Analysis Summary

GLM 4.5 from Z.ai is a capable model with verified benchmark data showing strong coding performance: a livecodebench score of 0.738 places it competitively, and its agentic index of 32.5 supports multi-step tool-use workflows. GPQA at 0.782 and MMLU Pro at 0.835 confirm solid general reasoning depth.

For businesses, GLM 4.5 is well-suited to coding pipelines, agentic automation, and structured content tasks. Long-context reasoning (lcr 0.48) and instruction following (ifbench 0.44) are above average, making it viable for document-heavy workflows. The 131K context window is adequate for most business use cases.

At $0.60 input and $2.20 output, pricing is moderate. The -4 point regional accessibility adjustment applies given provider availability considerations. Teams prioritising coding and agentic capability at a reasonable price point will find GLM 4.5 a strong performer, though businesses should verify API availability in their region before committing.
