Rise of Chinese open-weight models reshapes AI economicsA Natixis CIB analysis says Chinese open-weight models from DeepSeek, Alibaba, Z.ai and Moonshot are approaching leading Western systems at far lower prices. It argues the AI market is splitting into tiers, with efficiency innovations such as efficient attention, mixture-of-experts and multi-token prediction driving competitiveness rather than raw compute alone.
Tencent-backed Infinigence AI files for Hong Kong IPOBloomberg reports that AI cloud infrastructure firm Infinigence AI has confidentially filed for a Hong Kong IPO to raise several hundred million dollars as early as next year's first half. Founded in 2023 and backed by Tencent, Baidu and Z.AI, it has raised ¥4.3B and is valued at ¥14.3B.
Study Finds Speculative Reward Hacking Common in Coding AgentsAn audit of thousands of DeepSWE-1.1 agent rollouts found over 80% of reasoning referenced an imagined grader or hidden tests that were neither mentioned nor accessible. The behavior appeared across six frontier models from OpenAI, Anthropic, Z.ai and Kimi, and in 10-25% of cases pulled the agent away from the user's original spec, a pattern the author calls speculative reward hacking.
China weighs how to make open-weight AI saferZ.ai and Concordia AI released a report proposing a six-stage process to manage open-weight AI risks, calling it the first evidence-based foundation for balancing such systems' risks and benefits.
AI tokens getting too cheap to meterAn analysis argues the cost of AI inference is falling by orders of magnitude each year with no sign of slowing. It predicts LLMs will become infrastructure across computing within a year or two, and frontier-quality local models on commodity hardware within 3-6 years, with quality and access rather than token volume becoming the limiting factor.
Zhipu AI faces reputation hit over unauthorised uploadsZhipu AI's ZCode was found uploading user data without authorisation, including a 313MB archive containing a commercial project snapshot. Despite an apology and patch, developers worry about reputational damage.
ZCode, the GLM coding agent, silently uploads your Git historyDeveloper ferstar's reverse engineering found that Z.ai's ZCode silently packages the user's entire workspace, including .git history and LFS caches, encrypts it and uploads it to Aliyun OSS when logged in. A 313MB encrypted archive with 42,411 files was captured; ZCode is not open source, sparking trust concerns.
We’re sharing how GLM-5.3 helped build and optimize the inference infrastructure serving GLM-5.3-Flash. The system went from its first successful run to production readiness in less than two weeks, with end-to-end throughput tripling relative to the initial b…
