OpenAI has unveiled GPT-5, its latest and most advanced AI model, now accessible to both free and paid ChatGPT users, as well as developers via API. The company stated that GPT-5 brings enhanced reasoning, speed, accuracy, and mathematical performance. During the launch event, CEO Sam Altman emphasized India’s increasing significance, noting, “India is our second-largest market after the U.S., and could soon become our biggest.” He praised the innovative ways Indians are using AI and confirmed that OpenAI is collaborating with local partners to boost AI affordability and accessibility in the country. Altman also announced plans to visit India in September.
GPT-5 is described as OpenAI’s most capable model for coding and complex tasks, offered in three variants—GPT-5, GPT-5-mini, and GPT-5-nano—giving developers flexibility between performance and cost. While GPT-5 serves as the primary reasoning model in the API, a lighter version called GPT-5-chat-latest is also available. Altman called GPT-5 a major leap over GPT-4, offering expert-level responses. It is available to free users for the first time. ChatGPT Team users already have access, with Enterprise and Edu users getting it next week. GPT-5 Pro offers deeper reasoning for Pro-tier users.
