Tiangong

Tiangong is Kunlun Wanwei's consumer AI app — Chinese-language chat, an AI search product and music generation under one free roof, opened in April 2023 and run on the company's own 天工/Skywork models. The vendor's page leads with a different slogan now, “AI办公智能体先行者” (roughly, the office-agent pioneer), which tells you where the investment is going: the chatbot is the entry point, not the pitch. Public records still trace the chat line from 天工 1.0 through 大模型 4.0 with reasoning-style updates and SkyMusic on the audio side, while Kunlun's GitHub publishes MIT-licensed research from the same effort — Skywork-R1V for vision-language reasoning (last touched 29 July 2026), DeepResearchAgent (May 2026), and a Skywork-Skills package spanning AI search, deep research and AI music (April 2026).

A reader outside China should assume friction: the interface is Chinese, registration is built around a mainland mobile number and a real-name flow, paid tiers do not take international cards, and your data stays onshore. Where it loses is depth — the frontier-reasoning conversation in China now runs through DeepSeek, Qwen and Kimi, and Tiangong is a wide, shallow suite rather than the strongest model or the best long-document tool, with 天工, Skywork and Mureka branding blurring which claim belongs to which product. Pick it if you already live in the Chinese app ecosystem and want chat, search and songs in one free client; skip it as a primary assistant.
