Kuaishou is spinning out its Kling AI video-generation model into a separately financed company, attracting investment from Tencent, Alibaba Cloud, Baidu, and other institutions at an implied valuation of $18 billion. Kling has surpassed 100 million global users and nearly 50,000 enterprise customers, but continues to generate substantial losses because of compute costs.
Entropic Scree is an open-source, model-agnostic diagnostic that uses Normalized Mutual Information to estimate intrinsic rank in complex tabular datasets. It aims to reduce the overestimation and structural failures associated with PCA, Kernel PCA, and Euclidean nearest-neighbor estimators.
Moonshot and ZAI are reportedly approaching the performance of models from OpenAI and Anthropic. The models can reportedly build passable websites at a cost 75% lower than Claude, highlighting potential advantages in cost-sensitive coding workflows.

Ant Group’s quarterly profit barely grew after the company increased spending on artificial intelligence. The investments target healthcare, large language models, and payment services, while expansion costs also pressured results.
New releases from Chinese competitors are narrowing the gap with Silicon Valley’s AI products, including ChatGPT and Gemini. Lower pricing is helping these services gain market share, alongside offerings such as DeepSeek and Kimi agents.
Interviews with three doctors reveal that medical AI annotation and evaluation work is demanding, increasingly commoditized, and vulnerable to cost-cutting. While models show measurable improvements, practitioners remain concerned that increasingly capable systems could eventually replace parts of their own work.

Falling model prices are paradoxically driving up total AI spending. Gartner predicts that AI inference costs per workflow could rise more than fivefold by 2028, making ROI management increasingly important.
KPMG UK Chief Economist Yael Selfin says rising chip and AI model costs are filtering through the UK economy. However, higher household energy costs remain a much larger inflation concern for the Bank of England.
The Google Pixel 11 costs $100 more than last year's model while introducing relatively few major changes. Despite the higher price and limited evolution, it remains one of the strongest smartphones on the market.
