At long last, GPT-5 has arrived — and it’s free to all ChatGPT utilizers.
On Thursday, OpenAI launched what it describes as its smartest and quickest model yet during a livestream event. In a press briefing, OpenAI CEO Sam Altman detailed the foundation model’s capabilities. “GPT-3 sort of felt to me like talking to a high school student… GPT-4 felt like you’re kind of talking to a college student, GPT-5 is the first time that it really feels like talking to an expert in any topic,” stated Altman, who compared it to a “PhD level expert.”
OpenAI declares GPT-5 has improved expertise across coding, math, science, writing, and healthcare. Crucially, the company also claims the new large language model has a lower hallucination rate than o3, which was an unsettling 33 percent. But the key takeaway, Altman stated, is overall improvements in both obvious and subtle ways. “I tested going back to GPT-4, and it was quite miserable,” he stated.
GPT-5 will roll out today to ChatGPT free, Pro, and Plus utilizers, but is not yet available as of this writing. OpenAI declares free utilizers will have the strictest rate limits, and ChatGPT will fall back to a more lightweight model called GPT-5 mini after utilizers hit their limits. Pro utilizers will obtain higher rate limits, and Plus utilizers will have unlimited utilize and access to an even more powerful model called GPT-5 Pro. OpenAI also launched three model sizes for API utilizers: GPT-5, GPT-5 mini, and GPT-5 nano.
Let the testing launch.
This is a developing story, and we’ll update this post as new information becomes available…

GPT-5 also delivers a new utilizer experience, combining multiple tools into one and expanding access to OpenAI’s more advanced AI tools.
Users fatigued by the confapplying model picker will no longer required to manually select the right model for a tquestion. GPT-5 does away with that and combines reasoning capabilities from previous models into one unified experience. Head of ChatGPT Nick Turley underscored that this is the first time free utilizers will have access to reasoning, and “they don’t have to believe about it, becautilize GPT-5 just knows when to believe.”

“The vibes of this model are really good, and I believe that people are really going to feel that,” stated Turley, “especially average people who haven’t been spfinishing their time believeing about models.”
Speaking of vibes, OpenAI demoed a vibe-coding scenario where GPT-5 created a language-learning app with quizzes and games, all from a short natural language prompt. “[GPT-5] really puts the power of beautiful and effective coding in everyone’s hands,” stated Yann Dubois, a GPT-5 researcher.

GPT-5 arrives after years of anticipation and rumored setbacks. It’s been over two years since OpenAI launched GPT-4, the large language model that gave the already-popular ChatGPT a turbo boost in capabilities and fueled commercial adoption of AI models. But the GPT-5 launch has been repeatedly delayed amidst reports that the OpenAI team was struggling to achieve performance gains significant enough to warrant an entirely new model.
What GPT-5 means for the future of the AI indusattempt
ChatGPT is currently the most well-known AI chatbot, with 700 million weekly active utilizers, according to OpenAI. This means OpenAI has an outsized impact on the indusattempt as a whole. Mashable is just launchning to test GPT-5, and we’ll have more to share on its features and capabilities in the days and weeks ahead.
For now, it’s too early to declare if GPT-5 will silence AI critics, who declare agentic AI tools have failed to meet expectations. Some AI experts also believe that scaling laws — improving AI models through sheer data and computing power — is hitting a wall, suggesting the current path to AGI is longer than what OpenAI claims, if it’s even possible.
But Altman stated scaling laws “absolutely still hold” in the briefing. “We keep finding new dimensions to scale on, we can still scale the pre-training beautifully and obtain huge returns,” he stated. “Obviously, we have to invest in compute at like an-eye watering rate to obtain that, but we intfinish to keep doing it.”
Meanwhile, a troubling new issue has emerged where utilizers have experienced what’s described as “ChatGPT psychosis” and worsening existing mental health issues. A more advanced model raises questions about how utilizers will relate to it and OpenAI’s responsibility to mitigate harmful interactions.
“We take these issues extremely seriously,” stated Turley, who highlighted new features announced this week for healthier ChatGPT utilize. Turley stated OpenAI has been collaborating with mental health experts, creating improvements on issues like emotional reliance and ChatGPT sycophancy, and will have “a lot more to share soon.”
