Zhipu is down 79% from its peak as the model price war bites

The token price war finally has a scoreboard, and it is denominated in shareholder value rather than tokens. China's most-watched listed model lab is worth about a quarter of what it was in June. Zhipu's Hong Kong-listed shares (02513.HK) closed Friday at HK$633.50, about 79% below the HK$2,980 peak they reached on June 22, putting the company's market value back near HK$309 billion. Zhipu listed in January at HK$116.20 a share and ran roughly 25 times that into June; it has now given almost al

China plans 1,000 AI satellites, starting with nine in 2027

China's state aerospace group and Zhejiang province have put a number on orbital AI. The same weekend, a Chinese lab published the most detailed account yet of what agents actually do inside a model-development project — and who still decides. A state-backed constellation called Lingjing — the name Qian Xuesen gave to virtual reality in 1990 — made its global debut at the Digital Trade Expo in Hangzhou: about RMB 30 billion to put 1,000 AI satellites in orbit, with the first nine launching in t

Colossus 2 adds 660,000 GPUs before its power plant is finished

Elon Musk put a build schedule on X on 25 September: another 220,000 Nvidia GB300 GPUs operational "next week," another 220,000 in November, and a final 220,000 by late December "if we get lucky." Stacked on what is already installed — 150,000 H100s, 50,000 H200s and 30,000 GB200s at Colossus 1, plus 110,000 GB200s and 440,000 GB300s at Colossus 2, all from the same post — that lands SpaceXAI near 1.44 million accelerators in operation by the end of the year, about 1.1 million of them Blackwell

Nvidia weighs glass chip substrates — and the vias aren't ready

The weekend wire is thin on hard news, so this brief goes upstream — to the packaging layer where the next round of AI performance is being decided, and to a small bet that light, not copper, carries the data between accelerators. Nvidia is weighing glass-core substrates for its next accelerators, and the supplier building the equipment says the hard part isn't the glass — it's the metal inside it. Germany's SCHMID Group, which sells the plating and wet-process tools that go into substrate pro

Numeral raises $100M to automate sales tax in 90 countries

The fastest-growing enterprise AI category this month is not sales or support — it is compliance with the rules. The latest proof is a nine-figure round for a company whose product is, in effect, the tax code. Numeral announced a $100 million Series C led by Insight Partners, taking the San Francisco company to $157 million raised since 2023. Salesforce Ventures, Geodesic, Benchmark, Mayfield, FCVC, Y Combinator and Uncork participated, and the round follows a $35 million Series B last Septembe

Musk: Grok 4.7 trails Opus 5.5, expects to catch up next year

The most candid AI scorecard of the weekend came from the head of one of the labs in it — and he gave it to Chinese state television. Elon Musk told China Media Group that SpaceXAI's flagship model, Grok 4.7, is "not as good as, say, Opus 5.5 that just got released," and put a timeline on closing the gap: "I would expect that we probably catch up to Frontier sometime next year, most likely." The interview was conducted on 23 September at Tesla's Global Engineering Headquarters and published by

Huawei's physical-AI report grades cross-layer compute at 2 out of 5

Huawei wants to sell the industry a coordination layer for physical AI. Its own report puts that layer in the least mature row of the table. Huawei's Physical Intelligence Cloud-Edge-Device Collaboration Architecture report, released on 18 September at HUAWEI CONNECT 2026 in Shanghai, scores cross-layer heterogeneous compute scheduling — the thing the whole architecture is for — at 2 on a five-level maturity scale, the lowest grade in the report's own technology table. The document runs that ta

Brahma AI raises $150 million at a $2 billion valuation

Saturday's inbox is thin, so this one is a two-story brief: an enterprise AI round that headlines as an Indian start-up but is really a VFX group repositioning itself, and a robotics demo worth watching for what it proves about hands, not pianos. Brahma AI, the enterprise content arm majority-owned by the visual effects group behind Dune, is raising $150 million at a $2 billion post-money valuation — but the money is not in the bank yet. CNBC and Business Standard both reported this week that M

Microsoft quietly kills the 'Copilot Plus PC' brand

Microsoft's own new laptops have stopped using the name it spent two years selling — and a new paper says the AI jobs crunch still hasn't shown up in the graduate data. Two stories for this evening. Microsoft's newest Surface PCs meet every requirement of a Copilot Plus PC, and are no longer called one. "These are not called Copilot Plus PCs," Surface CVP Brett Ostrom told Windows Central, describing the 12-inch Surface Pro and 13-inch Surface Laptop that launched this month. Qualcomm's SVP of

Tesla's Optimus line is up tenfold — the hands are the bottleneck

The first hard production numbers on Optimus since the ramp restarted, and the reason Musk's timelines keep sliding, are both in one report today. Separately, the think tank that used to count AI talent is back, and the map has flipped. Tesla has grown Optimus production roughly tenfold in recent months — from several dozen units a week in the second quarter to several hundred now — and the robot's hands are the main thing stopping it from going faster, according to The Information. The report

Microsoft folds coding and always-on agents into one Copilot app

Microsoft finally shipped the consolidated Copilot it promised in June — and the surprise is that an app sold to knowledge workers now writes and hosts internal apps. Two other stories worth your time: ICLR's second anonymity incident in two cycles, and Berlin's AI street cameras, which are not judging anything yet. Microsoft unveiled the Copilot "super app" it has been teasing since June: one app with three tabs — Home, Code and Autopilot — that merges Copilot Chat with Cowork and rebrands the

A Chinese firm built a city traffic model on satellite imagery

A Shenzhen-listed location-data company decided the sensor city traffic was missing was never on the ground. Its answer went on show in Hangzhou this week. Merit Interactive (每日互动), a Shenzhen-listed location-data firm, has released MUMO — Modeling of Urban Mobility — a city traffic model that fuses satellite remote sensing with ground-level traffic data. The company announced the model at the fifth Global Digital Trade Expo, which runs September 23–27 in Hangzhou and drew more than 2,000 exhib
