glm-4.5-xThe GLM-4.5 series is built for agent-style AI, combining reasoning, coding, and tool use. GLM-4.5 has 355B total parameters (32B active), while GLM-4.5-Air is a lighter 106B/12B version. Both support hybrid modes — a “thinking” mode for complex reasoning and tools, and a fast non-thinking mode for quick replies. The models are open-sourced (including FP8 versions) under the MIT license for commercial use, and they rank highly on benchmarks: GLM-4.5 scores 63.2 (3rd overall), while GLM-4.5-Air achieves 59.8 with better efficiency.
