Benchmark data for GLM-5 (Reasoning) and GPT-4.1 mini is coming soon on BenchLM.
Confidence note. This is a partial-evidence comparison with 1 shared benchmark result across 1 evidence category; 0 of 8 categories currently have scoreable aggregates for both models. Treat the verdict as directional until coverage is more balanced.
Why this result
BenchLM has partial data for these models, but not enough overlapping benchmark coverage to produce a fair score-level comparison yet.
GLM-5 (Reasoning) is priced at $1.00 input / $3.20 output per 1M tokens, versus $0.40 input / $1.60 output per 1M tokens for GPT-4.1 mini. GPT-4.1 mini has the larger context window at 1M, compared with 200K for GLM-5 (Reasoning).

Frequently Asked Questions (3)
Can I compare GLM-5 (Reasoning) and GPT-4.1 mini on BenchLM yet?
Not fully yet. BenchLM is tracking both models, but the sourced benchmark breakdown for this comparison is still coming soon.
Why does this comparison show “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.
What data is available for GLM-5 (Reasoning) and GPT-4.1 mini today?
GLM-5 (Reasoning): $1.00 input / $3.20 output per 1M tokens GPT-4.1 mini: $0.40 input / $1.60 output per 1M tokens Both model pages still include creator, context window, reasoning mode, and other metadata while benchmark coverage fills in.
