About the model

GLM 5.2 is the recent top model in the Chinese GLM lineup from Z.AI: reasoning, code and agent scenarios. It lays out detailed step-by-step reasoning for complex multi-stage tasks and holds a very large context, working confidently with lengthy documents and long conversations. The model reliably calls tools (function-calling) and is a good fit for autonomous agents and automation. It follows instructions and system prompts and behaves predictably in production systems. Its Russian is average.
