Tencent WorkBuddy Extends Free Access for Hy3 and Hy4 Preview Models
Tencent WorkBuddy has extended free access for its Hy3 AI model and free night-time usage for the Hy4 preview model until October 31. Additionally, new users who activate Hy4 preview for the first time before October 10 will receive a 14-day daily free credit allocation. This promotion lowers the barrier for users to test Tencent's latest Hunyuan-series language models directly within their office AI workflows. It reflects ongoing user acquisition tactics among Chinese tech giants competing in the enterprise desktop AI agent market. The free night-time quota for Hy4 preview operates between 23:00 and 8:00 daily, while usage during standard hours consumes regular platform credits. Furthermore, Hy4 preview is currently text-only, so executing multimodal tasks like image or video generation will automatically route to specialized models and deduct standard credits.
## BACKGROUND
Tencent WorkBuddy is an all-in-one AI office desktop workbench developed by Tencent Cloud to assist with research, coding, and document analysis. The "Hy" models correspond to Tencent's Hunyuan large language model ecosystem, which underpins the company's generative AI offerings.
