Z.ai has introduced GLM-5.2, its latest flagship AI model designed for long-horizon coding and software engineering tasks. The model features a 1 million-token context window, enabling it to process large codebases and extended project contexts more effectively.
According to Z.ai, GLM-5.2 delivers significant improvements over its predecessor on coding benchmarks such as Terminal-Bench and SWE-bench Pro, while narrowing the gap with leading proprietary models.
The release also introduces configurable effort levels that allow users to balance performance, speed, and computational cost. Z.ai positions GLM-5.2 as a strong open-weight option for enterprise-scale development workflows and agentic coding applications.
