San Francisco: OpenAI has announced the official launch of GPT-5, its most advanced large-scale artificial intelligence model to date.
The company says GPT-5 is significantly smarter, faster, and more useful, with marked improvements in areas like writing, software development, and healthcare assistance. OpenAI CEO Sam Altman said that, “I tried going back to GPT-4, and it was quite miserable.”
Since the debut of ChatGPT in 2022, OpenAI has rapidly become one of the most influential tech companies in the AI space. One of the most notable upgrades in GPT-5 is its reduced hallucination rate, meaning the model fabricates fewer responses. OpenAI says it has spent 5,000 hours testing the model with a focus on safety.
Rather than refusing to answer risky prompts outright, GPT-5 employs high-level, constrained responses that ensure utility without compromising safety. “The model is now able to recognize when a task cannot be completed, avoid speculation, and clearly explain its limitations,” said Michelle Pokrass, post-training lead at OpenAI.

In a live demonstration, OpenAI showed off GPT-5’s ability to perform vibe coding, where users generate fully functional software with a simple written prompt.
GPT-5 is being rolled out to Free, Plus, Pro, and Team users of ChatGPT. Notably, this marks the first time Free-tier users will have access to a reasoning model, capable of step-by-step internal thought before producing a response. Once Free users hit their usage cap, they’ll transition to GPT-5 mini, a lighter version.
Plus users receive higher usage limits, Pro users enjoy unlimited access to GPT-5 and its premium variant GPT-5 Pro, and enterprise-level access for ChatGPT Edu and ChatGPT Enterprise users is expected within a week. OpenAI is also releasing three developer versions via API — GPT-5, GPT-5 Mini, and GPT-5 Nano, designed to balance cost, latency, and performance across different use cases.
Today, GPT-5 launches across our platforms, including Microsoft 365 Copilot, Copilot, GitHub Copilot, and Azure AI Foundry.
It’s the most capable model yet from our partners at OpenAI, bringing powerful new advances in reasoning, coding, and chat, all trained on Azure.
It’s…

Microsoft, a major partner and investor in OpenAI, is integrating GPT-5 into its products swiftly. According to a blog post, Microsoft 365 Copilot, Copilot for consumers, and Azure AI Foundry will soon be powered by GPT-5. GPT-5’s design focuses not just on functionality but also on natural interaction. The model is said to feel more human and intuitive than any of its predecessors.
“It’s like having a team of Ph.D.-level experts on hand at any time. People are limited by ideas, but not the ability to execute, in many new ways,” said Altman.
OpenAI also released two open-weight language models earlier this week for the first time since GPT-2 in 2019, aimed at developers looking for more affordable, customizable solutions.
