Both GPT 3.5 Turbo 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.
GPT 3.5 Turbo has a lower blended cost. GPT 3.5 Turbo: $0.50 input / $1.50 output. GLM 5.2: $0.78 input / $2.44 output.
GLM 5.2 has a larger context window: GPT 3.5 Turbo supports 16K tokens vs GLM 5.2 at 1M tokens.
Key differences: only GLM 5.2 offers extended reasoning mode. 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 GPT 3.5 Turbo and GLM 5.2 for free on idapt.app to see which performs better for your specific needs.
