OpenAI’s GPT 5: Vibe Coding Reaches New Heights

The wait is finally over. Today, right now, OpenAI is releasing its latest and greatest large language model, GPT-5, and making it available through the ChatGPT interface. According to OpenAI’s leaders, the model brings unprecedented powers of reasoning, brings vibe coding to a new level, is better than ever at agentic AI tasks, and comes with a raft of new safety features. “It’s a significant step along the path of AGI,” said OpenAI CEO Sam Altman at a press briefing yesterday, referring to the company’s goal of creating artificial general intelligence.

Altman called it a major upgrade from OpenAI’s prior models, saying that chatting with GPT-5 feels like talking to an expert with a Ph.D., no matter what topic you bring up. “Having this team of Ph.D.-level experts in your pocket, available all the time, to do whatever you need, is pretty cool,” he said.

Nick Turley, head of ChatGPT, said he thinks the most remarkable thing about the model is that “it just feels more human. So when you’re talking to this thing, it feels just a little bit more natural.”

Who Has Access to GPT-5?

The new model is available to everyone via ChatGPT, including users of the free version. Paying users do get certain perks, like access to a more powerful version of the model.

The introduction of GPT-5 cuts through the confusion over OpenAI’s many large language models (LLMs) with different names and capabilities. Since November 2022, when ChatGPT debuted based on the GPT-3.5 model, the public has tried to keep up as OpenAI launched GPT-4, GPT-4o, GPT-4.5, and the “reasoning” models o1 and o3. The reasoning models use a technique called chain-of-thought, in which they work through a problem step-by-step to better answer difficult and sophisticated questions.

But people using the free version of ChatGPT haven’t had access to those top reasoning models. “This is, for most people on ChatGPT, the first real introduction to reasoning,” said Turley, adding that they don’t have to select anything to turn on reasoning capacity for harder queries. “They don’t even have to think about it because GPT-5 just knows when to think.”

How GPT-5 Performs

We’ll know more about GPT-5’s performance when OpenAI releases its system card today, which should contain information about how well it did on various benchmarks. For now, we’re going on statements from its proud creators and a brief demo conducted during the press briefing.

As for those proud statements: The OpenAI team claims that GPT-5 is not only smarter and faster, it’s also more trustworthy. They say that it has fewer hallucinations (in other words, it doesn’t make up random stuff as often), and that it’s less likely to confidently put forth a wrong answer, instead being more likely to admit the limits of its own knowledge.
