Benchmark data for GLM-4.5 and GPT-5.1 is coming soon on BenchLM.
BenchLM does not have sourced benchmark coverage for GLM-4.5 yet. This comparison is currently limited to metadata such as context window, reasoning mode, and pricing where available.
GPT-5.1 is priced at $1.25 input / $10.00 output per 1M tokens, versus $0.60 input / $2.20 output per 1M tokens for GLM-4.5. GPT-5.1 has the larger context window at 200K, compared with 128K for GLM-4.5.
Not fully yet. BenchLM is tracking both models, but the sourced benchmark breakdown for this comparison is still coming soon.
BenchLM only shows category winners and benchmark-level calls when we have sourced results that can be compared fairly. For these models, the public benchmark coverage is not complete enough yet.
GLM-4.5: $0.60 input / $2.20 output per 1M tokens GPT-5.1: $1.25 input / $10.00 output per 1M tokens Both model pages still include creator, context window, reasoning mode, and other metadata while benchmark coverage fills in.
