Notable features
- GPT-5 was launched on August 7, 2025 as a unified system: a smart, efficient model, a deeper reasoning model (GPT-5 thinking) and a real-time router that chooses between them; a mini version handles queries once limits are reached[1][4]
- In the API it has a 400,000-token context window and 128,000 max output tokens, takes text and image input with text output, supports reasoning effort from minimal to high, has a September 30, 2024 knowledge cutoff, and costs $1.25 per million input tokens ($0.125 cached) and $10 per million output tokens[3]
- Benchmarks: 94.6% AIME 2025 (no tools), 74.9% SWE-bench Verified, 88% Aider Polyglot, 84.2% MMMU, 46.2% HealthBench Hard[4]
- GPT-5 thinking beats o3 with 50-80% fewer output tokens; about 45% fewer factual errors than GPT-4o with web search[4]
- Sycophancy cut from 14.5% to under 6% on targeted evals; new "safe completions" safety training; treated as High capability in biological and chemical domain[4]
