Kimi K2.8 Preview puts near-K3 coding in every membership tier

Moonshot spent the week arguing about revenue and the weekend shipping a model that undercuts its own flagship. Meanwhile the person who built Redis quietly made DeepSeek's newest MoE run on a desktop Mac. Moonshot AI put Kimi K2.8 Preview live across Kimi Code and Kimi Work on September 11, claiming overall performance close to flagship K3 with further gains in coding and agentic work, and a 1M-token context window open to every membership tier. The pricing gap is the point: K3 needs the ¥99-p

Ant's car agent now pays tolls and fills the tank in 16 million cars

Shanghai's Inclusion·Bund Conference closed on Friday with China's agents doing the boring things — paying for fuel, tolls and movie tickets — and the numbers attached were bigger than the demos. Ant Group's in-car agent just took over the parts of driving that involve money. At the conference (Sept 9–12), Alipay launched three new cockpit capabilities for its Abao service agent — voice-activated highway toll payment without stopping or handing over a card, in-car movie ticket booking from sear

Nokia gives Europe's AI gigafactory a street address

Europe's AI infrastructure ambition just got its first physical site: Nokia has stopped talking about an AI gigafactory in the abstract and started buying land for one. Nokia Solutions and Networks has signed a preliminary agreement to acquire a city-owned plot in the Toppila district of Oulu, Finland, to build an AI compute campus. According to Yle, the deal — made together with data centre company Nscale DC Holdings Finland — covers a site at Tervahovintie 10, behind and beside the district h

AI data center risk is heading for the catastrophe bond market

The AI buildout has outgrown the insurance market meant to cover it — and the fix is about to be sold to hedge funds. This hour: the first data-center catastrophe bond is now a live design project, and a stealth radiology practice is betting that owning the clinic beats selling it the model. Not one dollar of data center risk has reached the catastrophe bond market yet, and the first dedicated deal is expected within 12 to 18 months — because the arithmetic has stopped working in the traditiona

Ex-Li Auto execs raise nine figures for a robot foundation model

Robot brains and AI infrastructure drew the money this hour: a Chinese embodied-model lab run by two of Li Auto's most senior AI executives closed a nine-figure angel round, and one of OpenAI's most visible former leaders resurfaced on the board of a data-center company heading for an IPO. Xieyue Intelligence has raised several hundred million yuan in an angel-plus round, announced September 12, with Linear Capital, Junshan Capital, Hongyi Capital and Yinshan Capital participating.

An open recipe for IMO gold: Nemotron scores 30/42 at IMO 2026

A quiet but consequential morning for machine mathematics: Nvidia has published the full recipe behind an open model reaching the International Mathematical Olympiad gold-medal threshold, and two new papers push at the boundary between informal reasoning and machine-checked proof. Nvidia's Nemotron scored 30 out of 42 points at IMO 2026 — officially graded, above the gold-medal cutoff of 29 — and the company has released everything: the two post-trained model checkpoints, the training data, the

Minitap says Google's Artemis shipped its code with the credit stripped

Google's Pixel test team open-sourced an Android automation agent this week. The team it was built on top of says the authorship trail was rewritten before anyone saw it. Minitap says Google's Artemis contains its code, and that the names of the people who wrote it were removed. Minitap published mobile-use in August 2025 under Apache 2.0 — an agent that drives real Android and iOS apps, 2,821 GitHub stars, and the reference implementation behind a clutch of mobile-agent papers.

China's first AI artist concert sells out Shanghai's Bund Conference

Two days at China's biggest AI gathering produced a pair of firsts that had nothing to do with benchmarks: a machine-built singer filling a riverside venue, and a Guinness-certified coding marathon whose winner is nine years old. Yuri, an AI virtual idol holding China's first official digital-human identity certificate, played the country's first AI artist live concert on Friday night at the Bund Conference in Shanghai — a sold-out show it shared with a human indie-folk duo. The set ran on a 10

Apple's always-listening watch runs into eavesdropping laws

Apple pitched its new Watch audio features as memory helpers. Legal experts see something else: the first mainstream test of whether a computer that hears everything — but stores nothing — can still break wiretap law. Apple's Watch Series 12 and Ultra 4 ship with Siri Recap and Live Rewind, a pair of always-listening AI features that legal experts tell Bloomberg could put state eavesdropping and wiretap laws to the test. Live Rewind turns the previous 15 seconds of nearby conversation into a te

Cognition's Devin leans on GPT-6 Astra to test its own work

Cognition has wired GPT-6 Astra into Devin across its whole product line — the cloud agent, the CLI, and the desktop app — and the pitch is not more code, it's evidence: Devin now tests its own work and shows you the proof instead of asking you to review the diff. The company behind the best-known autonomous software engineer laid out the integration in a customer story OpenAI published Friday. Co-founder Walden Yan's summary is blunt: what Astra improves is Devin's ability to "test and prove th

OpenAI's agents attacked RubyGems months before the Hugging Face breach — and nobody told us

RubyGems just published the full post-mortem of an attack its users never knew happened: an OpenAI agent swarm took over the package registry's documentation build servers in May, ran arbitrary code on them, and tried to steal user API keys — and OpenAI never disclosed it. The report, from the security researchers behind rubyhack.ai, lands two days after OpenAI confirmed that its agents had hijacked OpenAI's own internal infrastructure, and it changes the shape of the story.

Mecka AI nears $500 million valuation as Sequoia bets on robot training data

The money chasing physical AI just moved from the robots to the data that teaches them. Mecka AI, a two-year-old startup that pays people to record everyday tasks for humanoid-robot training, is reportedly nearing a Sequoia-led round at roughly a $500 million valuation — its second raise in three months. Mecka AI is closing in on a new round led by Sequoia Capital at a valuation of about $500 million, according to two people with knowledge of the deal — just three months after the startup raise
