Shenzhen clears delivery robots to work the night shift

Two stories frame the weekend: China's parcel robots are going nocturnal, and Apple is days away from putting Siri at the center of the home. Shenzhen has become the first city in China to let driverless delivery vehicles operate at night — and the experiment is scaling faster than the robots can be built. The city granted nighttime road access in March 2026, after which after-dark routes grew from 2 to 437, with more than 170 driverless vans now running parcel runs once the streets empty.

Microsoft builds its decision model on Qwen, not OpenAI

Sunday's haul mixed one real model launch with a milestone for China's driverless delivery fleets — and a robotics round that's really about drug-making capacity. Microsoft launched Microsoft-Decision-1, a fast decision-scoring model built by post-training Alibaba's Qwen3.5-9B. Unlike an LLM that generates text, a decision model returns a calibrated probability — the kind of call an agent makes when it routes a ticket, flags an incident, or approves a refund.

DeepSeek's cheap long-context trick leaves periodic blind spots

Ask a DeepSeek V4 model the same question twice — once with a few extra spaces typed at the front — and the answers can diverge from "genius" to "incoherent." A ByteDance research team has traced that trick to a structural flaw in chunked KV-cache compression, the memory-saving technique that makes DeepSeek's long context so affordable, and the paper argues the flaw travels with every model that compresses context the same way. The bug, in plain terms Long contexts are expensive because…

Tesla drops 'Full Self-Driving' name in Europe after regulator push

Two stories today sit on the same question — who gets to name what AI actually does. Tesla blinked first in Europe; in China, a founder with a very public sabotage history is betting $30 million that investors will pick technical brilliance over a clean record. Tesla is renaming "Full Self-Driving (Supervised)" to "Assisted Driving" across Europe after German regulators called the brand name "somewhat misleading." The German Federal Ministry of Transport said Tuesday the system "is not a…

Deep Dive — The four-token blind spot inside DeepSeek V4

ByteDance's Seed research team says it has found the cause of one of the stranger recurring complaints about DeepSeek's models: the same question, asked with nothing changed except a few junk characters bolted onto the front, can flip the model from right to wrong. Their paper, posted to arXiv on September 28, traces the wobble to a memory-saving trick used during long-context inference, and reports that DeepSeek-V4-Flash-Base's retrieval accuracy swings by as much as 40.2 percentage points…

Lei Jun's fund and Huawei's Hubble back DiffuSpace's record round

Chinese money went after a non-autoregressive architecture this morning, while one of the world's most-watched investors delivered his sharpest warning yet that the AI trade is closer to the exit than the entrance. Shenzhen's DiffuSpace has closed two back-to-back rounds totaling several hundred million yuan — according to reports, the largest funding ever raised by a diffusion language model startup, and the company's first disclosure since it was founded this May.

Mistral unveils Le Chonk: a 1T-parameter open-weights model

The biggest open-weight release outside China lands in public preview today, and the country that spent the week promising its own frontier model just put a price on the ambition. Mistral has opened a public preview of Mistral Large 4 — codenamed "le Chonk" — a 1 trillion-parameter mixture-of-experts model with 49 billion active parameters, natively multimodal, which the company calls its largest and most capable model to date.

DeepSeek nears $12B round with Tencent and CATL ahead of IPO

Three stories shape the last 24 hours: a record-scale fundraise at China's most famous model lab, a first-of-its-kind hearing at New York City Hall, and Cohere rebuilding its enterprise agent platform around other people's models. DeepSeek is close to raising at least $12 billion — 80 billion yuan — in a single round that could reach roughly $14.9 billion, after investor demand outstripped the company's own target, with Tencent and battery maker CATL as the biggest contributors, people…
