Both o4-mini and GLM 5.2 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 5.2 has a lower blended cost. o4-mini: $1.10 input / $4.40 output. GLM 5.2: $0.78 input / $2.44 output.
GLM 5.2 has a larger context window: o4-mini supports 200K tokens vs GLM 5.2 at 1M tokens.
o4-mini supports vision/image input, but GLM 5.2 does not.
Key differences: only o4-mini 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 o4-mini and GLM 5.2 for free on idapt.app to see which performs better for your specific needs.
