GLM Comparisons

Head-to-head comparisons between GLM and the other models developers shortlist. Each comparison opens with a clear answer, then backs it up with side-by-side prices from the official pricing pages, context windows and output limits, open-weights status, feature support such as vision, thinking modes, JSON output and tool calling, and the benchmark results each vendor has published, clearly attributed. You also get our own test results from the five-task battery we run in GLM Chat, so you can see how the models handle real coding, writing and extraction prompts. Every comparison ends with a practical "pick this if" section so you can decide in a minute. Start with GLM vs DeepSeek for the best-value open models, or GLM vs Claude if you are weighing cost against the strongest closed coding models, and use the free chat to try your own prompts on each GLM model.
