WeChat Launches Native AI Assistant "Xiaowei": Self-Developed WeLM + DeepSeek Dual Model, Social Platforms Become the New AI Battlefield

📖 Glossary

AI Box (also known as Agent Computer / Agent PC), is a dedicated local hardware device that runs AI Agents. Pre-installed with an AI agent management system, plug-and-play, running 24/7. Users can remotely command AI to work via Discord, Slack, Telegram, WhatsApp, and more.

Abstract: WeChat officially began grayscale testing of its native AI assistant "Xiaowei" — a green eye icon in the top-left corner of the home screen. Core capabilities include: self-developed WeLM + DeepSeek dual models, one-command control over all WeChat functions, triggering mini programs, and one-command generation of mini program prototypes. 1.3 billion MAU + AI assistant — social platforms have officially become the super-distribution channel for LLMs.

Open WeChat today. There's a new green eye icon in the top-left corner of the home screen.

Tap it — it's an AI assistant. Called "Xiaowei."

This isn't someone else's AI plugged into a WeChat entry point. This is WeChat's own native AI assistant.

What Xiaowei Can Do

Based on grayscale testing feedback, Xiaowei has five core capabilities:

1. One-Command WeChat Control

Send messages, post in Moments, change settings, create groups, add people. All by voice or text.

"Xiaowei, send a message to Zhang San saying I invite him to dinner tonight."

Xiaowei opens the chat, composes the message, just waiting for you to hit send.

"Xiaowei, post a Moment: beautiful weather today, attach this photo."

Photo selection, caption, visibility settings — Xiaowei does it all in one step.

2. Triggering Mini Programs to Complete Services

This is both the most practical and the boldest capability.

"Xiaowei, book a hospital appointment for 2 PM tomorrow."

Xiaowei understands your request, triggers the hospital mini program inside WeChat, auto-fills your information.

"Xiaowei, order me an American coffee."

Triggers the Luckin mini program, selects, places the order.

You're not using a mini program. You're using WeChat's Xiaowei, and Xiaowei is using the mini program for you.

3. One-Command Mini Program Prototype Generation

This is the most impressive capability.

"Xiaowei, create a simple itinerary app for me tomorrow."

Xiaowei uses natural language understanding to grasp your needs and generates a mini program prototype. The functionality is simple for now, but the direction is clear — in the future, you may not need to open a mini program at all. Xiaowei will "sculpt" one for you on the fly.

4. Content Search + Image Generation

WeChat search combined with AI generation, all completed within the app.

"Xiaowei, find last month's article about AI Agents."

Retrieves historical content, precise targeting. Can also summarize for you.

"Xiaowei, generate an image of a cat sitting at a computer."

AI image generation, no need to switch to a third-party tool.

5. Self-Developed WeLM + DeepSeek Dual Model

Xiaowei runs on two models working in tandem. WeLM is WeChat's self-developed Chinese LLM for daily conversation and Chinese comprehension. When complex reasoning or programming tasks arise, it automatically coordinates with DeepSeek V4.

WeLM handles daily tasks. DeepSeek handles the hard stuff. Clear division of labor.

Why This Is a Milestone for WeChat

Over the past year, WeChat's AI moves have been slow. Yuanbao was integrated as a WeChat entry point, but that was Tencent Yuanbao — not WeChat's own.

Xiaowei is WeChat's native AI assistant. The green eye in the top-left corner sits alongside Chats, Discover, Contacts. Not a third-party plugin — a core WeChat feature.

This means one thing: WeChat has decided to build its own AI entry point.

A social platform with 1.3 billion MAU now has an AI entry in the top-left corner. This will have a massive impact on the traffic landscape for all AI products.

Xiaowei vs the AI on Kaihe AIBOX

There's one core difference: Xiaowei runs on WeChat's cloud.

Asking Xiaowei about weather, posting Moments, ordering coffee — these are public actions, fine for the cloud.

But if you ask Xiaowei to check your bank balance, read a contract, or process company files — that data has to pass through Tencent's servers.

It's not that you don't want to use AI. It's that you don't want your private data leaving your device.

This is where Kaihe AIBOX fits — your local AI Agent runs on your own hardware, data never leaves your network. At the same time, the local Agent can collaborate with Xiaowei via WeChat API — using the cloud for third-party services while keeping private data local.

AI Box (also known as Agent Computer or AI Box) is a dedicated local hardware device that runs AI Agents, pre-installed with an AI agent management system, plug-and-play, running 24/7. Kaihe AIBOX provides local Agent capabilities that you can control remotely via WeChat — the convenience of Xiaowei on the cloud, plus the security of local Agents. All in the same app.

What Xiaowei's Launch Means

For users: WeChat has transformed from a chat tool into an AI service platform. You don't need to learn new AI products — WeChat is your AI entry point.

For developers: If Xiaowei opens mini program Agent capabilities, developers within WeChat's ecosystem gain a new traffic entry point. You don't need to reach 1.3 billion users — being "recommended by Xiaowei" is enough.

For Kaihe AIBOX: The more WeChat builds AI entry points, the more local Agents are needed for data security complement. Cloud for convenience, local for privacy — complementary, not substitutive.
