GPT 5
GPT-5 is one of OpenAI's most advanced models, optimized for complex tasks that require step-by-step reasoning, instruction following, and accuracy in high-stakes use cases. It delivers major gains in code quality and reasoning, with reduced hallucination and sycophancy and strong performance on coding, writing, and health-related tasks.
