WeChat Tests AI-to-AI Chat as Meta Opens Muse Agent Trials

The Chinese technology publication ifanr reported that WeChat is testing “Xiaowei AI social.” The feature would let a user ask Xiaowei to contact another person’s Xiaowei and return an answer, so neither participant needs to type a direct message. The report said the feature is an internal test.

ifanr said the test fits a wider agent-to-agent (A2A) trend. Enterprise WeChat has announced upgrades that let agents such as Workbuddy and DeepSeek Harness read documents, spreadsheets and calendars through its interface. Google’s A2A protocol, now under the Linux Foundation, counts more than 150 supporting organizations, according to ifanr. Those moves suggest software is increasingly being designed to be usable by machines as well as people.

ifanr also cited several security concerns. An agent-only forum called Moltbook attracted more than 1.5 million AI accounts within a week this year; an analysis by Originality.ai found factually harmful errors on the forum at roughly three times the rate of comparable Reddit discussions, and agents often repeated those errors with confidence. A Harvard Medical School commentary cited by ifanr described a hypothetical emergency department in which one agent misreads an X-ray and later agents act on that wrong diagnosis.

The same article noted a Reuters report about a GitHub attack in which two accounts disputing a warning were later shown to be decoy accounts created by Anthropic Mythos 5 agents during a security test. To address such risks, engineers submitted a draft to the Internet Engineering Task Force in March proposing agent authentication and authorization based on OAuth 2.0 and WIMSE.

Separately, Android Authority reported, citing Testing Catalog, that Meta’s Muse assistant has entered a closed alpha stage, although the report later calls it a closed beta. Meta plans to use a waitlist and invite codes, and an App Store listing for “Muse from Meta” shows the assistant performing proactive actions, requiring approval before messages or spending, tracking ticket and reservation prices, and integrating with Gmail, Google Calendar, health apps such as Peloton and HealthEx, payment cards and bank accounts. The listing says Muse can track expenses and recommend canceling unused subscriptions, according to Android Authority. The test follows Meta’s release of Muse Spark and of a local AI model last month.

Android Authority noted that Meta’s privacy record is not reassuring and questioned whether users will widely adopt the agent after launch.
