Both GLM 4.5 Air and Grok 4.6 are capable AI models. The best choice depends on your specific use case: consider pricing, context window, speed, and which capabilities (vision, reasoning, audio) you need.
GLM 4.5 Air has a lower blended cost. GLM 4.5 Air: $0.13 input / $0.85 output. Grok 4.6: $2.00 input / $6.00 output.
Grok 4.6 has a larger context window: GLM 4.5 Air supports 131K tokens vs Grok 4.6 at 500K tokens.
Grok 4.6 supports vision/image input, but GLM 4.5 Air does not.
Key differences: GLM 4.5 Air is significantly cheaper; only Grok 4.6 supports vision input. Compare full specs on this page.
If cost is your priority, choose the cheaper option. If you need the highest intelligence for complex tasks, pick the higher-scoring model. For long documents or codebases, choose the larger context window. You can try both GLM 4.5 Air and Grok 4.6 for free on idapt.app to see which performs better for your specific needs.
