GPT-5 is OpenAI’s latest, and now flagship, AI model. This new version is now the default system for a range of AI chatbots. OpenAI says GPT-5 is much more intelligent that the previous GPT-4 mode, with major improvements in complex front-end generation.

On a call with reporters Wednesday previewing the new chatbot, Altman likened GPT-5 to a Ph.D.-level expert. The new chatbot is also "the biggest single step forward" that OpenAI has taken in worldwide accessibility, Altman said.

OpenAI CEO Sam Altman has admitted that the launch of GPT-5, the company’s most advanced AI model to date, did not unfold as planned. Speaking to reporters, Altman acknowledged the wave of criticism that followed the rollout and explained what the company is doing to regain user trust.

OpenAI has released GPT-5, the latest version of the AI technology behind ChatGPT. This update is being closely watched to see if the frontier of generative AI is advancing or plateauing.

GPT-5 was touted as a major upgrade to ChatGPT, but not everyone thinks that’s the case: “Kill 4o isn’t innovation, it’s erasure.”

OpenAI’s new flagship AI model, GPT-5, crushes coding tests and complex logic, but lags behind rivals like Claude in creative work.

OpenAI says its latest version of the popular AI model is better at coding, more accurate and less deceptive than previous versions.

OpenAI’s latest upgrade was supposed to be a leap forward. Instead, it sparked backlash—and raises big questions about whether stitching together multiple models is the path to AI’s future.

While OpenAI’s GPT-5 is highly-performant, capable and an important step forward, it features just faint glimmers of true agentic AI.
