Tencent slots an AI agent into 14 million companies' contact lists
China's biggest workplace chat app now lists an AI agent as a colleague. Tencent shipped a deep two-way integration between WeCom and its WorkBuddy office agent, and it went out to the version of WeChat that businesses actually run on.
WorkBuddy now sits in the WeCom contact list as a conversational bot — not a sidebar plugin. In WeCom 5.0.12, the agent appears next to human colleagues and can be messaged like one; WorkBuddy 5.8.0 in turn logs in with a WeCom account and inherits permissions across messages, documents, meetings and cloud drive, which Tencent counts as ten capability grants. The point of the release is the account layer: administrators assign bot seats, set per-role permissions, meter usage and buy AI compute centrally, so the agent is a managed corporate identity rather than a thousand employees quietly pasting company documents into a personal chatbot. Tencent says the integration is open to verified enterprises with free-trial seats, and that L'Oréal, McDonald's and BYD are exploring deployments.
That second half is the honest story, and Tencent's framing leans on it. The reach numbers — more than 14 million enterprises and organizations on WeCom, 750 million WeChat users served daily — are company figures repeated by every outlet, and the named customers are described as exploring, not deployed. There is also a structural caveat worth flagging: WorkBuddy lives inside Tencent Cloud while WeCom sits in the WeChat business group, two separate lines, and at least one Chinese analyst outlet argues the link is capability docking over MCP rather than native integration — context fusion stays incomplete, with data, permissions and organizational memory not fully interconnected at the base layer. Read as an announcement, this is Tencent consolidating its biggest distribution surface into an AI platform. Read as a product, it is the first version of one.
STEPX launched the STEPX Neo, a phone built around an agent OS rather than an app grid, priced as a full-stack bundle at 3,999 yuan. StepFun's terminal brand held its "Ready Builder One" launch in Shanghai on October 13: the handset runs Step AOS 1.0, an agent-native operating system that puts long-term memory, task scheduling and safety controls below the app layer, paired with a personal agent called Amoo and a dual-domain memory split between the user's personal context and the agent's accumulated know-how. Simple commands run on-device, including offline; harder multi-app tasks get planned in the cloud and executed locally. Step Studio, a natural-language IDE that generates apps, games and skills — and speaks MCP and A2A to outside agents — is the developer hook.
The pricing is the part to watch. StepFun sells models, OS, tooling and hardware as one SKU — 3,999 yuan, roughly $560 — and throws in twelve months of a token plan at 100 billion tokens a month, a bet that agentic phones are judged on what they can do rather than on specs and app catalogs. Around 100 partners, Alipay and Tencent among them, have signed on. Pre-orders opened October 13; open sale is October 16.
MemSilicon taped out MountTai 2026, a 1 Gb RRAM chip it calls the first high-density, high-capacity part on a 1T4R cell. The Beijing-and-Shanghai startup's design shares one select transistor across four resistive memory cells on a 28nm CMOS platform, reaching 30 Mb/mm² with sub-20-nanosecond access and on-chip error correction — the density trick being that RRAM cells are cheap to stack but each normally needs its own transistor to address. If the approach holds, it points at embedded non-volatile memory that is fast enough to sit close to logic without the cost of DRAM. Treat the framing carefully: this is a tape-out, not silicon results, verification is still running, and "international first" is the company's claim, not a third-party measurement. Five years of claiming 1TnR as a research direction and promising productization is the milestone; the mask is not the chip.
