OpenAI announced on 26 October 2026 that its proprietary large language model had generated three major mathematical proofs. [^1]

Researchers using an OpenAI model discovered two major vulnerabilities in PHP during the week prior to publication. [^2]

It is not confirmed in the filed reports that the same model instance was used for both tasks.
