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

China's gray market sells Claude tokens at a tenth of the list price

Anthropic runs what are probably the strictest access controls of any major AI provider when it comes to China — phone and billing checks, bans on majority-Chinese-owned firms, and even live-selfie ID verification for some users. Yet Chinese developers can still buy Claude tokens for roughly 10 percent of the official price. A detailed analysis by Zilan Qian, a researcher at the Oxford China Policy Lab and published by ChinaTalk, maps the thriving gray market of "transfer stations" that routes a

AI 101 — What is a learned kernel?

A learned kernel is the low-level math software that runs on a GPU and was designed — or tuned by trial and error — by an AI program, rather than hand-written by a human engineer. When a large language model does its math, it doesn't just "think" in a clean way: every layer boils down to enormous matrix multiplications that must be executed millions of times per second. On Nvidia GPUs those operations are performed by special routines called kernels. Today almost all of them come from hand-tune

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. Alibaba plans a ~US$10 billion share placeme

Liquid AI's 230M model beats models four times its size at data extraction

Small models are quietly winning the jobs nobody brags about. Liquid AI says its tiniest LFM2.5 release yet — a 230-million-parameter model — outperforms rivals four times its size on data-extraction work, and it is small enough to run almost anywhere. Liquid AI's new LFM2.5-230M tops models roughly four times its size on extraction benchmarks while running on hardware as modest as a phone, according to the company's announcement. The claim matters because extraction — pulling structured fields

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

Personal robots crossed from demo booths into shopping carts this weekend. Swancor New Materials — the listed company humanoid-maker Agibot took control of last year — has thrown open public pre-orders for its Qiyuan Q1 and T1 consumer robots, with the first units slated to ship next month. 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.

Early tests of mystery model Ox Alpha can't agree if it's frontier

The mystery model that appeared on OpenRouter this week with no name attached is still free, still anonymous, and now the center of a very public argument about whether it's any good. Early benchmark results are pointing in opposite directions — and the fight over Ox Alpha's report card is becoming the story. Early tests of mystery model Ox Alpha can't agree if it's frontier. The anonymous model surfaced on OpenRouter earlier this week offering a 1M-token multimodal context window, zero data re

A homelabber is strapping 36 Nvidia DGX Sparks together for 4.6TB of local AI memory

The most interesting AI data center on the internet right now sits in somebody's server room. A redditor known as Kurcide — who built what he believes was the first 16-node DGX Spark cluster earlier this year — has posted an upgrade: 20 more of Nvidia's palm-sized AI boxes are going into the rack, taking "the All Spark" cluster to 36 machines and roughly 4.6TB of unified memory. That is enough to hold some of the largest open-weight models in existence entirely on one private machine, no cloud a

One attention head carries a chess transformer's queen sacrifice

Mechanistic interpretability rarely gets a result this clean: switch off a single head, and a chess AI loses Morphy's most famous move. Silencing one of a chess transformer's 128 attention heads makes the model stop finding the Opera Game queen sacrifice, according to a project post on r/MachineLearning this weekend. The demonstration comes from chessformer_lens, a new open-source interpretability toolkit for square-tokenized chess models. Its author hooks into Maia-3 — a 23-million-parameter m

One week with Qwen 3.8 27B — the local LLM community's verdict

Seven days after Alibaba dropped a frontier-grade coder onto consumer GPUs, the community has had time to do what it does best: benchmark it, compress it, wire it into every inference stack available, and argue about what it means. One week after Qwen 3.8 27B landed as a free download, the consolidated verdict from r/LocalLLaMA and r/LocalLLM lands where few expected a 27-billion-parameter model to arrive: doing real, paid production work on hardware people already own.

Figmimic turns any webpage into editable Figma layers

The most useful design tool of the weekend is 15 lines of JavaScript. Figmimic, a bookmarklet from B12 engineer Andrew Musselman, copies any webpage you're looking at into Figma as fully editable frames — real nesting, real layers, not a flat screenshot — via a single click from the bookmarks bar. It hit the Hacker News front page on Friday and has been making the rounds among designers since. What makes it more than a novelty is reach.

Harvey's Tenet nearly doubles held-out legal wins over its Kimi K3 base

Legal AI's boldest open-weight bet just got its first real receipts — and Washington is already citing them as policy evidence. Plus: US model prices keep sliding. Harvey published its first benchmark results for Tenet, and the post-trained Kimi K3 model completes almost twice as many held-out legal tasks as the open-weight base it started from. In a research update posted Thursday, the $11 billion legal-AI company reports a 9-percentage-point jump in all-pass rate on held-out tasks from Vals'
