Chinese start-up Zhipu AI, also known as Z.ai, has launched a framework for using its tools in semi-autonomous coding agents, as it ramps up competition with Anthropic.

The company, which trades on the Hong Kong stock exchange as Knowledge Atlas Technology – the English rendition of its Chinese name Zhipu Huazhang Keji – said the new ZCode harness would work with its latest mode GLM-5.2.

ZCode helps large language models such as GLM-5.2 execute tasks autonomously, allowing them to be used to help independently collaborate on programming projects.

Such tools have seen a surge in popularity since Anthropic’s Claude Code became a viral success last autumn.
