Benchmark data for GPT-5.2 Pro and GPT-5.4 is coming soon on BenchLM.
BenchLM does not have sourced benchmark coverage for GPT-5.2 Pro yet. This comparison is currently limited to metadata such as context window, reasoning mode, and pricing where available.
GPT-5.2 Pro is priced at $25.00 input / $150.00 output per 1M tokens, versus $2.50 input / $15.00 output per 1M tokens for GPT-5.4. GPT-5.4 has the larger context window at 1.05M, compared with 400K for GPT-5.2 Pro.
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.
GPT-5.2 Pro: $25.00 input / $150.00 output per 1M tokens GPT-5.4: $2.50 input / $15.00 output per 1M tokens Both model pages still include creator, context window, reasoning mode, and other metadata while benchmark coverage fills in.
For engineers, researchers, and the plain curious — a weekly brief on new models, ranking shifts, and pricing changes.
