Tencent Yuanbao

What it is

Tencent Yuanbao, also known as Yuanbao or WeChat Yuanbao, is an AI assistant app developed by Tencent. It is based on Tencent's Hunyuan model.^[1] The app offers search, chat, document processing and image generation.^[1] An AI assistant app is a consumer product in which users chat with a language model to ask questions, draft text or get help with tasks.

It is available on Android, iOS, Windows, macOS and the web, and as an official WeChat mini-program.^[1] Its website is yuanbao.tencent.com.^[1]

Origins

Tencent launched Yuanbao on 30 May 2024.^[1] It was built on the in-house Hunyuan large model, and it supports Simplified Chinese, Traditional Chinese and English.^[1] A long-text reading feature was added on 6 August 2024.^[1]

Main features

Yuanbao's features include search, chat, document processing and image generation.^[1] The long-text reading feature lets users work with lengthy text, and it was added on 6 August 2024.^[1]

On 13 February 2025 Yuanbao integrated DeepSeek-R1, so users could choose between Hunyuan and DeepSeek models.^[1] The Hunyuan-T1-Preview reasoning model was launched in Yuanbao in February 2025.^[2]

HY 2.0 was integrated into Yuanbao in December 2025,^[3] and Hy3 followed in July 2026.^[4]

Place in the field

In early 2025 Yuanbao's ranking rose sharply. On 22 February 2025 it passed Doubao to rank second on China's Apple App Store free-download chart.^[1]

Yuanbao has also had public incidents, which show that an assistant used by many people can produce outputs its maker did not intend. On 5 January 2026 users reported insulting replies from the app. Tencent said they came from a low-probability abnormal model output, not from humans.^[1]

In February 2026 Yuanbao ran a campaign that offered 1 billion yuan in cash red envelopes. WeChat blocked the campaign's sharing links because they induced users to share. Yuanbao changed the mechanism, and WeChat lifted the restriction on 8 February 2026.^[1]
