The official site also points to Tencent AI Studio for trial access.

- Use across Tencent products: according to the official site, Hunyuan capabilities are applied in Tencent Docs, QQ Browser, QQ, ima, Sogou Input, Tencent Video, WeChat official accounts, Tencent News, and Peace Elite, with related products including WorkBuddy (CodeBuddy), Yuanbao, and ima.
- Boundaries: model membership, names, and statuses should be checked against the live official documentation. The “preview” label on Hy4 preview means it is a pre-release offering, not a general-availability version. The queuing experience mentioned on the show reflects the participants’ experience at the time, not the current service state.

Discussion of Hunyuan on the show is concentrated in Weekly #001 (recorded in early September 2026).
In the opening model roundup, Yang Pan listed Hunyuan 4 Preview among the models released that week.
In the chapter “GLM 5.3 Flash 与 MiniMax H3” (“GLM 5.3 Flash and MiniMax H3”), Guizang said capable, low-cost models attract attention, “including Hunyuan 4 Preview, and the trial experiences on WorkBuddy that many people follow”, with Orange adding that the trial lasted two weeks. This is the show’s relay of the trial channels available at the time.
In the chapter “国内模型为什么突然加速发布” (“Why Chinese models suddenly accelerated their releases”), Xiangyang Qiaomu said he tried Hunyuan 4 Preview and Qwen 3.8 Max 0902 and “couldn’t find a really good test case”; Orange and Guizang felt the models were “all about the same”.
In the chapter “滚动发版之后，Benchmark 还有没有意义” (“After rolling releases, do benchmarks still matter”), Xiangyang Qiaomu judged that “Hunyuan is decent”, while noting his queuing experience — “their own cards aren’t enough for their own use; I queued at 8 a.m. and got position 4,000-something” — and observed the release cadence: “last month they released Hunyuan 3, this month it’s already Hunyuan 4, one version a month”. These are experiences and observations from the recording date. See the episode 001 chapter.
On talent movement, Yang Pan relayed that “Hunyuan hired another person from Z.ai, one of the 5.3 people” — an unverified industry rumor relayed on the show.
