GLM 5.2

GLM-5.2 is Zhipu AI’s latest flagship model, designed to handle extended, complex workflows with strong bilingual reasoning (Chinese and English) and deep agent integration. It introduces a reliable 1M-token context window, enabling consistent performance across long-running tasks such as large-scale coding, research, and multi-step automation. The model improves coding flexibility by supporting adjustable reasoning effort, allowing developers to balance speed and depth depending on the task. Its upgraded architecture, including innovations like IndexShare and enhanced speculative decoding, reduces computational overhead while improving throughput and stability in long sequences. GLM-5.2 is optimized for real-world engineering scenarios, maintaining accuracy across long, complex workflows such as debugging, system design, and performance optimization. It is well-suited for building advanced AI agents that require sustained reasoning, tool use, and reliable execution over extended interactions.
