OpenAI has officially rolled out GPT-5, the newest version of its AI model, now available to free and paid ChatGPT users, along with developers via API access. The company says this upgrade boosts reasoning, speed, accuracy, and mathematical skills.

At the launch event, OpenAI CEO Sam Altman put a spotlight on India’s growing role in the AI space. “India is our second-largest market in the world after the US, and it may well become our largest,” he said. “What users are doing with AI in India is quite remarkable.” Altman also revealed that OpenAI is working with local partners to make AI tools more affordable and accessible in the country and confirmed he will be visiting India in September.

The company describes GPT-5 as its most advanced model yet for coding and agentic tasks. It’s being released in three versions—GPT-5, GPT-5-mini, and GPT-5-nano—giving developers flexibility to balance performance with cost. Within the API, GPT-5 serves as the primary reasoning model, while a lighter, non-reasoning option called GPT-5-chat-latest is also available.

Altman emphasised the leap from GPT-4 to GPT-5 in delivering expert-level responses. “This is the first time one of our mainline models feels like talking to a PhD-level expert,” he noted. “We wanted to make it available in our free tier for the first time.”

ChatGPT Team users already have access to GPT-5, with Enterprise and Edu customers set to receive it next week. The company is also preparing to launch GPT-5 Pro—an extended reasoning variant—for these customers soon.
