Tencent Yuanbao (Chinese: 腾讯元宝; pinyin: Téngxùn Yuánbǎo) is a consumer-facing artificial intelligence assistant application developed and operated by Chinese technology company Tencent. The app was first released on 30 May 2024 as Tencent's flagship public-facing front end for its in-house Hunyuan family of large language models.[^1] Yuanbao combines conversational chat, web search, document analysis, image generation, and "deep research" workflows, and it is distinctive among Chinese AI chatbots for its tight integration with the WeChat super-app ecosystem.[^2] In February 2025 Tencent added access to the DeepSeek-R1 reasoning model alongside Hunyuan inside Yuanbao, a high-profile decision by a major Chinese internet company that helped briefly propel the app to the top of Apple's China iOS free-app chart in early March 2025.[^3][^4]

Tencent released Yuanbao on 30 May 2024, marking the company's first dedicated standalone AI assistant app and its formal entry into the consumer chatbot race after rivals such as Baidu's ERNIE Bot, Alibaba's Tongyi Qianwen, ByteDance's Doubao, and Moonshot AI's Kimi had already shipped public apps.[^1][^2] At launch Yuanbao ran on Tencent's proprietary Hunyuan foundation model. Tencent's announcement described Hunyuan as a trillion-parameter Mixture of Experts (MoE) large language model whose pre-training corpus had been expanded to roughly 70 trillion tokens.[^1][^2]
The product was branded explicitly around Hunyuan: marketing emphasised that Yuanbao was the consumer expression of Tencent's foundation-model investment, in contrast to enterprise products such as the Hunyuan API on Tencent Cloud.[^2] Yuanbao initially launched with text and voice chat, document and URL summarisation, image understanding, an agent gallery with task-specific personas, and a search feature that uniquely indexed WeChat Official Account ("Gongzhonghao") articles and Video Channel ("Shipinhao") content, a corpus that is not crawlable by standard search engines.[^1][^2]
In July 2024 Tencent upgraded Yuanbao with a "Deep Search" mode that performed multi-step web retrieval and a long-document analysis workflow targeted at academic papers, financial reports, and research notes.[^5] The deep-reading mode supported uploads of multiple files (including PDF, Word, Excel, PowerPoint, and TXT), processed long contexts, and produced structured summaries with extracted figures.[^5]
On 13 February 2025 Tencent added access to the recently released DeepSeek-R1 reasoning model inside Yuanbao, exposing a "deep thinking" toggle that let users send queries to either Tencent's own Hunyuan-Thinker model or the full-capacity DeepSeek-R1.[^3][^6] The DeepSeek-R1 integration inside Yuanbao supported web search and indexed Tencent ecosystem sources, including WeChat Official Account posts and Video Channel content.[^3] The move was notable because Tencent, one of China's largest internet companies and itself a foundation-model developer, chose to put a competing open-weights model from a smaller lab on equal footing with its own.[^6][^4]
Tencent backed the launch with an aggressive marketing campaign. According to industry tracking firm Qimai Data, Yuanbao climbed to the No. 2 spot on the China iOS App Store free-app chart on 22 February 2025, displacing Doubao, before reaching No. 1 on 3 March 2025, displacing DeepSeek's own app.[^4][^7] ByteDance's Doubao slipped to fourth place that week.[^4][^7] On 4 March 2025 Bloomberg reported that Tencent had become the first major Chinese tech firm to overtake DeepSeek on the country's most-downloaded free iPhone app chart following the R1 integration, characterising it as a milestone in the intra-China AI race.[^7]
A preview of Tencent's own reasoning model, Hunyuan-T1 (sometimes branded Hunyuan-Thinker-1), launched first inside Yuanbao in mid-February 2025 and was rolled out as a stable release on 21 March 2025.[^8][^9] Hunyuan-T1 is built on the TurboS base, which Tencent describes as the first ultra-large-scale Hybrid-Transformer-Mamba MoE language model.[^8] After T1 shipped, Yuanbao's reasoning toggle exposed both T1 and DeepSeek-R1 (later DeepSeek-V3-0324) as selectable backends, and the app retained its non-reasoning Hunyuan default for routine conversational queries.[^9][^10]
Tencent's South China Morning Post coverage characterised the T1 launch as a direct response to DeepSeek-R1: T1 priced input at 1 yuan and output at 4 yuan per million tokens, matching DeepSeek-R1's daytime API rates, and reported MMLU-PRO and MATH-500 scores close to DeepSeek-R1's published numbers.[^9]
Through 2025 Tencent progressively folded Yuanbao deeper into WeChat. Beyond its existing WeChat mini-program, on 16 April 2025 WeChat let users add an official "Yuanbao" account as a contact and interact with it inside the chat UI, supporting text, image, and document inputs without leaving the messenger.[^11][^12] Tencent presented the integration as a step toward an in-WeChat agent: Yuanbao could process attachments shared inside chats and set timed WeChat service-notification reminders.[^11] Coverage in South China Morning Post framed the feature as part of Tencent's strategy to lock AI usage inside its super-app rather than competing on standalone-app downloads.[^12]
Tencent has continued to update Yuanbao's backing models and UI. In September 2025 Tencent open-sourced HunyuanImage 3.0, a multimodal native image generator that subsequently rolled out inside Yuanbao alongside earlier Hunyuan-DiT-based image generation.[^13] On 20 March 2026 Tencent updated the Yuanbao app icon with an anthropomorphic redesign that added "eyes" to the original ingot ("yuanbao" literally refers to a traditional Chinese gold or silver ingot) glyph, part of a broader push to make the assistant feel more like a companion than a tool.[^14]
Yuanbao does not develop its own foundation model. Instead it routes user requests to a portfolio of backends, selectable in some flows by the user and in others by Tencent's router:
Tencent's official Hunyuan-T1 page reports the following benchmark scores for the deep-reasoning model that powers Yuanbao's "Hunyuan Thinker" mode:[^16]
| Benchmark | Hunyuan-T1 score |
|---|---|
| MMLU-Pro | 87.2 |
| GPQA Diamond | 69.3 |
| MATH-500 | 96.2 |
| LiveCodeBench | 64.9 |
| ArenaHard | 91.9 |
Tencent positions these results as approximately on par with DeepSeek-R1 and competitive with OpenAI o1, while noting Hunyuan-T1's Mamba-based throughput advantage at long context lengths.[^8][^16]
Yuanbao's product surface exposes several distinguishable capabilities:
Yuanbao entered the Chinese AI assistant market roughly a year after the first wave of post-ChatGPT Chinese chatbots and trailed ByteDance Doubao, Baidu ERNIE Bot, and Alibaba's Tongyi family in cumulative user base for most of 2024. Its first sustained surge in downloads followed the February 2025 DeepSeek-R1 integration. According to AIcpb.com data cited by South China Morning Post, Yuanbao's daily active users (DAU) rose from "hundreds of thousands" in early February 2025 to roughly 3 million by late February.[^4] Yuanbao reached No. 2 on Apple's China free-app chart on 22 February 2025 and No. 1 on 3 March 2025 per Qimai Data, surpassing DeepSeek's own app and Doubao.[^4][^7]
The Chinese consumer AI assistant field as of 2025 and 2026 included several major standalone apps and embedded experiences. Yuanbao's positioning differs from each in distribution model.
| App | Operator | Primary backing model(s) | Distinguishing feature versus Yuanbao |
|---|---|---|---|
| Doubao | ByteDance | Doubao foundation models | Highest standalone DAU in 2025-2026; integrated into Douyin and ByteDance's content stack[^18] |
| Ernie Bot / Wenxiaoyan | Baidu | ERNIE family | Search-engine integration; "Wenxiaoyan" rebrand in 2024 positioned it as a search assistant[^19] |
| Tongyi Qianwen / Quark | Alibaba / Alibaba Cloud | Qwen models | Strongest enterprise and developer reach via Alibaba Cloud and open Qwen weights |
| Kimi | Moonshot AI | Moonshot Kimi models | Long-context document workflows; standalone consumer app |
| ChatGLM | Zhipu AI | GLM models | Hybrid open-weights and consumer app; academic origins at Tsinghua |
| DeepSeek (consumer app) | DeepSeek | DeepSeek-V3, DeepSeek-R1 | Free, open-weights model; minimal product layer |
| Yuanbao | Tencent | Hunyuan, Hunyuan-T1, DeepSeek-R1/V3 | WeChat-native distribution, in-chat contact, Official Account/Video Channel search |
Reporting in 2026 from NPR and other outlets placed Doubao first by monthly active users in China, with Ernie Bot, Quark, Yuanbao, and Kimi rounding out the top five, while DeepSeek's standalone app continued to draw a large share of free-app downloads.[^18] Specific MAU and DAU numbers vary substantially between sources and Tencent has not published primary figures, so absolute totals are omitted here in line with the article's sourcing rules.
Multiple analysts have argued that Yuanbao's structural advantage is not its model quality but Tencent's distribution control through WeChat, which has more than one billion monthly active users.[^12][^2] WeChat integration takes several forms:
Inside its product surface, Yuanbao is positioned as a general-purpose assistant. Documented use cases discussed in Chinese press coverage and Tencent product pages include:
Tencent has marketed Yuanbao primarily to Chinese-language consumers; the app is not the primary offering Tencent uses to court enterprise developers, who interact with Hunyuan through Tencent Cloud APIs.[^2]
Yuanbao has drawn several pieces of public criticism and faces structural limitations.
