OpenAI has officially launched GPT-5, its most advanced AI model to date. In a pre-briefing, Sam Altman shared that once he tried GPT-5 he had a hard time going back to GPT-4, likening the revert to using an old iPhone.
Designed to be more useful, more accurate and more human than any version before it, this is by far OpenAI’s smartest and most efficient model.
GPT-5 is now rolling out in ChatGPT and the API, with the company describing it as a “unified system” built to deliver the best possible answer every time; no model switching required. This marks a major shift from the current GPT-4/4o experience and introduces a more seamless way to interact with AI.
Smarter, safer and more proactive
OpenAI says GPT-5 brings noticeable improvements in reasoning, accuracy and reliability.
It hallucinates less, adapts better to your context and introduces a new feature called “safe completion.” In other words, the model won’t blindly comply with risky prompts or flatly refuse either. Instead, it aims to give the most helpful response within safety boundaries, offering clear reasoning when it can’t help.
A major leap in coding and workflows
GPT-5 is OpenAI’s strongest coding model ever. It can create entire websites, apps, and games, even for users who don’t know how to code.
Developers can expect smarter debugging, cleaner frontend design and more agentic behavior, with tools like free-form function calling, verbosity control and reasoning effort toggles.
For non-technical users and casual users, GPT-5 also enhances writing workflows, supports health-related questions with improved contextual understanding and is more proactive in helping users weigh options or understand complex information.
OpenAI notes that it doesn’t replace medical professionals, but it’s now better equipped to support health-related discussions.
New customization and voice upgrades
ChatGPT now lets users customize the look and tone of their experience. You can change chat colors and choose from new preset personalities like “Cynic,” “Listener” or “Robot.”
Voice interactions have also improved with adaptive tone control and higher usage limits for paid users.
OpenAI is unifying all users under this new voice mode and retiring the previous “Standard Voice” within 30 days.
Connect Gmail, Google Calendar and more
Another standout feature is Google integration. Users will soon be able to connect Gmail, Calendar and Contacts directly to ChatGPT.
Once enabled, the assistant will intelligently know when to reference your data, without having to be explicitly told.
Available now and free for all users
GPT-5 is rolling out starting today to all ChatGPT users and is available for everyone for free.
Free users will get access to GPT-5 and GPT-5 mini, though usage is capped. Plus and Pro users will see significantly higher usage limits, with unlimited access available to Pro subscribers.
GPT-5 will also be the default model for enterprise and EDU accounts next week.
On the developer side, GPT-5 is launching with three model variants, gpt-5, gpt-5-mini, and gpt-5-nano, with improved latency and cost options. Pricing is more affordable than GPT-4o, with caching discounts built in.
Final thoughts
With GPT-5, OpenAI is redefining what AI can be in everyday life. Whether you’re building software, writing reports, managing a schedule, or just trying to get a clearer answer to a complex question, GPT-5 promises to take it all in one with ease and accuracy.
