HarmonyOS Tencent Video Debuts On-Device A2A Agent

KEY FACTS

  • The HarmonyOS version of Tencent Video has become the first to integrate the openJiuwen A2A protocol, enabling direct interaction between the system's Celia assistant and in-app AI agents.
  • Users can query plot details, character backgrounds, and other information via Celia without leaving the playback screen.
  • Leveraging OnApp Chips foreground perception technology, Celia automatically identifies the current context to recommend trending episodes or variety shows.
  • The A2A architecture ensures data flows locally on the device, reducing cloud transmission to lower privacy risks and improve response speeds.

PHYSIX OBSERVATION

This marks a critical step in the HarmonyOS ecosystem's transition from 'app silos' to a 'system-level intelligence hub.' On-device A2A not only resolves the fragmented user experience caused by disjointed cross-app services but also redefines the balance between privacy and efficiency through localized data processing. For developers, standardized interfaces significantly reduce adaptation costs, signaling that future mobile OSes will truly possess the capability to uniformly orchestrate third-party Agents rather than serving merely as launchers.
