Tencent Opens Global Access to Hy3, Its Long‑Context Mixture‑of‑Experts AI Model

Overview

• Tencent rolled out Hy3 to developers, enterprises and users through WorkBuddy, Tencent Design Miora and Tencent Cloud TokenHub on Wednesday, making the model broadly available beyond its July launch.
• WorkBuddy users get free Hy3 access through 31 August 2026 and developers can call the model via published OpenRouter API pricing that starts at US$0.1288 per million input tokens.
• Hy3 is a Mixture‑of‑Experts model with 295 billion total parameters and 21 billion active parameters that supports context windows up to 256,000 tokens to handle long, multi‑step workflows.
• Tencent is distributing Hy3 under an Apache 2.0 license on developer hubs such as Hugging Face and ModelScope and is expanding regional access through partners like Cafe24 and Metelix.
• Tencent reports strong early traction and internal gains for Hy3, citing a 68x increase in API calls, top OpenRouter usage rankings and higher task success and speed in WorkBuddy, though those figures come from company evaluations and lack independent verification.
