Five days.

On June 16, the AI version of Alipay opened internal testing, called by Geek Park "Alipay's biggest redesign in twenty years." On June 20, WeChat's AI assistant "XiaoWei" launched gray-rollout testing; some users can already summon it directly in chat.

Two national-level super-apps, collectively covering over 1.6 billion monthly active users, showed their Agent cards within less than a week. This is no coincidence, nor an ordinary feature iteration -- it is a quiet war over "the next-generation internet gateway."

From "Clicking Icons" to "Saying a Sentence"

To understand the weight of this war, you need to look back at two great migrations of the internet gateway.

The first was the PC era, where gateways were browsers and search engines -- you opened Baidu, typed keywords, and hunted for answers among blue links. The second was the mobile era, where gateways were app icons and super-apps -- you opened WeChat, found the corresponding service in the nine-grid, and clicked through step by step to complete a transaction.

These two migrations shared one characteristic: people seeking services. You needed to remember paths, click, navigate through layers of menus.

What the Agent era does is reverse this logic entirely: services finding people.

You don't need to open the Didi app, enter a destination, choose a car type, confirm payment -- you just say to your Agent "book me a car to the airport tomorrow at 8 AM," and the Agent handles the rest. You don't need to open Meituan, search restaurants, compare prices, read reviews, make a reservation -- "find me a quiet restaurant near the office suitable for four people to talk business, tonight at 7, under 200 RMB per person," and the Agent gives you a result directly.

QuestMobile data is telling: in March 2026, WeChat mini-program MAU hit 973 million; Alipay 644 million; Douyin 273 million. Those 973 million and 644 million people are already accustomed to doing everything inside super-apps. But what if one day they no longer need to open apps, and can just talk to their phones to complete everything?

WeChat's Restraint vs. Alipay's Aggression

Interestingly, WeChat and Alipay chose two very different paths.

WeChat continued its consistent "don't disturb users" philosophy. "XiaoWei" doesn't use Tencent's own Hunyuan as its main model; instead it uses the self-developed WeLM, and in some scenarios directly calls DeepSeek. This choice is telling -- it means WeChat prioritizes "user experience stability and cost control" over "flexing technical muscle" when it comes to Agents.

More notable is the "one-sentence mini-program generation" capability. This isn't simple code generation -- it means WeChat is lowering the barrier to "service creation" to zero. In the future, a merchant won't need a dev team, won't need to submit for review, won't need to wait for launch; just describe what you want, and the Agent directly generates a working mini-program. What this means for the tens of millions of small and medium merchants in the WeChat ecosystem is hard to overstate.

Alipay is playing an entirely different game. After trying the AI Alipay beta, Geek Park used a precise label: "Agent-ready." Ant Group internally positions this version of Alipay as a "super gateway for Agent services." Its goal isn't just letting users complete transfers, bill payments, and food delivery in natural language -- it's playing a bigger chess game: pre-building an authorization system for the Agent era.

This is a key issue many haven't recognized. When an Agent makes decisions on your behalf, it needs your authorization: how much of your money can it spend? Which account information can it access? Within what scope can it make autonomous decisions? If your Agent calls another service's Agent to complete a task, how are permissions passed? How is liability defined?

Alipay sees this problem. If all service entry points are controlled by external Agents (like phone-makers' Agents, third-party standalone Agents), Alipay degenerates into a pure backend payment tool -- users don't see you; they only "pass through" at payment time. But if Alipay becomes the mandatory authorization node when Agents call payment, finance, and lifestyle services, it stays at the center of the transaction chain.

Fundamental Restructuring of the Advertising System

The ripple effects of gateway migration will first hit a market worth over 500 billion RMB annually: internet advertising.

Mobile-era advertising logic is "impression real estate" -- splash ads, feed ads, search bidding; essentially buying placement on the "people seeking services" path. You open the app, and I put a billboard on the road you must take.

Agent-era advertising logic is completely different. When a user says "book me a flight to Shanghai," the Agent won't show you ads from 10 airlines to choose from yourself -- it directly gives you one option it considers "optimal." At that point, advertising is no longer about buying impressions; it's about buying "recommendation rights."

Who defines "optimal"? The platform behind the Agent. It's WeChat, Alipay, phone manufacturers, or future standalone Agent gateways. When Agents make choices for users, "recommendation" itself becomes the most valuable commercial resource.

This is also why WeChat and Alipay are so anxious -- if someone else takes the gateway, not only is service distribution lost, but the very foundation of the advertising system is shaken.

A2A Protocol: The "TCP/IP" of the Agent Era

Behind this war runs a hidden thread: the A2A (Agent-to-Agent) protocol.

In June, Google open-sourced the A2A protocol and transferred it to Linux Foundation governance. The latest version v0.3.0 supports AgentCard capability self-description, Task lifecycle management, sync/async/streaming interaction modes, and provides four SDKs: Python, JS, Java, .NET. WeChat has already opened Agent capabilities to phone manufacturers based on A2A, with Honor as the first implementation partner. Alibaba Cloud also launched AgentRun, a production-grade multi-Agent collaboration platform based on A2A.

A2A is to the Agent era what TCP/IP was to the internet, what HTTP was to the Web -- it defines how Agents discover each other, communicate, and negotiate tasks. When Agents on different platforms can converse through a unified protocol, scenarios like "your WeChat Agent orders takeout, your Alipay Agent processes payment, your Meituan Agent handles delivery" are no longer science fiction.

But protocols are open; gateways are exclusive. TCP/IP is free, but Google made money on search; HTTP is open, but Facebook built walled gardens on top. The A2A protocol solves inter-Agent communication, but "who the user's first sentence goes to" is a problem protocols can't solve -- that can only be fought over through product and ecosystem.

The Real Battlefield: Authorization and Trust

Back to the issue Alipay cares about most: authorization.

The biggest obstacle in the Agent era isn't technology; it's trust. Do you dare let an AI assistant directly operate your bank account? Do you dare let it decide which fund to buy? Do you dare let it complete a transaction worth thousands without secondary confirmation?

The answers to these questions determine how far Agents can go, and who wins this war.

Alipay has been doing payments for twenty years; its greatest asset isn't technology, but users' trust that "Alipay can handle my money safely." WeChat has been doing social for fifteen years; its greatest asset is users' habit that "WeChat understands my social relationships and daily needs." These two kinds of trust and habit are hard for any new Agent entrant to replicate in the short term.

But phone manufacturers are also watching hungrily. Huawei, Xiaomi, OPPO, vivo -- if the system-level Agent on the phone is good enough, why would users open WeChat or Alipay? Why not just talk to the phone? Honor was first to access WeChat's A2A protocol; it's both cooperation and probing.

Changes Ordinary People Will Feel

For ordinary users, this war won't arrive as a "declaration of war"; it will quietly seep into daily life.

It might be that after a version update, you notice an AI entry point in your WeChat chat, you say "order me a coffee," and it pops up a Luckin order page directly. It might be that the Alipay homepage gets "cleaner" because it no longer needs to display so many entries -- you just talk. It might be that your phone's system assistant starts completing tasks across apps instead of just setting alarms.

These changes look trivial individually, but they converge on one certain direction: over the next three years, how you interact with your phone will fundamentally change. Those colorful app icons on your phone may gradually recede behind the scenes, just like feature-phone keypads did.

Internet history proves repeatedly: every gateway migration reshapes the entire industry landscape. The browser era gave birth to Google and Baidu; the app era gave birth to WeChat and Douyin. What will the Agent era give birth to? No one knows the answer yet.

But one thing is certain: WeChat and Alipay's Agent war is just the opening act. A bigger storm is still ahead.

See you tomorrow.
