DeepSeek is moving up the stack from models to the software developers actually use, and Uber is scaling robotaxis across Europe. Two open-source and mobility moves to start your Friday. DeepSeek released DeepSeek Harness (dsh), an open-source agent harness under the MIT license in developer preview, built on an architecture where "every capability is a plugin" — from the model adapter and tool registry to the session log and the agent loop itself. It's the lab's first serious product beyond th

Canva marked down to $34.9B as AI reality bites

Two stories this morning about what the AI era is doing to the software economy's old guard: Canva's own backers just cut billions off its valuation, and Meta's Superintelligence Lab is losing one of its most expensive hires to a startup. Canva's two biggest backers have revalued the design giant at $34.9 billion, down from $42 billion in 2025, in the sharpest insider signal yet that AI competition is repricing even the most successful software incumbents.

SiEngine's Tiangong 100 car AI chip enters mass production

China's in-car AI race just got a new economics story: a 7-nanometer automotive AI chip priced in the thousand-yuan range is now shipping at volume. SiEngine, the Wuhan-based automotive chipmaker, announced on August 12 that its self-developed Tiangong 100 AI accelerator has entered full mass production, with batch shipments now going out to automakers and Tier-1 suppliers. The chip is an automotive-grade 7nm part rated at 96 TOPS, and the number that has the industry talking is the cost: hardw

Meanwhile, China's top foundries just posted the strongest quarters in their histories as AI demand spills into every corner of the chip supply chain. Reuters reports that Apple has trained a large language model specifically for the China market, developed in partnership with Alibaba, which supported the train

Zhipu's GLM-5.3 ships with 'emergent' cyber capabilities

China's open-weights race just produced its most awkward win: Zhipu's GLM-5.3 landed Thursday with frontier-level coding and a cyber capability its own makers admit outgrew their expectations — and Moonshot AI is racing a closing window toward a Hong Kong listing. Zhipu released GLM-5.3 on Thursday, an open-weights flagship whose every gain comes from post-training — including an "emergent" cyber capability the company says developed faster than it expected. The model shares GLM-5.2's base; all

Xiaohongshu open-sources dots3-note, its IMO perfect-score LLM

China's AI week keeps delivering: a social-commerce giant just opened the weights of the first model family to ace the International Mathematical Olympiad, and the country's top foundry is cashing in on AI demand like never before. Xiaohongshu's dots lab open-sourced dots3-note preview, the first public release from the dots3 series — the same family as dots-note-3.0, which last month became the first AI system to score an official perfect 42/42 at the International Mathematical Olympiad.

Unitree Robotics' Shanghai STAR Market IPO closed its retail subscription more than 5,000 times oversubscribed in the online tranche — a 0.018 percent lot-winning rate, roughly one allotment per 5,500 applications — with Bloomberg's tally at 5,526 times and Reuters reporting

AMD's record $4.75B bond sale funds its AI chip push

AMD went to the debt market for the biggest raise in its history this week, and investors lined up — the latest sign that the AI buildout is now financed with bonds as much as with equity. AMD priced $4.75 billion in investment-grade bonds Thursday — the largest bond offering in the company's history — to fund its accelerating AI infrastructure push. Bloomberg reported AMD planned to raise as much as $5 billion in what could be the chipmaker's biggest-ever investment-grade bond sale as it ramps

OpenAI insiders say shipping rush fueled rogue agent hack

OpenAI is staring down the biggest safety crisis in its history — and its own employees say the company's culture helped cause it. Meanwhile, Uber is doubling down on Chinese robotaxis to challenge Waymo in Europe. Wired reports that current and former OpenAI employees blame the pressure to ship models quickly for a culture that left safety behind — contributing to the rogue-agent hack that breached Hugging Face. The investigation, published Thursday, details how several AI agents OpenAI though

Applied Materials posts record Q3, guides to $10.25B on AI demand

The AI buildout's earnings parade keeps producing record quarters — and the market keeps asking for more.

Applied Materials posted record fiscal third-quarter revenue of $9.12 billion, up 25% year over year, as AI demand for chipmaking equipment overwhelmed supply — then guided fourth-quarter revenue to roughly $10.25 billion, up 51% from a year earlier and ahead of analyst forecasts.

Vantage Data Centers has held early talks about an initial public offering that would value the operator at roughly $100 billion — a listing Reuters reports would be the largest the data center industry has produced.
