GPT-5: An AI That Chooses to Think — Fast, Deep, and More Trustworthy.
OpenAI unveiled GPT-5 on August 7, 2025: a unified system that routes between a fast model and a deeper “thinking” model in real time. GPT-5 shows measurable gains across coding, math, creative writing, health, and multimodal perception; its “GPT-5 thinking” mode delivers more accurate and more honest responses on complex tasks. The family includes three flavors (regular, mini, nano), supports very large input/output token windows, and exposes API options for reasoning traces and effort levels. Pricing is positioned competitively relative to peers, with notable token-caching discounts for recent conversation history. Despite progress in hallucination reduction and deception metrics, prompt-injection and safety remain active concerns, addressed by new techniques such as “safe-completions.”
