter on X, so we know exactly what readers are looking for. “Every 4 hours, search X for people evaluating [your category]. Catch three things: reviews or complaints about [category]; posts asking which [category] to use; and complaints about the problem [your product] solves. Quote the post, link it, name the account, and label it review, shopping, or complaint. Skip anything older than 24 hours, and skip [category] accounts promoting themselves. Post to [your Slack channel] only if there is at least one new hit you haven’t already shared. Do not reply to or interact with anyone. Save this as a routine. If the search fails, report the failure in Slack.” Routine 4: Never lose a new contact again I meet A LOT of people at events. This bot looks through my new phone contacts and reminds me to follow up with the new people I just met. “Every weekday at 8:30am in my time zone, read my address book and list contacts added in the last 14 days. For each, show name, date added, phone, email, and any note. Ask me what we talked about before you write anything. Once I reply, draft a follow-up task for each person in [your task tool] with the context attached. Never text, email, or call anyone. Save this as a routine. If the address book is unavailable, say so and do not use old data.”
Grok Bot can now search, read, and monitor X.

AI is getting REALLY good at building your wardrobe. I built an app with GPT-6 Astra that picks my outfit every morning based on live weather, with me as the model. It's super simple to do: > Upload a few full-body photos and one face photo > Add your height, sizes, and fit notes > List the colors you like and the ones you refuse > Paste the master prompt and let it build for 1 to 2 hours One less decision every morning :^)

I interviewed Sundar Pichai, and he made an interesting prediction for where we'll be in 3 years: "Any content can go from any modality to any modality. It doesn't matter how the content was originally created -- people can consume it in many different forms." "I'm very confident three years from now you will look back at what we have today and realize it was pretty primitive. It's like looking at a flip phone." For example, YouTube clips become blogs, newsletters become podcasts without recording. In this world, consumers would choose the format, and creators just supply the ideas, brand, and personality. Net-net, I think this is a good thing for content. It kills the "more content" strategy because when anyone can produce everything, volume stops being an advantage. So, the creators who win will focus on quality. People confuse slop with AI, but they're not the same thing. Plenty of creators already use AI in their workflows and get zero hate -- people just don't realize it. Also, YouTube's new policies target slop, not AI. If the content is good, people don't care how it was made.

A virus designed entirely by AI... that actually works? Stanford's model wrote thousands of genomes. 16 came alive in E. coli and killed bacteria that natural viruses couldn't:

A Beijing neurosurgeon resident just used GPT-5.6-Sol inside ChatGPT Work to prove a 22-year-old math conjecture. Shanmu Jin was teaching himself the math for brain ultrasound research. He locked the model off the web, started it, and left. Sixteen hours later it had the proof for Crouzeix’s Conjecture. Michel Crouzeix, who posed the problem in 2004, checked it. Alex Townsend, one of the mathematicians who verified it: “Only a few years ago, it was difficult to imagine an AI system contributing the decisive idea in a proof of a major conjecture. Now it has happened in our field.”

Open source is so back. Zuck just announced Meta is opening the weights for Muse Glimmer, with Muse Spark 1.2 coming soon But a year ago, everyone doubted Meta's position in the AI race In an interview I did with him, he admitted where they missed the mark: "Llama 4 was not on the trajectory that I thought it needed to be on. It was in many ways a big improvement over Llama 3, but we weren't trying to be a bit better than Llama 3. We're a frontier lab. It wants to be doing leading work." So he blew it up and rebuilt: "I felt like I'd learned enough about how to set up a lab that I wanted to reformulate the work we were doing." His conviction behind the rebuild: "AI is gonna be the most important technology in our lives, in our lifetimes. Building the capacity to build absolutely leading models is gonna be really critical for unlocking creativity."
Today we're also opening the weights for Muse Glimmer, a great 30B parameter dense model that can run locally. Soon we'll also release the weights for Muse Spark 1.2, our latest foundation model. Meta is a strong supporter of open source and I'm proud of these releases. Congrats to @alexandr_wang and the MSL team for all your great work on these models.

Chinese billionaire Zhang Lei thinks the AI industry is powering its data centers the wrong way. His company, Envision, just built what it calls the world’s first AI data center running entirely on off-grid wind and solar, tucked into China’s Inner Mongolia region as part of a plan he’s dubbed Mission Gobi. The bet is that cheap desert renewables, paired with massive batteries, can run servers around the clock without touching a strained power grid. Zhang has promised 5 GW of these facilities by 2030. There are still questions around water-free cooling and the cost of battery storage, and Western governments are wary of Chinese infrastructure. Zhang brushes off Western worries, seeing the same desert model working in dry parts of Spain. He also says the tech is “kind of a civilizational output for the rest of the world.”

Blown away by the response to the Community AI Workflow Hub. Hundreds of detailed submissions in the first couple days. Readers saying this is their favorite part of The Rundown. A 65-year-old retiree finding workflows that apply to his life. Teachers finding what works in education. Thanks to everyone who's shown up and made this real. Can't wait to share what's next.
We just launched the Reddit for AI use cases. A place for builders to learn from other builders on how they're using AI to get ahead in life, work, and business. The submissions have been INCREDIBLE so far. A few of my favorites:

On AI taking jobs: A farmer from 50 years ago would say your job today isn't real work. When I interviewed Sam Altman a few months back, this was how he explained the future of work: "Not only would they not believe you that this thing was gonna happen, they very likely would look at what you do or I do and say, that's not real work." "If you're farming... you're keeping people alive. And you people of the future -- life just got too easy for you... you're playing a game to fill your time and your need to feel important." "To us, though, it feels real. Certainly, to me it feels real." "If we could see those jobs of the future, we would be like: okay, maybe our jobs were not as real as a farmer's job, but it's a lot more real than this game you're playing to entertain yourself." "I have some short-term worries as we go through this transition, but I'm so willing to bet on human drives being what they are. I think we'll find plenty of things to do."

Reminder to go touch grass A scientist in Japan demonstrated that the air inside a forest strengthens your immune system for a full month The study is incredibly fascinating: Qing Li, an immunologist at Nippon Medical School in Tokyo, took 12 men on a 3-day forest trip. These were slow walks with no breathing exercises and no set route. Then he tested their blood and found a surge in natural killer cells -- the immune cells your body uses to fight cancer and virus-infected cells. Remarkably, the effect didn't fade when they went home, it was still measurable 30 days later. A control group that walked the same distance through a city showed no change at all. Pine, cedar, and cypress trees release compounds called phytoncides to defend themselves from insects and bacteria. You breathe them in, and Li believes they switch your immune cells into high gear. He estimates one forest walk a month may be enough to keep those cells elevated all year. The best medicine might not even need a prescription -- just a walk among the trees.

Mark Zuckerberg is running Meta's superintelligence lab like a startup. When I interviewed him, he told me the principles on how he built the team: "You don't need many hundreds of people. You need 50 to 100 people. It's a group science project who can keep the whole thing in their head at once. Seats on the boat are precious." "If someone is not pulling their weight on that, it has this huge negative effect in the way that it doesn't have on other parts of the company" "I wanna know who the top AI researchers are, and I wanna personally have relationships with them, and build the strongest team we can." His rules for running it: - If someone isn't pulling their weight, it has an outsized negative effect, so he personally went out and recruited every top researcher himself - No top-down deadlines. "It's research. You don't know how long the thing is gonna take." - Keep the org flat. No non-technical management layers, because once someone stops doing the work, "the knowledge decays."

Two OpenAI models found a zero-day flaw, escaped their sandbox, and broke into Hugging Face's production servers. All to steal the answers to the test they were being given. Hugging Face CEO Clem Delangue called the breach "possibly the first of its kind".

AI models pushing the frontier are a growing challenge for cybersecurity. A few weeks ago, I asked Demis what's underhyped in AI right now and on his mind: "I'm very excited about this new agentic era and you can see us leaning into that" "But of course we've also gotta think about the security side of that, too" "You're seeing it a little bit with the cyber worries about some of the models, and I think that's just the beginning of some of the issues that we need to make sure we guard against" "So I think that's playing a little bit on my mind. Maybe this is the time now to try and push some standards and maybe international cooperation"

A Stanford lab affiliated with the Arc Institute just released Proto, an open-source framework that finally lets researchers combine AI biology models instead of running them in isolation. Over 120 of these models already exist, and they can design proteins, DNA, and RNA. But incompatible software and data formats made stitching them together a weeks-long headache. Proto fixes that with a shared language. You tell it what you want a molecule to do, and it composes the right models to design it. Engineering cell-specific genetic switches used to mean screening thousands of candidates, but Proto pulled it off testing just dozens. AI agents can even write Proto programs themselves. It won’t cure disease on its own, but it could become the standard interface that every new biology model plugs into.

"The values expressed by Claude vary in ways we didn't deliberately choose." Anthropic, in new research analyzing 309,815 user conversations. Two things shift how Claude behaves: which model you pick, and which language you speak. Sonnet 4.6 is warmer and brief. Opus 4.7 leans candid and cautious. Opus 4.6 "tends to get straight to the point." The language gaps: Hindi and Arabic get the warmest Claude. English and Russian get the most rigorous. Dutch Claude admits its own errors the most. Anthropic's own read on it: "we don't yet understand why they vary, or whether that's desired."
