Hy4 is available in Tencent Cloud ADP

Tencent Cloud ADP says the full version of Hunyuan Hy4 was released on November 4 and is now available in its smart workbench. Users can select the model there, and calls to Hy4 through ADP are being offered at half price through December 31, 2026. The promotion applies to model calls made through ADP. The ADP report also points readers to a separate announcement from Tencent Hunyuan.

Compared with Hy4 Preview, the full version expands the scale of both pretraining and post-training. Tencent says it has added visual understanding for the first time and strengthened instruction following, long-document understanding, long-horizon tasks and deep research. Those changes accompany Hy4’s support for work involving images, charts, commands, graphical interfaces and tools.

Visual understanding and computer operation

Hy4 can analyze images and charts, then combine command-line use, graphical interfaces and tool calls to carry out multi-step tasks. The description presents these abilities together as visual understanding and computer operation. Tencent’s model service supports a context window of about 1.05 million tokens and a maximum output of 65,536 tokens per call. The actual limit depends on the access point, so users may see different limits depending on how they use the service.

The release report also describes changes in areas beyond visual tasks. For frontend and game development, Hy4’s GameDev evaluation result improved by 19.1% compared with Preview, while its GameLogic result improved by 9.8%. The report gives these as changes against the Preview version, rather than as absolute scores.

Reported results in finance and research

Tencent Financial Technology FiT conducted a joint test covering 579 financial tasks. Hy4 scored 3.04 out of 4, placing it first among the participating open-source models in that particular task set. In a separate Hunyuan-focused search test, the reported hallucination rate declined from 15.76% to 5.45%.

Hy4 also ranked first among participating open-source models in the TenureTrail research evaluation. The report says the evaluation data come from specific task sets and test environments, and that actual performance can vary with the task and configuration.

Building agents with Hy4 in ADP

In the ADP smart workbench, users can choose Hy4 and describe a business need in natural language to begin building an agent. The report names customer service, knowledge question answering and internal operations as possible use cases. Teams can configure permissions, evaluate an agent’s results and publish it to a business entry point.

For tasks that need to keep running in the cloud, ADP’s Agent Harness can be started or stopped as needed. It also supports resuming a task from a checkpoint and reviewing its run records. Separately, ADP advertises a Double 11 promotion in which new customers receive at least 50% off their first package purchase. That package promotion is distinct from the half-price offer on Hy4 model calls, which the report says runs through December 31, 2026.
