What is GPT-5?

GPT-5 is OpenAI's flagship frontier model, delivering state-of-the-art performance across reasoning, coding, math, and creative tasks. It builds on GPT-4o's multimodal foundations with significantly improved reasoning depth and instruction-following.

Our Review

GPT-5 represents a significant capability leap over GPT-4o, particularly in multi-step reasoning and complex instruction following. For teams building production AI agents, it's the most reliable choice for tasks requiring deep reasoning. The price premium is justified when output quality is critical.
