ByteDance readies Muse-style AI agent to extend its video edge

What is coming and why it matters

ByteDance is prepping an AI agent patterned on Meta's Muse, aiming to launch within weeks. The launch is meant to fortify its position in video AI, and the company hopes it will start bringing it closer to the top US labs as early as three years from now.

Meta rolled out Muse in September as a voice-first helper with an animated avatar, bundling the company's AI research into one agent. Muse is being distributed across Meta's hardware, including smart glasses, with a Muse Charm device on the way. Whether ByteDance will pair its agent with hardware is not yet known.

Inside the strategy and timelines

Zhang Yiming laid out the plan and priorities at a recent all-hands with the AI group, according to people familiar with the discussion. He believes ByteDance can ultimately contend at the frontier with Anthropic PBC and OpenAI, but said reaching that tier wouldn't be expected before 2029 or 2030.

Data is the sticking point. Zhang, 43, said Seed's LLMs are trained in advance on data sets far smaller - by orders of magnitude - than those tapped by frontier competitors. He also reiterated his view that ByteDance should avoid leaning on distillation, which uses outputs from larger models to train smaller ones, and instead commit to the longer road. He noted that peers such as Alibaba Group Holding Ltd., Moonshot AI and Z.ai Co. have drawn rebukes from White House officials and Anthropic CEO Dario Amodei over their use of distillation.

Where ByteDance leads and where it lags

ByteDance's clearest edge is in video generation. It has tapped its vast video library to build and monetize the Seedance series, a high-end video model that stepped into the gap after OpenAI shut down Sora. The broader effort is hefty, with plans earmarked to allocate up to $70 billion and scale Seedance into China's top video AI platform. Zhang's remarks provided an unusual window into how the entrepreneur behind TikTok and Doubao, China's most popular ChatGPT-like bot, is approaching the space, and reflect renewed ambitions in an arena the company helped pioneer but watched rivals like DeepSeek overtake.

On core language models, Seed is the only major AI contender in China that has not released an LLM reaching the upper tier of global benchmarks or opened its model weights for developers. The last big LLM update, Seed 2.1, came in June, when the team said, "There remains room for improvement in the most challenging open-ended tasks and cutting-edge research problem-solving." In August, the Financial Times said ByteDance was building a system with up to 10 trillion parameters, comparable in size to Anthropic's Claude Mythos. An emailed request for comment went unanswered by a ByteDance spokesperson.

People, safety and the build-out

ByteDance is among China's most assertive recruiters of AI talent and provides preferential equity to Seed researchers and engineers. Roughly 1,000 researchers and engineers make up the unit, which is headed by Wu Yonghui, brought on by Zhang from Google DeepMind in 2025. The group's remit extends past language, video, and image systems to include efforts in AI for robotics, virtual reality, and additional hardware.

October marked Seed's establishment of the first dedicated safety and alignment unit among major Chinese AI labs, and it recruited about 10 core researchers to staff it.

The bottom line for your portfolio

ByteDance is pressing its advantage in video while queuing up a consumer-facing assistant and pacing itself for a longer climb to the frontier. The investment plan, Seedance focus and talent strategy point to a bid to turn a dominant video position into broader AI competitiveness. Track the assistant's rollout, the cadence of upgrades beyond Seed 2.1, and any confirmation of that 10 trillion-parameter effort for signals on execution and staying power.
