Quick Answer
Zhipu (Z.ai) builds the GLM model family and AI products including Z.ai, ZCode and AutoGLM. GLM-5.3 supports a 1M context window for complex software engineering and long-horizon agent tasks, and GLM-5V-Turbo is a multimodal coding model. AutoGLM is an agent model with autonomous planning, reasoning and execution.
Z.ai, from Zhipu AI, builds a full-stack GLM large model technology system, with models such as GLM-5.3, GLM-5V-Turbo and GLM-5-Turbo and the AutoGLM agent model, which plans, reasons and executes autonomously. Its MaaS platform offers all-modality model APIs, ready-to-use agent application APIs such as translation and PPT/poster generation, and a development suite with model fine-tuning and AI search tools. Its products also include ZCode, the official harness for GLM-5.3.
Z.ai describes GLM-5.3 as open-source SOTA for coding with a 1M lossless context for long-horizon tasks, and AutoGLM as an agent model with autonomous planning, reasoning and execution and continuous self-improvement.
