OpenAI Launches GPT-5 – Major Leap in AI with Smarter, Faster and More Natural Chat Experience

Highlights

• GPT-5 introduces major upgrades in reasoning, speed and contextual understanding, making conversations feel expert-level and intuitive.
• It features a smart router that dynamically switches between models based on query complexity, with reduced hallucinations and improved accuracy.
• GPT-5 is now available across all ChatGPT plans including free users.
• It offers new personality presets like Cynic, Robot, Listener and Nerd.

OpenAI has officially introduced GPT-5, its next-generation artificial intelligence model, in a livestreamed event. This latest release marks a major advancement in the company’s AI journey, reinforcing its push to stay at the forefront of global AI innovation.

Introducing GPT-5, OpenAI said, “Today we’re introducing GPT‑5⁠, OpenAI’s smartest, fastest, most useful model yet, and a major step towards placing intelligence at the center of every business. GPT‑5 unites and exceeds OpenAI’s prior breakthroughs in frontier intelligence, spanning 4o, OpenAI o-series reasoning, agents, and advanced math⁠(opens in a new window) capabilities. […] GPT‑5 delivers leaps in accuracy, speed, reasoning, context recognition, structured thinking, and problem-solving. The true magic will happen when businesses start applying GPT‑5 to imagine new use cases.”

Described as a significant upgrade in terms of creative writing, complex reasoning, and computer programming, GPT-5 aims to elevate the ChatGPT experience. “For the first time,” said OpenAI CEO Sam Altman, “it really feels like talking to an expert in any topic.”

“GPT‑5 is a unified system with a smart, efficient model that answers most questions, a deeper reasoning model (GPT‑5 thinking) for harder problems, and a real‑time router that quickly decides which to use based on conversation type, complexity, tool needs, and your explicit intent (for example, if you say “think hard about this” in the prompt). The router is continuously trained on real signals, including when users switch models, preference rates for responses, and measured correctness, improving over time. Once usage limits are reached, a mini version of each model handles remaining queries. In the near future, we plan to integrate these capabilities into a single model,” OpenAI further added.

OpenAI, which introduced ChatGPT nearly three years ago using GPT-3.5, has steadily evolved its models to support a wide range of use cases, including reasoning, coding, and autonomous agent workflows.

New Personalities and Smarter Processing

To enhance user interaction, OpenAI has introduced four experimental personality presets in ChatGPT – Cynic, Robot, Listener, and Nerd. These are available as part of a research preview.

GPT-5 also includes a new capability that allows it to autonomously determine how deeply it should process a user’s query, eliminating the need for manual toggling between simple and complex modes. This is expected to improve both performance and efficiency by optimising server load.

Altman Says GPT-5 Made Him Feel ‘Useless’

The debut of GPT-5 has been highly anticipated, especially after Altman hinted earlier this year that the model would exceed expectations. During a recent podcast, he shared a personal anecdote about GPT-5’s intelligence.

“I got emailed a question that I didn’t quite understand and I put it in the model — this is GPT-5 — and it answered it perfectly,” he said. “I felt useless relative to the AI.”

Nick Turley, who leads the ChatGPT team at OpenAI, emphasised that GPT-5 not only responds faster but also delivers more accurate results. “When you’re talking to this thing, it feels just a little bit more natural,” he noted.

GPT-5 Availability

GPT-5 is now accessible to users across all ChatGPT plans, which includes Team, Pro, Plus, and even the free tier. Free users will initially access GPT-5 but will switch to GPT-5 mini after reaching usage limits.

Enterprise and Education customers will gain access next week. OpenAI also plans to release GPT-5 Pro soon, which it describes as “a version with extended reasoning for even more reliable and detailed answers,” available to Team, Enterprise, and Edu users.

Developers using the OpenAI API will have access to GPT-5, GPT-5 mini, and GPT-5 nano models.
