GPT-5 Pushes Reasoning Benchmarks to New Heights Across STEM Disciplines

OpenAI has released detailed benchmark results for GPT-5, showing significant improvements on mathematical reasoning, scientific problem-solving, and multi-step logic tasks. The model achieves near-human performance on the GPQA Diamond dataset and sets a new record on MATH-500. Improvements are most pronounced on tasks requiring chaining multiple reasoning steps across different knowledge domains.
