WeChat is introducing new rules that require users to label any AI-generated content they share, including videos and public posts. The platform may also add its own visible or invisible labels to content to increase transparency.

When posting on a public WeChat account, users must indicate if any content—whether video, image, or text—was generated by AI and choose the appropriate category, including official/media, news, entertainment, personal opinion/reference only. | Image: Screenshot via WeChat

These changes follow China's government regulation on mandatory labeling of AI-generated content, which takes effect on September 1, 2025. Users who ignore the rules, such as by removing required labels or sharing misleading content, will face penalties, according to WeChat.

Alibaba has developed a new AI chip, which is currently in testing, designed for a broad range of inference tasks, such as powering the responses from a smartphone voice assistant. The chip is manufactured by a Chinese company and is more versatile than Alibaba's older chips. It is designed for inference, not for training AI models—an area where China's biggest weakness lies compared to the US.

As reported by the Wall Street Journal, Alibaba's new chip is compatible with the Nvidia software platform, meaning engineers can repurpose programs written for Nvidia hardware. The chip helps to fill the void created after Nvidia ran into regulatory barriers restricting sales of its products in China. Alibaba was long one of Nvidia's biggest customers before these restrictions were put in place.

Anthropic is rolling out new data privacy controls for Claude. Users on the Free, Pro, and Max plans must now actively opt out if they don't want their conversations used to train AI models.

The new setting only applies to new or ongoing chats and can be changed at any time. If you allow data use, Anthropic will keep your chat data for up to five years to help improve its models and security systems. If you opt out, your conversations are stored for just 30 days. These changes don't affect Claude for Work, Education, Government, or API access through partners like Amazon Bedrock.

Users have until September 28, 2025, to make their choice. After that, you'll have to select a data sharing preference to keep using Claude.
