Zhipu AI
The open-weight GLM family of models, spun out of Tsinghua University; now listed as Z.ai.
Zhipu AI is a Chinese lab that grew out of Tsinghua University's Knowledge Engineering Group and builds the GLM family of models. It was an early mover in open Chinese models, releasing the bilingual ChatGLM-6B in 2023 — small enough to run on a single consumer graphics card — well before the larger open releases from Alibaba and DeepSeek that followed. Now trading publicly as Z.ai after a Hong Kong listing in early 2026, it releases frontier-scale models under permissive licences. Its 2026 GLM-5, reported to have been trained entirely on Huawei Ascend chips rather than Nvidia hardware, drew particular attention as a marker of China's effort to build an AI compute stack independent of US export controls; the company has been on the US Commerce Department's Entity List since January 2025.

Z.ai says GLM-5.3 built much of its own inference stack
The company said an agent built on its own model tripled inference throughput on a 100,000-chip domestic cluster within two weeks, while insisting humans kept control of objectives and risk.

Study detects reward hacking from models' internal representations
Cheap difference-of-means probes on frontier open-weight models matched expensive LLM-judge monitors at catching reward hacking, at a fraction of the compute cost.

Zhipu raises $5bn in two months
A Hong Kong share placement and zero-coupon convertible bonds followed a $4bn raise in July, taking money raised since January's IPO to roughly $9.6bn.

Anthropic details how states and criminals misused Claude
Anthropic's September threat report said Claude had been used to write missile-guidance software for a Yemen weapons cell and to support biological-weapons research, alongside autonomous cyberattacks, state surveillance and the Chinese distillation campaigns.

US agencies accuse six Chinese labs of distilling US AI models
A joint NSA/CISA/FBI advisory named DeepSeek, Moonshot, Alibaba, MiniMax, StepFun and Z.AI as running systematic distillation campaigns against Claude, GPT, Gemini and Grok since late 2024; China's Commerce Ministry rejected it and threatened countermeasures.

Zhipu reveals GLM-5.3-Flash after testing it anonymously online for a week
Priced at roughly a tenth of GLM-5.2 and released under an MIT licence, it is the first natively multimodal model in the GLM-5 series.

Zhipu releases GLM-5.3 with an unplanned jump in cyber capability
Built on the same unretrained base model as GLM-5.2, it scored 84.5% on the CyberGym vulnerability-discovery benchmark and had its weights withheld for roughly two weeks.

UK AISI and US CAISI jointly assess Moonshot AI's Kimi K3 for cyber capability
Kimi K3 failed to produce a working exploit on any of 41 code-execution tasks, versus 20 of 41 for the leading closed US models tested with safeguards disabled.

UK AISI reports narrowing cyber-capability gap between open-weight and closed frontier models
On a 70-task cyber suite, GLM-5.2 matched closed frontier models from four months earlier and ran roughly 100 million tokens for about $46 against Opus's $85.

US CAISI publishes assessment of Z.ai's GLM-5.2
The US assessment found GLM-5.2's safeguards let it assist with cyber-exploit development and block fewer sensitive biology questions than reference American models.

WSJ reports China has 'matched' Anthropic in cybersecurity; Zvi and others dispute the framing
Critics said the report conflated finding vulnerabilities when pointed at them, which GLM-5.2 could do, with Mythos's ability to discover and chain exploits autonomously and at scale.

GLM-5.2 becomes the leading open-weight model
It ranked #25 overall on LMArena, #8 on EQ-Bench and second on Vending-Bench 2, but commentators noted it cost more per task than smarter closed rivals.
