The guys who keep shouting about AI phones taking off every day can finally see some runway this time. Just recently, many media released violent news,WeChat is cooperating with Huawei, Honor, Xiaomi and other mobile phone manufacturers to launch A2A (Agent-to-Agent) assistant capabilities, you can initiate WeChat audio and video calls through the mobile phone voice assistant, or send messages to friends.
Translated into adult language: From now on, if you say to the mobile assistant "Send Lao Wang a WeChat message", the mobile assistant no longer needs to pretend not to understand. It can hand over the request to WeChat, and WeChat will execute it on its own, and then return the results.

At first glance, this thing doesn’t seem so explosive. After all, it’s 2026. A mobile assistant can help you send WeChat messages. It doesn’t seem like it should be news, but more like a basic skill that it should have learned a long time ago.
But here's the problem.
In the past few years, AI mobile phone conferences have become more and more lively, featuring global intelligence, active services, and cross-App services. At the conference, there are all kinds of ticket booking, car hailing, and message sending in one sentence. The demonstration video is as smooth as a charade.
But when it comes to national-level applications like WeChat, many AI functions suddenly become polite and even cautious.It doesn't move around, it doesn't cross the line, and it doesn't do much. It just stands outside the door.
Until today, WeChat has opened the door just a crack. Even if it is just "a crack", Lei Technology believes that WeChat's move will have a profound impact on the AI technology industry.
Works, but doesn’t have many features
Let’s first talk about what WeChat and manufacturers have done.
In the past, when mobile phone manufacturers were agents, they liked to take the approach of "I will take over the phone." It requires looking at the interface, finding buttons, simulating clicks, and then waiting for the page to jump.
In theory, it is very powerful and can be used by any app, but the problem is also obvious.
You, a mobile assistant, suddenly have to help users click on WeChat, click on Alipay, click on Meituan, and click on banking apps. What will the application manufacturers think?
They will definitely be nervous.
Because there are not just buttons, but also user data, payment risks, risk control rules, and the core entrance control rights. Just because you can do it technically doesn’t mean that others are willing to let you do it commercially.

For comparison, WeChat supports this timeA2A standard protocol, originally officially proposed by Google and open sourced in April 2025, it allows different agents to directly establish communication, assign tasks and work together, allowing the mobile assistant to send requirements to WeChat, and WeChat will judge, execute and return by itself.
Precisely because the decision-making power is in the hands of WeChat, it dares to allow external AI assistants to call several types of low-risk, high-frequency WeChat capabilities.
What can be done specifically... In short, I took a Honor Magic8 RS here for everyone to test.
The method of use is quite simple, just call out YOYO assistant and then give it commands.
When you activate WeChat for the first time, WeChat will remind you to obtain smart assistant permissions. This estimate is consistent with the WeChat Agent itself that will be launched later.

The next operation is very simple. You can use "Open WeChat Scan" to call out the scan interface.

Use the command "Send XX WeChat and say OOOO" to send a text message, but the operation speed after the jump is not very fast, and you still need to manually confirm whether to send it or not.

You can make a voice/video call by using the command "Make a WeChat voice/video call to XX". You also need to manually confirm whether to dial or not, but the operation speed will be faster than sending a text message.

WeChat collection/payment codes can also be called, but I won’t show this.
In addition to these relatively basic functions, there are currently quite a few functions that WeChat does not support, especially operations that slightly involve personal privacy/property security, such as sending photos/videos to friends, sending red envelopes/transfers to friends/group chats, and even using WeChat to open specific pages of official accounts is not supported.

For comparison, I tested Super Little Love by the way.
What is certain is that without access to the WeChat A2A assistant, the mobile assistants of various manufacturers can also call up the WeChat scan and receive/pay codes, which is still very convenient for payment.
However, the message really cannot be sent, and the furthest it can go is the step of "opening WeChat".

According to industry insiders, currently all Honor Magic8 series, 500 series and X70 series support WeChat A2A assistant capabilities, and other manufacturers are also following suit.
I have to say that this is of course a good thing for mobile phone manufacturers. In the past, AI assistants would get stuck when encountering WeChat, but now they can at least do some high-frequency tasks.
This is not a loss for WeChat either. It does not fully release the core authority, and can avoid being said to be an island in the AI era.
More importantly, this is likely to pave the way for the WeChat Agent later.
Start with low-risk actions such as sending messages and making voice calls, and run through the vendor collaboration, permission boundaries, user confirmation, and risk control processes. When users get used to it and manufacturers get used to it, they will slowly open up mini programs, public accounts, video accounts, and corporate WeChat capabilities, and then there will be room to continue telling stories.
Everyone wants AI to loop on its own
Since the emergence of Agents, people have been thinking about ways to break the silo problem.
As early as November 2024, Anthropic proposed the MCP (Model Context Protocol) protocol, which is a unified and standardized communication protocol. The purpose is to allow large models to safely and standardly request three things from external applications: prompt words, resources and executable tools.
The existence of the MCP protocol turns the large model from a chat box into an intelligent assistant that can connect everything.
The problem is that under the architecture of the MCP protocol, the large model is the absolute subject, and external applications are just tools that are called. When all the user's perception, interaction, and intention understanding are completed in the mobile assistant or other large models, the application naturally degenerates into the underlying "service API".

For large manufacturers, this situation cannot be tolerated.
Because of this, it is difficult to see major manufacturers taking the initiative to adapt to the MCP protocol. Alibaba and Byte, everyone is actually rushing in the direction of Agent, but their attitude is highly consistent: it can be opened, but it will be opened in my yard first.
Among them, Ali is a typical example.
Qianwen is now connected to Alibaba's ecological businesses such as Taobao, Alipay, Taobao Flash Sales, Fliggy, and AutoNavi. It can shop, order takeaways, book flights, and plan routes. It can be said to be reconnecting the Alibaba family.
This path is smooth, because these capabilities are already within the Alibaba system. Permissions, payment, contract performance, and customer service can all be linked together, eliminating the need to negotiate with others every day.

But here's the problem.
It is very strong, but it is strong within Alibaba’s own ecosystem. If you ask Qianwen to make in-depth calls to WeChat, Douyin, and Meituan, the difficulty will rise immediately. It’s not that the model doesn’t know it, but that others may not be willing to give it.
Byte is similar. Doubao is now connected with Douyin e-commerce. Users can mention shopping needs in Doubao, and then complete recommendations, product selection, ordering, and payment; Butanzi is responsible for the Agent platform, which can query and call a series of Byte-based applications.They want more tasks to be done on the byte table.
So you will find that everyone talks about Agent, but in fact it is a closed loop within the ecosystem.
Alibaba has connected the Alibaba system, and Byte has connected the Douyin system. Mobile phone manufacturers seem to be standing at the system level, closest to users, but farthest from real services.
You know, it's hard to stretch.
Say it at the end
You may be wondering why WeChat’s opening of A2A has received widespread attention?
Because it provides the industry with a more realistic answer: major manufacturers do not have to attack and exclude each other. They can also have one agent hand over tasks to another agent just like companies issue work orders.
The mobile assistant is responsible for understanding you, the WeChat Agent is responsible for processing things in WeChat, the mini program is responsible for completing specific services, and the user is responsible for final confirmation.No one crosses the line indiscriminately, but the tasks can be run through, and the traffic of large factories is not damaged.
To me, this is much more realistic than "super AI taking over everything".

Of course, don’t think of this opening as too romantic.
WeChat is just a small opening, and A2A is not a master key. It solves the problem of "can we collaborate", not the problem of "it will be easy to use after collaboration".
Whether the experience is good or not depends on whether the model is smart enough, whether the permission design is clear enough, whether the payment confirmation is safe enough, and whether there is a cover for mistakes.
At least for now, many netizens are still not satisfied with the performance of WeChat’s own agents.

But in any case, the industry signal given by WeChat when it opens its doors this time is already very obvious.
As for whether there is a broad road behind this door or the next round of entrance war, it depends on how each manufacturer plans to fight next.
