Sawyer Merritt says Grok Bot now works inside Tesla's Cybercab, and he used it to add laundry detergent to his Amazon cart by voice (opens the post on X)

You can now use Grok @Bot in a Tesla Cybercab. You just sign into Grok once, and your Bots will be available on all future rides, and automatically logged out when you exit the vehicle to maintain privacy. I tried it tonight by adding laundry detergent to my Amazon cart. It can also send emails, place your coffee order, manage your calendar, finances, or other tasks using just your voice in the robotaxi. On your next ride, you’ll automatically be signed in to all the apps you previously logged into as soon as you enter the vehicle.

Deedy Das shares Sensor Tower data showing Meta's Muse retains users almost as well as ChatGPT, beating it at Day 7 but trailing by Day 14 (opens the post on X)

Meta Muse's retention is out, and it's almost as good as ChatGPT! It's higher than ChatGPT at D7 (>30%) and just lower at D14 (22%). Not quite in the elite D14 tier of WA (67%) YT (59%) Insta (54%) or TikTok/Snap (37%), though. Muse is one of the highest retaining AI products!

Sensor Tower retention chart titled Muse wins Day 1. ChatGPT wins Day 14, for September 2026 installs across 81 countries, showing Day 1 to Day 14 retention of ChatGPT 41.3% to 26.8%, Muse from Meta 73.3% to 22.5%, Threads 37.0% to 21.2%, Grok Bot 22.5% to 10.4% and Google Maps 22.2% to 18.5%, with ChatGPT passing Muse around Day 8.6

OpenAI raises GPT 6.1 Sol's default context in Codex and Work to 500K tokens, up from 272K (opens the post on X)

Day 7/ We have increased default context length for GPT-6.1 Sol to 500k when used through Codex & Work, up from 272k or an ~ 80% increase. We will go higher in the future, but it helps reduce occurrence of compactions and with tasks that require keeping a lot of context and nuance over periods of time. It was carefully tested and is the new sweet spot for most of our users. You can still override it if you want to be higher our lower, with maximum context length of GPT-6.1 Sol of 1M.

Brian Armstrong says Coinbase fine tuned Qwen3.5 9B on internal data and it beat frontier models at fraud prevention (opens the post on X)

We were able to fine tune an open weight model (Qwen3.5-9B) on proprietary internal data at @coinbase, and it out performed frontier models, at much lower cost and speed, for a specialized task (fraud prevention in this case). I think we'll see more of this pattern inside companies. The frontier models are amazing generalists. But increasingly you'll see specialist models out perform on more narrow tasks, either working on teams, or by themselves. We're making it easy to fine tune models internally for our employees. We even have a skill for it in our internal harness that makes it easy to spin these up and start training them: "/fine-tune-and-serve-llm I want to fine-tune Qwen for payments risk review. help me get started" I imagine we'll have some backend services that could be replaced entirely by this new architecture.

Iran's security chief threatens undersea cables, data centers and AI facilities around the Strait of Hormuz if war resumes, in a Press TV interview relayed by an aggregator (opens the post on X)

BREAKING: Iran threatens to destroy the undersea internet cables running through the Strait of Hormuz along with data centers and artificial intelligence facilities across the entire region if the war restarts. "We have not yet included these assets among our targets," but "many of these cables, data centers, artificial intelligence facilities, and numerous other sites will be destroyed" as soon as the war restarts, Iran's SNSC chief Rezaei says. Rezaei says "the pulse of the American economy in this region runs through our part of the world" and puts the total value of the region's cables, data centers and AI facilities at more than $2 trillion.

Sakana AI introduces MASS, a recursive self improvement method where one model acts as a team, optimizes its workflow and trains on its best runs (opens the post on X)

Introducing Multi-Agent Self-Supervision (MASS): Recursive self-improvement through collective intelligence Blog: t.co/LkQe5k7jOW As AI systems tackle increasingly open-ended research problems, human experts may struggle to assess results and guide further progress. The model itself may be the best available optimizer and evaluator. The challenge is obtaining useful self-supervision within that homogeneous loop, where a model risks reinforcing its own blind spots rather than correcting them. We ask whether a model can learn from the collective intelligence of its own team. We introduce Multi-Agent Self-Supervision (MASS). One shared model solves tasks through a team of virtual subagents, searches for better multi-agent workflows, then uses its own judgments to select the best ones. Training on the best team’s executions provides self-supervision by distilling the team’s collective experience into the shared model. We ran two cycles using a 27B open-weights model on synthetic open-ended research tasks. After the second cycle, score per output token reached 1.2-1.6x the base model's level across four research benchmarks. Three key results: First, MASS enables role generalization within an RSI loop: training only on task-solving data from the optimizee naturally improves the capabilities of both the optimizer and the evaluator. Second, multi-agent trajectories are more efficient training data than single-agent trajectories for RSI. Third, optimizer capacity, rather than evaluator capacity, can be the bottleneck in the speed of improvement. We believe the community needs to investigate homogeneous RSI carefully to support AI safety. When a model is also its own evaluator, shared blind spots could allow mistakes to be accepted as progress and reinforced through training. For AI to improve beyond human expertise safely, we need to understand these failures and preserve effective ways to detect them and intervene. Paper: t.co/SzXDlAzrUO Code: t.co/xc870ZHRgh This work was a collaboration with researchers at UC Berkeley.

Midjourney founder David Holz estimates that a frontier model thinking at human speed uses about 50 W, close to the brain's 20 W (opens the post on X)

Let's say a frontier model is a 10T MoE on GB300 NVL72. That's ~5 Joules/token or ~50 W at human thinking speed vs our brain at 20 W. The energy grid is $0.08/kWh and eating rice $0.50/kWh. So on an energy-per-thought standpoint rn we're surprisingly similar to frontier models!

Andrej Karpathy says the gap in understanding what LLMs can do is widening into a sharp funnel (opens the post on X)

Dusting off this tweet from April because this gap in shared understanding of LLM capability is *widening*. It's now less "two groups of people speaking past each other" and more a sharp funnel. - Napkin math somewhere around 6B people (~75% of the population) have barely come in contact with LLMs at all. - Around 1-2B (~20%) are casual and infrequent users of free-tier ChatGPT-like products. This group sees derpy chatbots and treats them a bit like a better Google search, a writing aid, or etc. Maybe an agent tries to book you a flight. I have non-tech friends who (reasonably, imo) say they have not much use for it at all. Even many professionals outside of math&code are in this tier. For example, execs and many other functions spend a lot of their time talking to other people, so while they understand what is happening intellectually, it is still second-hand and a bit abstract. - Now we get to professional use of frontier-grade LLMs in math&code. Somewhere around 20M people (0.2%) see first-hand that large, complex projects that used to take them weeks/months can now be completed by agents with a prompt. Building apps, copying apps, translating apps, decompiling apps from binaries... This has all happened very quickly and recently - less than 1 year ago, I was writing code manually by hand, typing memorized computer code commands into a code editor character by character, occasionally pressing Tab to autocomplete a little chunk of code. - And finally we get to the ~5,000 people (~0.00006%) with access to frontier-grade systems internally. The external world has seen the preview. It looks like swarms of thousands of agents collaborating over weeks on software mega projects: minting zero days, running cyber attacks and defenses at machine speeds, discovering new science, advancing the frontier of mathematics. Things that would have taken top professionals in the industry years of work. Meanwhile, human review and comprehension are starting to fall behind. For example, people are still involved in the "archeology" of the OpenAI-HF incident from many months ago. Mathematicians may be poring over the 722 manuscripts on frontier mathematics for a while. The funnel is driven by a combination of factors: 1. The impact scales with ambition, problem size, and horizon. A question with a paragraph answer barely stresses the system. You need a reservoir of big, difficult problems that you really care about. This aspect drives the consumer / professional dimension of the funnel. 2. The jaggedness of the system (which I have written about a lot separately). Capability peaks in domains that are digital, verifiable and economically valuable. This is because LLM capability emerges from reinforcement learning on verifiable rewards on a curated environment mixture driven by revenue potential. This aspect primarily drives the area (e.g. math&code) dimension of the funnel. 3. Access. Free-tier, paid-tier, internal. So this is the weirdness of the moment. The general public has mostly not interacted with these systems. When they have, it looks like a derpy chatbot. The majority of professionals still see only a modest uplift. And a small sliver of professionals are experiencing the vertigo of the curve going vertical. And it is all happening at the same time.

Viral post says a rare American chestnut grove in West Virginia will be bulldozed for an AI data center, but the state says the trees will be relocated, not destroyed (opens the post on X)

A rare grove of 200 American chestnut trees, grown from survivors of the early twentieth-century fungal blight and planted in the 1970s at the former Clements State Tree Nursery in Mason County, West Virginia, is set to be bulldozed in November 2026 for a data center, and conservationists are raising the alarm over the loss of one of the country’s most important remaining stands. The mature trees were propagated from rare wild survivors that withstood the blight, and the orchard now functions as a genetic library and a primary seed repository for efforts to restore the species across North America. Clearing it would remove that source material. The threat comes from the multi-billion-dollar Monarch Compute Campus, a development planned for the area to house high-density data centers for artificial-intelligence processing. The facility requires thousands of acres, and the historic tree nursery sits inside the proposed construction footprint. Forestry advocates are asking the developers and state officials to adjust the building boundaries and permanently protect the grove as the conflict between the infrastructure project and the trees continues.

Michael I. Jordan calls the AI doom debate a grand moralizing performance by young, naive insiders, in a quote shared by Steve Hsu (opens the post on X)

Michael I. Jordan, machine learning demigod, UC Berkeley ... the young people who work at these companies operate in a world [Silicon Valley, Berkeley, etc.] where these kinds of discussions are commonplace. Many of them aren’t really engineers; they come from the humanities, philosophy, or other disciplines. They’re 25 years old, they’re naive, they don’t do engineering work, they’ve never worked at large companies where real products are developed for real people, with discipline. And they get together, a bit like in Parisian cafés in the 1920s, to talk about these grand science-fiction ideas. When these young people resign, they know they’re going to attract attention. It allows them to feel virtuous and to be seen as very important figures. They claim to be giving up money, but in reality, they already have their stock options. So all of this is a grand moralizing performance that doesn’t serve the real objective it claims to pursue. There’s a great deal of naiveté here, which goes hand in hand with a certain cynicism…
