GPT-5.2 Pro continues to do the most impressive things on hard problems, but it does so with almost no visibility into what it is actually doing. The thinking trace is often unrelated to the final result, the tool use is unclear. No explainability, just remarkably good answers.

It is just a really smart model. Its worth running any high-stakes paper or analysis through the Oracle.

Please give GPT 5.2 Pro access to scholarly sources and let it actually quote things.
