This model is deprecated. We only continue performance benchmarking for the default 10k input token workload. Results for other workloads are historical and no longer updated.
Z AI has launched a newer model, GLM-5.1. We suggest considering it instead.
For more information, see comparison of GLM-5.1 to other models and API provider benchmarks for GLM-5.1.
