OpenAI’s last upgrade to GPT-5 rollout faced backlash for retiring older models among users. OpenAI acknowledged that it underestimated users’ affection for the older GPTs, even if GPT-5 performs better in most ways.

In response to the critics, OpenAI’s CEO, Sam Altman, announced that rate limits for ChatGPT Plus users would be doubled and would continue to use the 4o model.

Previously, ChatGPT could tap into several different AI models, including GPT‑4o, o3, o4-mini, GPT‑4.1, and GPT‑4.5. But OpenAI has since replaced them with a family of GPT-5 models.

On Thursday, OpenAI unveiled a new flagship AI model, GPT-5, and began sharing the technology with ChatGPT users worldwide.

OpenAI executives called GPT-5 a “major upgrade” over their AI systems, saying the new technology was faster, more accurate, and less likely to hallucinate.

“GPT-5 is the first time that it feels like talking to an expert in any topic — a Ph.D.-level expert,” said OpenAI’s CEO, Sam Altman.

Also, it was the first time that OpenAI has used a reasoning model to power the free version of ChatGPT.

Experts agreed on the fact that the technology feels more human than previous models.

Sam Altman called the system a “significant step” along the path to the ultimate goal of the company and its rivals: artificial general intelligence, or AGI, a machine that can do anything the human brain can do.

GPT-5’s launch arrives in a moment when OpenAI, which is not yet profitable, plans to raise $40 billion this year, while being on pace to generate revenues of $20 billion by the end of 2025.
