GLM-4.6
Overview
GLM-4.6 is an open-source language model developed by Z.ai, released in September 2025. It features a Mixture-of-Experts (MoE) architecture with a total of 357 billion parameters, of which 32 billion are active during inference. The model offers a context window of approximately 200,000 tokens, enabling it to process extensive text inputs effectively. This design allows GLM-4.6 to handle complex tasks such as coding, reasoning, and agentic orchestration, making it suitable for applications requiring long-context understanding and sophisticated problem-solving capabilities. In terms of performance, GLM-4.6 has demonstrated competitive results across various benchmarks. Notably, it achieved a score of 82.9 on the GPQA-Diamond benchmark, which evaluates the model's proficiency in answering graduate-level physics, chemistry, and biology questions. Additionally, it scored 70.1 on LiveCodeBench, a coding benchmark that assesses the model's ability to solve programming problems. These results position GLM-4.6 as a strong contender in the open-source language model landscape, particularly for tasks demanding extensive context processing and advanced reasoning abilities. GLM-4.6 is released under the MIT license, permitting commercial use and modification. It is available through Z.ai's platform, offering API access for integration into various applications. The model's open-source nature and robust performance make it a valuable resource for enterprises and developers seeking customizable solutions for complex language processing tasks.
