Doubao Agents and Mini-Apps, Explained

On 15 July 2026, Doubao stopped letting its users create agents. Not throttled, not restricted to paying subscribers — removed. Alibaba’s Qwen posted an equivalent notice the same day, and the reason was the same for both: a new set of Chinese rules on anthropomorphic AI services took effect that morning.

This is, as far as we know, the only case of a major assistant’s user-built agent platform going backwards rather than forwards. It is worth understanding properly — both for what it says about Doubao, and for what it says about building consumer AI in a market where regulation is a live product input.

What happened on 15 July

China’s Interim Measures for the Administration of Anthropomorphic AI Interactive Services (人工智能拟人化互动服务管理暂行办法) were promulgated as Order No. 21 on 10 April 2026 by five departments — the Cyberspace Administration of China, the National Development and Reform Commission, the Ministry of Industry and Information Technology, the Ministry of Public Security and the State Administration for Market Regulation. They took effect on 15 July 2026.

That day, Doubao stopped allowing users to create custom 智能体 — agents — in its app, telling users that after 15 October 2026 agent-related data would be handled under the privacy policy. Alibaba’s Qwen (千问) app showed an equivalent “agent service going offline” notice the same day. ByteDance pointed its users to a separate product, Maobox (猫箱), to create new agents.

Two of China’s largest assistants withdrew the same feature on the same day, in response to the same instrument. That is about as clear a demonstration of regulatory causation as this industry produces.

What the rules actually require

The measures are not a ban on agents. They are a set of obligations that a user-generated persona platform is structurally hard to satisfy.

• Article 18 — providers must take effective measures to indicate to users that they are interacting with an AI service rather than a natural person, and must prompt users once continuous use exceeds two hours.
• Article 14 — providers may not offer virtual relatives, virtual companions or other virtual intimate-relationship services to minors, and must obtain guardian consent for under-14s.
• Article 16 — minors’ sensitive personal information may not be used in model training.
• Article 22 — a security assessment is triggered once a service exceeds 1 million registered users or 100,000 monthly active users.

Read those together and the problem becomes obvious. A platform where any user can build a persona is a platform where the provider cannot know in advance what personas exist. Guaranteeing that none of them constitutes a virtual companion offered to a minor, when you did not write them and cannot review them at the scale of a 382-million-user app, is not a moderation problem you solve with a filter.

The scale threshold makes it concrete: at 382 million monthly active users in June 2026 per QuestMobile, Doubao is roughly 3,800 times past the point at which a security assessment is required. Nothing about these obligations was hypothetical for it.

What is left inside Doubao

The withdrawal removed user-created agents. ByteDance’s own agents remain, and the best-documented of them is a good illustration of what a first-party agent looks like.

Owen (英文外教Owen) is Doubao’s English-tutor agent. It had been used more than nine million times inside the app by May 2025, when ByteDance’s Ola Friend earbuds gained the ability to voice-summon it directly for real-time conversation. Owen offers English conversation, read-aloud drilling and bilingual feedback, using practice formats such as movie dialogue and word puzzles, across everyday, workplace and travel scenarios. It is switched on from the app’s settings under the earbuds’ Doubao agent options.

A first-party agent is straightforwardly compliant in a way a user-built one is not: ByteDance wrote it, knows what it does, and can attest to its behaviour. That asymmetry is the whole story of what survived. Our English article covers Owen in more detail.

The agent ByteDance now charges for

Here is the twist that makes this more than a story about a lost feature. Nine days before the agent withdrawal, ByteDance launched a paid tier whose distinguishing capability is — an agent.

Doubao Pro launched on 24 June 2026 at CNY 68, 200 and 500 per month in mainland China. Beyond quota, what it adds is an agent-driven office task mode (办公任务模式) on the PC client. After the user explicitly authorises local-computer access, it can drive local applications, the browser and files — organising and sorting local material, processing documents, filling forms — and produce Feishu online documents, spreadsheets and presentations, plus scheduled tasks and production-grade web app generation.

So agents did not leave Doubao. The kind of agent changed. Out went user-authored personas — conversational, anthropomorphic, exactly what the new measures target. In came a first-party tool that operates software on your behalf, which the anthropomorphic-AI rules do not touch because it is not pretending to be a person. Our pricing article covers what that buys.

That shift is visible across ByteDance’s model line too. The Doubao-Seed-2.0 series announced in February 2026 was described as three general multimodal agent models, and the 1.8 release in December 2025 was positioned around stronger agent capability. The company is going hard at agents — just not at agents that behave like characters.

The most agentic thing ByteDance ships

The furthest expression of this is not in the app at all. It is the Doubao Phone Assistant, a system-level agent that operates the phone itself, launched as a technical preview on ZTE’s nubia M153 on 1 December 2025 and continued in the nubia NaviX Ultra announced in July 2026.

It has been an instructive experience for everyone involved. Within days of the M153’s launch, Caixin reported that several of China’s most-used apps — WeChat, Taobao, Alipay and Honor of Kings — had restricted the assistant, in what it framed as an ecosystem backlash over OS-level app control, data access and fairness. Tencent denied taking direct action against WeChat. On 9 December ByteDance said it would itself curb the assistant: restricting automated operations used to farm points or rewards across apps, further limiting AI operational capacity in banking and payment apps, and suspending AI use in certain competitive gaming scenarios.

Security research has been pointed too. DARKNAVY’s March 2026 analysis identified a GUI time-of-check-to-time-of-use race window opened by the two-to-three-second cloud inference delay with no rollback if the interface changes mid-execution, and prompt injection via on-screen text that let researchers extract the system prompt. The full story is here, and our safety article covers the research.

What Doubao’s agents were before this

It is worth recording what was actually lost, because English coverage of Chinese assistants rarely documents the agent layer at all.

Agents inside Doubao were user-authored characters and assistants — 智能体 — that other users could then talk to. That format has been a large part of Chinese consumer AI: a persona with a defined role, personality and knowledge, more conversational companion than tool. ByteDance’s minors notice, effective 26 August 2025, gives an oblique confirmation of scale by listing third-party agents among the features automatically disabled for users in minors mode — a protection you build when third-party agents are numerous and varied enough to be worth protecting children from.

ByteDance also runs Coze, a separate agent-building platform, and its Seed models power more than fifty ByteDance applications including Coze and Jimeng. So agent tooling is not new to the company, and the July 2026 withdrawal was specifically about agent creation inside the mass-market consumer assistant rather than about agents as a product line.

That distinction matters when you read the announcement. ByteDance did not exit agents. It moved them out of the app where the compliance burden was largest and into products designed to carry it.

What this episode is actually evidence of

It would be easy to file this as “Chinese regulation kills feature” and move on. That reading is too simple, and it misses what is genuinely useful about the case.

First, it shows that feature comparisons between Chinese and Western assistants are not comparing like with like. A capability absent from Doubao may be absent for reasons that have nothing to do with engineering capacity or product judgement. Anyone scoring assistants on feature-list length should know which absences are choices and which are constraints. Our comparison table flags this row for exactly that reason.

Second, it shows the direction of travel is toward tool-use agents rather than persona agents. The rules restrict AI that pretends to be a person; they do not restrict AI that fills in a form. ByteDance’s response — withdraw the personas, sell the office assistant — reads as a straightforward reading of where the permitted ground is.

Third, it is a reminder that in this market a product’s roadmap has an author who does not work at the company. When a Doubao feature disappears, regulation is at least as likely an explanation as strategy, and we treat it that way throughout this site.

How this compares with Western agent platforms

For context, here is where the same capability sits elsewhere as of August 2026.

The shape of that table is the point. Two of the six lost the feature on the same day for the same reason, one never offered it, and the three that have it are all outside the Chinese regulatory perimeter. If you were scoring assistants by feature count you would mark Doubao down here — and you would be measuring jurisdiction rather than product.

It is also worth noting what the Chinese rules are actually aimed at. The measures target anthropomorphic interaction specifically: services that present as a person, that a user might form an attachment to, that a minor might mistake for a relationship. Custom GPTs are mostly not that — they are task wrappers with a system prompt. But a rule written broadly enough to catch companion apps will catch persona platforms too, and a provider at Doubao’s scale cannot argue the distinction case by case across millions of user-authored agents.

What we could not verify

• We have not used Doubao’s agents. The app requires an account registered through one of ByteDance’s four supported routes and is listed in three App Store storefronts. Everything here comes from ByteDance’s notices, the published measures and reputable reporting.
• We could not assess Maobox. ByteDance directed users there, but we could not verify what it offers, how it handles the compliance obligations, or whether it is available outside mainland China.
• The scope of the withdrawal is not fully documented. We can confirm that user creation of new agents stopped and that agent data would fall under the privacy policy after 15 October 2026. What happened to previously created agents in the interim is not something we could establish.
• Third-party agents are lightly documented. Doubao’s minors notice refers to third-party agents being disabled in minors mode, implying they exist, but we found no published catalogue.
• Office task mode is announced, not tested. Its capabilities are ByteDance’s description; we have not run it, and it requires a paid mainland Chinese subscription.
