Zhipu GLM Agent
Tsinghua-spinoff Zhipu (rebranded internationally as Z.ai in July 2025) ships the GLM model line through the BigModel platform, with function calling, web search, knowledge-base retrieval and JSON output all available as tool/response options on the same chat-completion API; AutoGLM is the consumer agent built on top.
Description
Zhipu (Z.ai) is one of China's three biggest LLM providers and IPO'd on the Hong Kong Stock Exchange on 8 January 2026. Its GLM model line has been MIT-open-source since July 2025 (GLM-4.5 onward), with the latest GLM-5/5.1 and GLM-5V-Turbo positioned for agentic engineering, coding and long-chain execution. The BigModel chat-completion API supports tools: function calling, knowledge-base retrieval and web search are listed together as tool options, and structured output is selectable via response_format json_object. AutoGLM is the consumer agent application that uses voice commands to complete tasks on a phone and can self-execute operations exceeding 50 steps across applications.
Solution
Two surfaces. (1) BigModel chat-completion API: standard tools-loop where tools[] can include functions, knowledge-base retrieval, or web search; the model emits tool_calls, the caller executes, results return as tool messages; response_format json_object pins shape. (2) AutoGLM: hosted consumer agent that takes voice commands, plans multi-step actions, and self-executes >50-step workflows across smartphone apps.
Primary use cases
- function-calling agents over GLM hosted API
- RAG via knowledge-base retrieval and web search as built-in tools
- JSON-structured extraction via response_format
- consumer voice agent (AutoGLM) on smartphones
