Frequently Asked Questions (3)
Can I compare GPT-5.2 and GPT-5.2 Pro 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 GPT-5.2 and GPT-5.2 Pro today?
GPT-5.2: $1.75 input / $14.00 output per 1M tokens GPT-5.2 Pro: $25.00 input / $150.00 output per 1M tokens Both model pages still include creator, context window, reasoning mode, and other metadata while benchmark coverage fills in.
