Z.ai: GLM 5
Z.ai: GLM 5 is designed to handle text inputs within an expansive context length of 204800 tokens and supports both reasoning and tool integration, making it suitable for complex tasks that require multiple steps or external data access.

Given its blended benchmark score of 76.2 across two independent benchmarks, Z.ai: GLM 5 demonstrates solid performance in both AI indexing and EQbench. At a pricing point of $0.95 per million input tokens and $2.55 per million output tokens, it offers a competitive price for businesses requiring robust text processing capabilities. While its benchmark coverage is moderate at two independent benchmarks, this model could be a strong contender for those prioritizing cost-effectiveness in their AI solution.
