OpenAI Unleashes GPT-5 and Microsoft Adopts It Immediately

OpenAI today announced GPT-5, its latest and most powerful family of AI large language models (LLMs), and Microsoft is immediately on board, stating that it is already incorporating GPT-5 across its consumer, developer, and enterprise offerings.

“GPT-5 really feels like talking to an expert in any topic, like a PhD-level expert,” OpenAI CEO Sam Altman told the press ahead of today’s live stream unveiling. “It feels significantly better in obvious ways and in subtle ways.”

The GPT-5 models are all reasoning models, so they appear to think through the problems they are solving in real-time rather than generate responses more quickly using pattern matching. It’s also a so-called integrated model, so users won’t need to manually choose a model as before. That said, you can also instruct it to “think harder” or “think more precisely” in prompts.

OpenAI notes that GPT-5 has an enhanced voice mode with smarter and more natural voices, different personalities, improved memory, and better connectivity with third-party services like Gmail and Google Calendar. It’s also OpenAI’s best coding model yet, has multi-agent capabilities, and is much more reliable than previous models, especially with health information.

The integrated GPT-5 models are already rolling out to all ChatGPT users, including free, Plus, and Pro subscribers. It appears that there will also be a new tier between free and Plus called ChatGPT Go that provides more messages, file uploads, image generation, and advanced data analysis than the fee version.

As for Microsoft, it says that its enterprise and consumer customers will automatically get the benefits of GPT-5 without having to do anything. Developers using GitHub Copilot will get GPT-5 for coding and agentic tasks, and the new GPT-5 models are being made available in Azure AI Foundry. And Microsoft’s AI Red team evaluated GPT-5 and found that it has “one of the strongest AI safety profiles among prior OpenAI models against several modes of attack, including malware generation, fraud/scam automation, and other harms.”

Microsoft notes that anyone can try GPT-5 with Microsoft Copilot for free on the web, or by using the Copilot app on Windows, Mac, Android, iPhone, and iPad.

Ahead of today’s launch, we suffered through several leaks and rumors about GPT-5, and today got off to a weird start when Microsoft’s GitHub inadvertently leaked that the GPT-5 family would include four models with “major improvements in reasoning, code quality, and user experience.” Then Sam Altman tweeted an image of the Death Star from “Star Wars: Return of the Jedi” without explanation, though he soon tweeted about today’s livestream reveal as well.
