## Thomson Reuters builds its own legal AI instead of renting from OpenAI

Thomson Reuters builds its own legal AI instead of renting from OpenAI Thomson Reuters launched "Thomson," its first in-house language model for legal work — built on Alibaba's open Qwen rather than fine-tuning a frontier model from OpenAI or Anthropic, a bet on owning AI instead of renting it. The company says it spent about $40 million over two years on the project (the final training run alone came to roughly $450,000). Thomson starts from Alibaba's Qwen — most recently Qwen3.5-397B — which

Nvidia in talks to invest in Perplexity at $30B-plus valuation

The funding treadmill keeps spinning, and Nvidia keeps footing the bill. This time the check is reportedly headed to Perplexity, the AI search upstart that has quietly turned itself into one of the sector's fastest-growing revenue stories. Nvidia is negotiating an investment in Perplexity at a valuation above $30 billion — more than 50 percent higher than the company's last funding round a year ago — according to a report from The Information. Perplexity's annualized revenue has tripled from $2

Anthropic's Opus 5 overtakes flagship Fable 5 as buyers trade down

Anthropic's pricing problem is now official: the company's cheapest new frontier model is beating its most expensive one in corporate wallets, less than a month after launch — awkward timing for a $2 trillion IPO. Opus 5, released July 24 at a fraction of Fable 5's price, has overtaken the flagship in business spending within roughly a month, according to Financial Times reporting on Ramp data covering some 70,000 companies. Spending on Fable 5 has plateaued at around 11 percent of overall outl

China's robot chiefs say big models are still in the 'dial-up era'

At the World Robot Conference in Beijing, the founders actually shipping robots — UBTech, Robot Era, Booster Robotics, Jushen Technology and JD's robotics arm among them — delivered a rare public reality check: embodied AI's bottleneck is no longer demos, it's reliability, manufacturing standards, and cold ROI math. The consensus: chase the boring, high-demand industrial jobs first. Robotics veteran Wang Tianmiao put the question bluntly at a WRC 2026 roundtable: if large models are still in th

Security guard, teen and father-son duo beat 37,000 at TRAE's AI contest

A former security guard who says he can't speak English, a high-school junior, and a father-son pair took three of the top prizes at ByteDance's TRAE AI creativity contest in Shanghai — beating roughly 37,000 entrants with apps built almost entirely by describing what they wanted. The grand prize went to "Token Genesis" (词元开物), a team of first-time hardware founders who built an AI workbench plus a desktop circuit-board mill: type "make me a music keyboard," and the system drafts the spec, picks

Hugging Face explores a sale at a $13B valuation

Two Sunday stories about who gets to own AI's plumbing: the open-source model hub everyone relies on is quietly shopping itself, and Sam Altman is warning that fear could hand AI to a handful of powerful players. Hugging Face is exploring a sale that could value the open-source AI hub at $13 billion or more. Business Insider reports the company has brought in a bank to sound out potential buyers; talks are early and no bidder has been named. It would be a striking turn for a company that raised

Wondershare's Filmora.TV brings the AI canvas to TV ad production

Chinese creative-software veteran Wondershare just pointed its AI video stack at the most expensive corner of advertising: the TV commercial. Wondershare has launched Filmora.TV globally — an AI-native canvas workspace built for TVC (commercial) production teams, unveiled alongside a brand film created for Chinese tea chain Chayan Yuese. Built on the company's widely used Filmora video editor, the product chains the entire commercial pipeline into one infinite canvas: parse a client brief, gene

Kling AI's revenue jumps 200% as Kuaishou's core business stalls

Kuaishou's latest earnings painted a brutally split picture: its legacy video, livestreaming, and e-commerce lines barely grew, while its video-generation model Kling AI carried the quarter as the company's only real growth engine. Kling AI's single-quarter revenue surged past 200% year over year, landing at 850 million yuan in Q2 — the firm's clearest sign yet that its AI bet is paying off commercially. Kuaishou said Kling AI booked 850 million yuan ($119 million) in second-quarter revenue, u

China's AI leap traces back to one Tsinghua lab

A single university lab underpins the two rival forces leading China's push toward the frontier — and the mainland's humanoid-robot boom is quietly reshaping its own venture hierarchy. China's AI leap traces back to one Tsinghua lab. A Wall Street Journal feature traces the parallel careers of Z.ai's Tang Jie and Moonshot AI's Yang Zhilin — teacher and pupil at Tsinghua roughly a decade ago — to argue that China's arrival at the frontier is no sudden development. Both found early footing in the

Deep Dive — Nvidia's $6 billion plan to beat China at open weights

For a company that historically made its money selling the shovels, Nvidia just bought a pickaxe. The chip giant is taking the extraordinary step of licensing the model-building software of the Paris startup Poolside and hiring 109 of the people who used it — a deal people familiar with the matter say Nvidia intends to turn into one of the world's most powerful open-weight AI models, built specifically to answer Chinese heavyweights like DeepSeek and Kimi K3. The number attached to that ambition

Alibaba proposes $10B share placement to fund an all-in AI push

The clearest signal yet that Chinese tech is going all-in on AI came from Alibaba's boardroom this morning: a proposed Hong Kong share placement worth roughly US$10 billion (about HK$80 billion), with essentially all of the proceeds earmarked for artificial intelligence. It lands in the same week the company told investors that its latest quarterly net income fell about 75 percent year over year — because it was spending so hard on AI infrastructure.

Agibot-controlled Swancor opens orders for Qiyuan Q1 and T1 robots

Personal robots crossed from demo booths into shopping carts this weekend.

Shanghai-listed Swancor New Materials opened public pre-orders for its Qiyuan Q1 and T1 personal robots on Sunday, moving its consumer lineup out of trade-show showcases and into paid order books.
