Honor's YOYO Claw agent now runs on Zhipu's GLM-5.3
China's device makers are plugging frontier models straight into their agents, and Honor just became the first big name to ship Zhipu's new flagship.
Honor's cross-device AI agent YOYO Claw now runs on Zhipu's GLM-5.3, the model the lab released Thursday — making Honor the first major device maker to adopt the new open-weights model. The company's all-scenario software lead, Xi Yingjun, announced the integration on the evening of August 14, calling it a full upgrade of Claw's "shrimp brain." YOYO Claw is Honor's agent for its PCs and tablets: it entered closed beta in late March, debuted at Honor's April PC event, executes tasks across Honor devices, and can connect to OpenClaw agents running on third-party hardware. The upgrade lands a day after Zhipu shipped GLM-5.3 — same base model as GLM-5.2, with every gain coming from post-training scaling.
Zhipu claims the new model pushes coding ability 50% above GLM-5.2 and tops the open-source leaderboard on Terminal Bench 3.0 and Agents' Last Exam (CLI). It also beefs up the security side: in white-box code review and vulnerability discovery, Zhipu says GLM-5.3 performs on par with Mythos 5, its frontier closed model. Weights are due to open two weeks after release, once safety evaluation and hardening wrap up. We covered the launch and its security profile on Thursday — Zhipu's GLM-5.3 ships with 'emergent' cyber capabilities.
Why it matters: integrations like this are how Chinese labs convert benchmark wins into installed base. Honor is a top-five global phone maker, and it chose a domestic model for an agent that spans PCs and tablets — a signal that hardware vendors now want agentic models with coding and security chops, not just chat. It also gives Zhipu a distribution channel that pure API sales can't match, and puts a model with demonstrated offensive-security capability directly into consumer devices. Watch whether other device makers follow before the weights go public in two weeks.
