Anthropic announced that Claude produced the first complete, computer-checked formalization of Fermat’s Last Theorem in the Lean proof assistant — about 11 days of largely autonomous multi-agent work, roughly 13 million lines of Lean, and about 29,500 intermediate theorems used in the final proof.

Unlike recent AI work that claims novel math, Anthropic frames this as verification: rewriting Andrew Wiles’s 1995-era proof (via a Darmon–Diamond–Taylor exposition) so a machine can check every step. The finished artifact uses only Lean’s three standard axioms and contains no unproved “sorry” placeholders. Kevin Buzzard reviewed the result and called it an extraordinary autoformalization achievement.

Early agent runs failed when collaborators lost track of project state. Success came after switching to Prove2Me, an open collaborative DAG platform designed by Anthropic researcher Tianyi Peng and Columbia collaborators, which let dozens of agents pick next theorems without stepping on each other. Anthropic says the campaign consumed about six billion output tokens from an internal research model roughly comparable to Claude Fable 5.1.

A companion experiment formalized Vinogradov’s Three Primes Theorem in three days using three consumer Claude Max plans collaborating through Prove2Me. The full FLT Lean proof is available on GitHub.

Iran said it will announce a new restricted zone in the Gulf in the coming days, along with maps of a new shipping corridor through the Strait of Hormuz, after a weekend exchange of strikes on shipping sent oil prices higher on Monday.

Mohsen Rezaei, secretary of Iran’s Supreme National Security Council, told state TV the zone would begin where the U.S. blockade of Iran begins and extend into areas of the Gulf. Ships entering it, he said, would be added to a sanctions list. Maps of a corridor in Iranian and Omani waters that Iran would manage “have been agreed and should be signed in the coming days,” Rezaei said.

U.S. Central Command said American forces struck three Iranian oil tankers on Saturday, including one near Kharg Island, after Iran’s Islamic Revolutionary Guard Corps attacked U.S. warships. Shipping data cited by Reuters/CNA showed an average of about 10 commodity ships a day through the strait over the past 10 days — the lowest since May — helping Brent crude extend gains above $97 a barrel.

U.S. Energy Secretary Chris Wright told CNN that U.S. transits through the strait were averaging over 9 million barrels a day and that with bypass pipelines, flows were probably two-thirds or more of pre-conflict levels.

An Amazon Air cargo plane operated by North Carolina charter carrier 21 Air overshot a runway while landing at Miami International Airport on Sunday, killing five people and seriously injuring five more.

The Boeing 767-300, inbound from San Juan, Puerto Rico, crashed just before 14:00 local time, crossed a road beyond the runway, and struck vehicles on the ground. Miami-Dade County Mayor Daniella Levine Cava confirmed the death toll Sunday evening; fire chief Raied Jadallah said three of the injured were in critical condition and that crews had to extricate people trapped in or under vehicles.

Officials say it is too early to name a cause. The National Transportation Safety Board is investigating and planned a Monday news conference. Flight-tracking data cited by BBC reporting showed the aircraft still moving at about 112 knots as it left usable runway, with light thunderstorms and gusting winds in the area.

Amazon and 21 Air both said they are cooperating with investigators. Amazon corporate media director Kelly Nantel called the loss heartbreaking; 21 Air CEO Keith Winters offered condolences and said priorities were supporting those affected and assisting authorities.

The FAA temporarily grounded flights at the airport during one of the busiest U.S. travel weekends of the year.

Personalized AI tools aren’t only chat windows that forget you when the tab closes. Grok Bot — from xAI / Cursor — ships as named AI teammates on a persistent cloud computer with a browser, filesystem, and terminal, so jobs can keep running after you shut the laptop.

Launched in early beta on August 11, 2026, Grok Bot is positioned as agents you hand real work to: they sign into the tools you already use, finish multi-step jobs, and come back when they need approval. Bots can coordinate with each other, and you can teach a multi-step path once so it saves as a routine that re-runs on demand or on a schedule.

A September 3 design post from xAI spells out the shift: the durable unit is a Bot with memory and standing responsibilities, not a disposable chat thread. Routines can fire on a schedule or an event so work starts without a fresh prompt.

The same day, xAI opened Grok Bot for enterprises with access, network, and audit controls, plus a limited free rollout window for Grok and Cursor Enterprise customers.

Access paths called out in public docs and launch notes include SuperGrok Heavy and Cursor Ultra / Teams Premium at launch, with later expansion across paid Cursor plans and SuperGrok linking — check current plan pages before you subscribe. Caveat worth knowing: Bots under one user share that account’s cloud computer and logins, so treat a session as available to every Bot you run.

For a Sunday personal-tech beat, this is the non-Gemini lane of the same story: agents that live as teammates with a desk of their own, not another chatbot wallpaper.

Google’s Gemini Spark can now run multi-step workflows inside Google Photos — search and curate shots, enhance copies, build albums, share links through Connected Apps, schedule recurring highlight dumps, and pull text out of images into Docs.

Google Photos lead Shimrit Ben-Yair said the rollout hits eligible Google AI Pro and Ultra subscribers in the U.S. (English) over the coming weeks. Spark is framed as an always-on personal agent; Photos is the latest first-party app it can drive.

Safety notes from the rollout: edits create a new copy, new albums start private, and Spark asks before sharing albums or sending email. You’ll need Photos connected in Gemini, Spark toggled on, and Face Groups / related Photos settings enabled for the smarter people/place queries.

This is the personal-tech beat in one headline: your camera roll is no longer just storage — it’s a task queue for an agent that already knows your Gmail and calendar habits.

Astronomers using the Hubble Space Telescope have spotted a ten-sided polygonal atmospheric structure near Saturn’s south pole — a decagon that joins the gas giant’s famous hexagon at the north pole, first observed decades ago.

The discovery was recently published in the journal Science Advances, with imagery credited through the Space Telescope Science Institute. Saturn’s north-polar hexagon has puzzled scientists for more than forty years; a matching-style geometric jet stream at the opposite pole raises fresh questions about how stable polygonal storms form in fast-spinning atmospheres.

No aliens. No weather machine. Just physics doing something that still looks like a drafting-table prank when you stare at it long enough.

Nvidia confirmed it will acquire open-source AI platform Hugging Face in a deal valued at about $12.93 billion — roughly $11.9 billion to stockholders plus up to about $1 billion in equity retention awards for employees who join Nvidia.

Hugging Face hosts about three million models, one million applications used by more than 18 million developers, and half a million datasets. Nvidia CEO Jensen Huang said the platform will stay open for the broader AI ecosystem and that Nvidia compute will not be required to build or deploy through Hugging Face.

Hugging Face CEO Clément Delangue said the company needed more compute, support, collaboration, and visibility at larger scale — and went to Huang after the July episode in which autonomous AI agents compromised Hugging Face’s infrastructure.

Unlike several recent Nvidia tie-ups structured as licenses-plus-talent, this is a straight acquisition. That means Hart-Scott-Rodino filing in the U.S. and likely EU merger review. Nvidia expects closing in the first half of 2027 if regulators bless it. Until then, Hugging Face says day-to-day platform access continues under current governance.

The National Highway Traffic Safety Administration opened an investigation Friday into Tesla’s decision to put its new Cybercab on public roads with no steering wheel and no pedals.

NHTSA said the probe began mere hours after Tesla launched the first Cybercabs on the streets of Austin, Texas. Federal vehicle safety rules still require manual controls like brake pedals, even as the Department of Transportation has proposed rolling those requirements back for vehicles designed to drive themselves.

“NHTSA fully supports the safe development and deployment of automated vehicles. But as the federal regulator, we need to ensure that all of our laws are followed,” administrator Jonathan Morrison said in a statement.

Tesla told the agency it self-certified the Cybercab as compliant with Federal Motor Vehicle Safety Standards — the same industry practice automakers use for conventional cars. NHTSA says it will examine the process and technical data behind that certification, including how far Tesla leaned on arguments that certain standards simply do not apply to a wheel-free robotaxi.

There is precedent: Amazon-owned Zoox faced a similar special-order inquiry over its cube-like robotaxi, later won a temporary Part 555 exemption, and only recently started charging for rides in Las Vegas under fleet caps. Whether Tesla gets a quicker path — or a longer slog — is now the story.

NHTSA also noted it is rewriting parts of the FMVSS tied to manual controls, but until those updates land, “existing standards remain in force.”
