Chinese AI Startups MiniMax, Zhipu AI Set Hong Kong IPOs
Chinese AI startups are flocking to the Hong Kong Stock Exchange for IPOs. MiniMax and Zhipu AI plan listings in early January 2026, aiming to raise roughly $540 million and $560 million respectively. Meanwhile, Moonshot AI, known for its Kimi chatbot, secured a $500 million Series C round led by IDG Capital, valuing the company at $4.3 billion, and has no immediate IPO plans. The article also notes that Singapore-based AI agent startup Manus was acquired by Meta for about $2 billion. These moves come amid US chip export restrictions and intense competition in the open-source AI model space, positioning Hong Kong as a key fundraising hub for China's tech sector.
Chinese AI IPOs and funding signal significant capital flows into AI infrastructure, indirectly impacting AdTech's reliance on AI models.

Anthropic's Claude Integrates with Google Docs, Sheets, Slides
Anthropic has integrated its Claude AI assistant directly into Google Docs, Sheets, and Slides, appearing as a sidebar alongside Google's Gemini. This public beta is available for paying Claude customers via Google Workspace Marketplace add-ons. Claude can edit text, create formulas, pivot tables, and charts, and check slide layouts. Users can control its autonomy, with a default approval mode and an 'Accept all edits' mode for batch tasks. Team and enterprise admins must enable new Google Workspace connectors. A guest column by Ting Wasner-Lian analyzes Google's strategic decision to host a competitor, arguing that Google's subscription model profits regardless, and locking out Claude could drive users to Microsoft 365. The article compares this to Alibaba's DingTalk, open to external AI models, and contrasts it with SAP's data access fees, citing Celonis's lawsuit. Advice for European companies on securing AI agent access in contracts is also provided.
Anthropic Warns China's GLM-5.3 Builds Exploits Like Mythos
Anthropic's Frontier Red Team published an analysis warning that Z.ai's open-weight model GLM-5.3 can autonomously build full cyber exploits, comparable to its restricted Claude Mythos Preview but without meaningful safeguards. In tests, GLM-5.3 produced 50 successful exploits for known Chrome V8 vulnerabilities out of 410 attempts (close to Mythos's 56), and discovered multiple unknown vulnerabilities in a common browser within a day, chaining them into a working exploit. Anthropic notes that safeguards can be bypassed in 64-100% of cases with simple tricks, and removing them costs only about $4,400. The US NIST's CAISI assessed GLM-5.3 as the most cyber-capable open-weight model to date, though it lags US frontier models by about four months. Z.ai, listed in Hong Kong since January, has seen its market value drop to about $40 billion from $120 billion in June. Critics question Anthropic's commercial motives and highlight defender benefits.
GLM-5.3 Sparse Attention Impact on DRAM Memory TAM
This article analyzes the impact of sparse attention mechanisms, specifically DeepSeek Sparse Attention (DSA) used in Z.ai's GLM-5.3 model, on the total addressable market (TAM) for DRAM memory, including HBM and NAND. It explains that while sparse attention reduces KV cache memory and bandwidth during the attention operation, it does not reduce overall memory capacity requirements because the top-k selection still requires full context in HBM. The article discusses system optimizations like HiSparse, which offloads KV cache to host DRAM to overcome capacity bottlenecks. It also provides detailed performance and cost comparisons for serving GLM-5.3 on different hardware (GB200, GB300, MI355X) using inference engines like Dynamo-SGLang, Dynamo-TRT-LLM, and ATOM, highlighting cost-efficiency and interactivity trade-offs. The analysis includes a deep dive into GLM-5's architecture, including the lightning indexer, MLA configuration, and post-training pipeline.
