## AI 摘要

作者抢先体验了微信AI助手“小微”。小微基于腾讯自研中文大模型WeLM，部分响应由DeepSeek处理。用户手动激活后，可设置日程、发消息、打电话、生成歌单、启动小程序，并能唤醒美团外卖和京东购物，但转账、红包等最终支付需手动确认。隐私方面：聊天信息仅当前会话读取，不保存、不用于训练，上下文记忆可手动关闭。微信拥有超10亿用户，而腾讯在大模型领域落后于字节和阿里，因此微信成为其最重要的AI落地窗口。支付宝也已在测试具备车辆预约和外卖配送能力的AI智能体。

We got early access to WeChat's new AI assistant "Xiaowei" and ran an initial test. Xiaowei says it's built by the WeChat team， runs on their in-house Chinese LLM WeLM， with DeepSeek handling some responses.
Users activate it manually. From there， Xiaowei can set calendar events， send messages， make calls， generate playlists， and spin up mini-programs - WeChat's lightweight in-app tools. It can wake up Meituan for food delivery or http://JD.com for shopping， but the final payment - including transfers and red packets - requires the user to tap through manually.
Privacy： chat messages are read for the current session only - not saved， not used for training. Context memory can be disabled manually.
The stakes are high. Tencent's top LLM development trails ByteDance and Alibaba， making WeChat - 1B+ users - its most critical AI launch surface. Alipay is already testing AI agents with vehicle booking and food delivery.
