OpenAI Launches GPT-5 With New Model Variants

The release introduces multiple model variants—GPT-5, Pro, Mini, and Nano—each designed for various speeds, costs, and computational requirements, with an automatic system directing user queries to the best option. GPT-5 offers improved reasoning, coding, and creative writing abilities, with faster, more accurate responses and reduced hallucination rates. Users benefit from customizable chatbot personalities, and GPT-5's capabilities extend to generating software on demand and tackling complex, multi-step tasks. The model's reach is expanding through new partnerships with enterprise and government clients.
