While discussing the capabilities of GPT-4.5, it is essential to compare it with its predecessors. In benchmarks like SIMPLE QA—which assesses straightforward question-answering—GPT-4.5 demonstrates substantial improvement over prior models like GPT-4 and earlier versions.

Recent evaluations indicate that human testers rated GPT-4.5 favorably across various dimensions, including accuracy and factuality, especially in contexts requiring emotional nuance.
