Z.AI: GLM 4.5

Z.AI's GLM-4.5, a flagship foundation model designed for agent-based applications, exhibits exceptional reliability with a 99% success rate, indicating minimal technical failures. However, it tends to have longer response times, ranking in the 10th percentile for speed, and is positioned at premium pricing levels, ranking in the 18th percentile for cost. Despite its slower speed and higher price point, GLM-4.5 demonstrates strong performance across several critical benchmarks. It achieves perfect accuracy in General Knowledge, making it the most accurate model at its price point and among models of comparable speed. The model also excels in Instruction Following (85th percentile), Coding (82nd percentile), Reasoning (81st percentile), and Mathematics (87th percentile), showcasing its robust capabilities in complex problem-solving and logical tasks. While its Hallucinations accuracy is moderate at 94.0% (46th percentile), it performs well in Ethics (99.0% accuracy). A notable weakness is its Email Classification accuracy, which is 93.0% but ranks in the 23rd percentile, suggesting room for improvement in this specific domain compared to other models. Its hybrid inference mode, with "thinking" and "non-thinking" options, offers flexibility for diverse application needs.
