Z.ai: GLM 4.6
Analysis Summary
GLM 4.6 from Z.ai is a capable model with an intelligence index of 32.5 and a standout agentic index of 47.7, placing it among the stronger agentic models in its price tier. The livecodebench score of 0.695 and coding index of 29.5 show solid coding capability. Tool use and function calling are supported, and the 202K context window handles long documents well.
The absence of vision limits it to text-only pipelines. At $0.43 input and $1.74 output per million tokens, pricing is reasonable for its agentic and coding capability. It suits multi-step automation, structured data workflows, and coding assistance where vision is not required.
A -4 regional accessibility adjustment applies. For teams already integrated with Z.ai's platform, GLM 4.6 is a strong agentic and coding option; for businesses prioritising Western provider support, Claude Sonnet 4.5 offers significantly stronger benchmarks at a higher price point.
