Benchmark data for GPT-5.4 Pro and o3-pro is coming soon on BenchLM.
BenchLM does not have sourced benchmark coverage for o3-pro yet. This comparison is currently limited to metadata such as context window, reasoning mode, and pricing where available.
GPT-5.4 Pro is priced at $30.00 input / $180.00 output per 1M tokens, versus $20.00 input / $80.00 output per 1M tokens for o3-pro. GPT-5.4 Pro has the larger context window at 1.05M, compared with 200K for o3-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-5.4 Pro: $30.00 input / $180.00 output per 1M tokens o3-pro: $20.00 input / $80.00 output per 1M tokens Both model pages still include creator, context window, reasoning mode, and other metadata while benchmark coverage fills in.
