Why Chinese AI researchers picked X as their office

A Moonshot AI cofounder runs a personal-life X account alongside lab posts. A DeepSeek researcher who reportedly cannot leave China ships follow-up ideas to Western peers in public. After DeepSeek R1's January 2025 virality, X has become the de facto public venue where Chinese AI researchers do their visible thinking, and that visibility is rewriting the Black-Box-China-AI story for anyone willing to scroll.

Moonshot AI, the maker of the Kimi K-series of models, is now the most active Chinese AI lab on the platform, with roughly 30 self-identified affiliated accounts counted by the author of a new Wired dispatch. Two cofounders post regularly, mixing lab announcements with hobby photos and life updates. Technical staff share papers, recruitment posts, and follow-up work to releases. The feed reads more like a startup's open notebook than a press channel.

"What changed is the platform itself," says Meng Fanqing. Meng began actively posting on X in mid-2025 and now calls it "the best community" for AI discussion. He is not alone: executives and engineers at Minimax and Z.ai are visibly present. Several DeepSeek employees, reportedly unable to leave China because their passports have been held, per The Information, still post on X and use it to advertise open roles.

The domestic alternatives have thinned. Zhihu, China's Quora-style Q&A site, pivoted toward fiction and low-quality content after 2020; mathematician Deng Yu, the 2006 Fields Medal winner, publicly quit in 2018. Xiaohongshu reaches an urban, educated crowd but skews toward lifestyle and gossip. When a March Moonshot paper landed, a current Moonshot researcher told Wired, the technical discussion happened on X while Zhihu and Xiaohongshu filled with chatter about the authors' backgrounds.

Independent AI analyst Tiezhen Wang, a former Hugging Face researcher, advised Moonshot in 2025 to put more researchers forward on social media. The reasoning is the same as a finance associate learning to write a thread: X is branding infrastructure, and a steady cadence of public reasoning compounds into reputation. Wang argues the shift fills a gap left by OpenAI and Anthropic, whose own researchers have grown more secretive in the past year. "Western audiences used to rely on translations of Chinese AI blogs like Su Jianlin's kexue.fm to follow the work," Wang says. "Now they get first-hand voices."

R1's January 2025 release created a permission slip. Foreign press had to cover Chinese models seriously; researchers had a reason to be readable in English. The cohort that had been building on Chinese-language channels, Su Jianlin's blog, internal group chats, conference talks, saw a path to a global audience. X is the only English-language platform that lets them post without a paywall, build a thread, and be argued with in public by peers at Meta, Anthropic, or DeepMind.

A new paper from a Moonshot engineer can now be screenshotted, quoted, and questioned on X within hours, before it reaches a conference review queue. A job post at Z.ai sits next to a thread from a DeepMind researcher asking whether the role is real. The first examples of that record are messy, fast, and largely unmoderated.

Counts like "30 Moonshot accounts" come from a single author's scroll, not a measured platform tally. Moonshot did not respond to a request for comment on its social strategy. Some accounts post under pseudonyms; the cohort that matters most, the people actually writing the next Kimi or DeepSeek release, is still a subset of the whole. For the first time, though, that subset is in the open, in English, on one platform, and the way to find them is to follow the people who are already there.

The next test is whether the openness survives the geopolitical weather. R1's catalyst moment was a model release; the next one could be a platform restriction, a regulator's directive, or a single high-profile account going dark. For now, the public square is open. The Moonshot cofounder's hobby photos sit next to a Kimi technical thread, and a researcher who cannot leave the country can still answer a question from a Western peer on the platform. That is the new shape of Chinese AI in public.
