OpenAI has launched GPT-5, making it the default model across all tiers. GPT-5 is a unified system that intelligently routes queries to the most appropriate model based on complexity and user intent. It incorporates a fast model for straightforward questions and a deeper reasoning model for complex problems. If usage limits are reached, a 'mini' version handles remaining queries. GPT-5 in the API is available as regular, mini, and nano models, each with four reasoning levels.
GPT-5 demonstrates advancements in coding, writing, and health-related queries. It excels at front-end generation, debugging, and producing high-quality code from minimal prompting. The model can create compelling writing with literary depth and rhythm and provides more precise and reliable health answers. GPT-5 shows improved performance on academic benchmarks in maths, coding, and health.
GPT-5 is designed to be safer and more accurate, reducing hallucinations and improving instruction following. It also features 'safe-completions' to prevent disallowed content. Users can access GPT-5 through ChatGPT, with Plus subscribers receiving more usage and Pro subscribers gaining access to GPT-5 Pro for extended reasoning.
