Z.ai: GLM 4.5
Analysis Summary
Z.ai's GLM 4.5 is a mid-tier model with a 131K context window, tool use, and function calling. Its math benchmark is strong at 73.7, and GPQA at 0.782 is respectable, but the intelligence and coding indices both sit at 26, placing it well below frontier models. Agentic capability is modest at 32.5.
For businesses, GLM 4.5 suits lighter automation tasks, structured data extraction, and math-heavy workflows where cost matters. The lack of vision support limits its use in multimodal pipelines, and instruction-following scores are below average for client-facing content work.
At $0.60 input and $2.20 output, pricing is moderate but not exceptional given the capability level. Teams already embedded in Z.ai's ecosystem may find it useful for specific workloads, but most businesses will find stronger alternatives at similar or lower price points.

Editorial notes
GLM 4.5 from Z.ai delivers strong math performance and tool use with function calling at competitive pricing, but intelligence and coding indices sit in the limited range and provider adoption outside its home market is narrow.
