Zhang Yiming reportedly told staff that ByteDance needs years to challenge leading US AI labs, even as the TikTok parent prepares a personal agent for release within weeks. Its consumer reach and video strengths have yet to translate into frontier language models.
ByteDance, the Chinese technology company behind TikTok, is preparing a personal AI agent while its co-founder warns that matching the leading US model developers remains a multiyear project. The contrast puts a near-term product launch alongside a much less certain research timetable.
Zhang Yiming, ByteDance’s co-founder and former chief executive, told its AI staff at a recent all-hands meeting that the company could compete at the cutting edge with AI developers Anthropic and OpenAI, but would need until at least 2029 or 2030, according to an account relaying an unnamed-source report about the meeting. The same reporting describes plans to release an agent similar to Meta’s Muse in the coming weeks.
Zhang founded ByteDance in 2012 and used AI recommendation engines to build the news service Toutiao and video app TikTok. He announced his handoff of the CEO role to Rubo Liang in 2021, with a shift toward longer-term strategy. His reported intervention now concerns research priorities as well as the next consumer product.
The accounts of the meeting share a single underlying report based on unnamed sources; they do not constitute separate confirmations. ByteDance did not respond to the original request for comment, according to the available accounts. The timetable is therefore a reported internal assessment, not a public launch commitment or a guarantee of eventual parity.
ByteDance already has Doubao, described in the reporting as China’s most popular ChatGPT-style chatbot. Yet its Seed language-model effort reportedly has neither released a model ranking among the world’s best on benchmarks nor made its model weights available to outside developers. Its last major language-model update was Seed 2.1 in June.
Those are distinct measures of progress: a popular application demonstrates demand, while benchmark performance and access to model weights concern capability and external scrutiny. The available accounts do not supply benchmark scores or a common evaluation method that would quantify the current gap.
Zhang reportedly identified data as a central concern, saying Seed’s pre-training datasets were orders of magnitude smaller than those used by frontier rivals. No comparable dataset counts were disclosed in the accounts, so that description cannot responsibly be converted into a precise ratio.
He also reiterated that ByteDance should avoid distillation—using a larger model’s outputs to teach another model—and focus on longer-term goals. The stance comes amid criticism from White House officials and Anthropic’s chief executive of alleged reliance by other Chinese labs on leading American models. Those criticisms concern competitors; they do not establish misconduct by ByteDance.
Seed reportedly employs roughly 1,000 researchers and engineers under Wu Yonghui, recruited from Google DeepMind in 2025, with preferential equity packages for the unit. It established a dedicated safety and alignment team in October, described in the accounts as a first among China’s major AI labs. Staffing, incentives and governance show how the company is organizing the effort; none supplies a measure of frontier performance.

The strongest counterweight to the language-model shortfall is video. ByteDance’s Seedance models turn its large video pool into a commercial video-generation platform. The reports describe an existing competitive strength, including an opportunity after OpenAI discontinued its Sora video product.
The accounts also cite spending of as much as $70 billion, but describe its scope differently: the infrastructure account frames it as AI infrastructure, while another account ties it to making Seedance China’s leading video AI platform. They provide no common spending period. The figure indicates reported ambition rather than a sufficiently specified budget for comparison with rivals.
There is firmer detail on financing. A September report based on people with direct knowledge said ByteDance had secured a $29.6 billion loan from nearly 30 banks, coordinated by Citigroup and JPMorgan, with signing expected shortly. The dollar-denominated facility was unsecured, requiring no asset or share collateral, and had an initial three-year term with options to extend for two more years.
The facility grew from a $20 billion target after strong lender demand—a 48% increase in the proposed borrowing amount. Chinese banks subscribed to more than 60% of the total, one source said. The lack of collateral reflects lenders’ confidence in ByteDance’s creditworthiness; it is not a measure of its models’ performance.
ByteDance told lenders the money was for general corporate purposes; the sources said it would mainly support AI plans. One source said the loan would fund projects outside China and that ByteDance had binding agreements to buy capacity from data centers under construction in Southeast Asia. Contracted capacity is distinct from completed infrastructure.
The September financing report also described June talks to buy inference chips from Shanghai-based Iluvatar CoreX and consideration of a similar deal with Baidu. Inference runs models to produce outputs; it is separate from the pre-training data problem. Neither the loan amount nor the reported spending plan establishes the forthcoming agent’s cost per task.
Meta, the company behind Facebook, Instagram and WhatsApp, introduced Muse in September. The meeting accounts describe it as a voice-based assistant with an animated avatar, with distribution through smart glasses and a forthcoming Muse Charm device. Whether ByteDance plans accompanying hardware remains unknown.
The competitive standard extends beyond an avatar. In its product announcement, Meta says Muse operates with a dedicated virtual computer and browser, works across connected apps, and handles tasks such as email and travel booking. Meta says it seeks approval before actions such as sending an email or making a purchase. Users can choose which services to connect and revoke access, Meta says. These are company descriptions, rather than independent evidence of reliability.
Meta says Muse is rolling out in the US on iOS, Android and the web, with AI glasses to follow. It describes most uses as free, with subscriptions for people who want to do more, but specifies no subscription prices in the announcement. ByteDance will therefore face an existing free offering as well as a competing interface.
A separate account of Muse’s reception puts downloads above 10.4 million by mid-October and relays Meta CEO Mark Zuckerberg’s statement that its family of apps reaches 3.64 billion daily users. The latter figure covers Meta’s apps, not Muse’s active users; downloads do not establish continuing use or profitability. The account also relays a warning from investor Gene Munster of Deepwater Asset Management about Muse’s cash consumption, without providing a cost estimate.
For ByteDance, the next material evidence will be a released product: its supported tasks, permissions, availability, price and reliability. The available reporting leaves those details unresolved. A launch could establish a foothold in personal agents while the harder question—whether Seed can close its underlying model gap—remains open on Zhang’s much longer timetable.
