❯ Tencent previews Hy4 and Hy4 flash with vision and stronger long-running task capabilities

A release previewTencent cloud chief Dowson Tong said at the October 29 Digital Ecosystem Summit that Hy4 and Hy4 flash would launch soon. IT Home, citing on-site reporting by the STAR Market Daily, said Hy4 is designed to improve long-running productivity tasks and reasoning efficiency relative to Hy4 preview, while introducing visual understanding. Both models remain announced forthcoming releases.

From long text to visual workflowsTencent released Hy4 preview on August 28 with a one-million-token context window for long inputs. The latest emphasis goes beyond input length to maintaining progress across multistep work. Vision adds a route for handling information in images, potentially allowing charts, interfaces and text to be interpreted within one task. Specific performance will depend on the capabilities documented at release.

Flash targets frequent practical useHy4 flash is positioned as a cost-efficient practical model inheriting Hy4’s vision and agent capabilities, with continued iteration through model-product co-design. Office assistants repeatedly retrieve information, make decisions and call tools, so costs accumulate across steps. A flagship model and a lighter version address different requirements for complex work and frequent service calls.

▮ SIGNALLong-running tasks, vision and a lighter variant on one roadmap show model design increasingly being organized around agents’ practical workloads.
