Tencent Hy3 Preview AI Model
In April 2026, Tencent unveiled a preview of its next-generation AI model, Hy3 (Hunyuan 3.0). This model is significant as it’s the first major output led by Yao Shunyu, a former core researcher at OpenAI, who joined Tencent as Chief AI Scientist in late 2025.
Key Highlights of Hy3-Preview:
- Leadership: Yao Shunyu, known for developing the Tree of Thoughts and ReAct frameworks at OpenAI, spearheaded the Hy3 project. His recruitment by Tencent was a high-profile move
- Architecture: Hy3 employs a Mixture-of-Experts (MoE) architecture, featuring 295 billion total parameters with only 21 billion activated during computation. This design aims for high efficiency and “fast-and-slow thinking”
- Performance & Benchmarks:
- Reasoning & Coding: It achieved a 74.4% score on SWE-bench Verified, a substantial improvement over its predecessor (Hy2’s 53.0%), making it competitive with top models like Claude Opus 4.6
- Mathematics: Hy3 ranked first among Chinese models in the 2026 Tsinghua University math Ph.D. qualification exam, scoring 88.4
- Agentic AI: A primary focus of Hy3 is its “agentic” capabilities, allowing it to perform complex, multi-step tasks with minimal human intervention
- Ecosystem Integration: The model is being integrated across Tencent’s platforms, including the Yuanbao chatbot, CodeBuddy, and the WeChat/QQ ecosystems
- Strategic Shift: This release is part of Tencent’s broader AI infrastructure “rebuild,” with the company committing to doubling its AI investment to over $5 billion in 2026
Pricing and Availability:
The Hy3-preview is available through Tencent Cloud’s TokenHub, priced at 1.2 yuan per million input tokens and 4 yuan per million output tokens.
