GPT-5
OpenAI's latest flagship model. Major leap in reasoning, coding, and instruction following over GPT-4o. Powers ChatGPT Plus/Pro and the API. Available via API and ChatGPT.
GPT-5 is OpenAI's most capable model, representing a significant jump in reasoning, coding, math, and long-context performance over GPT-4o. It unifies the capabilities that were previously split across separate models (GPT-4o for speed, o3 for reasoning) into a single model that adaptively allocates compute based on task difficulty. Available through the OpenAI API and ChatGPT (Plus, Pro, and Team plans). GPT-5 excels at complex multi-step tasks, code generation, and nuanced instruction following. The codex-mini variant powers OpenAI Codex for autonomous coding. For developers building on the OpenAI ecosystem, GPT-5 is the new default for production applications.
