The end of an AI that shocked the world: OpenAI retires GPT-4

A look back at GPT-4’s legacy as OpenAI pulls the pioneering 2023 AI model from ChatGPT.

One of the most influential—and by some counts, notorious—AI models yet released will soon fade into history. OpenAI announced on April 10 that GPT-4 will be "fully replaced" by GPT-4o in ChatGPT at the end of April, bringing a public-facing end to the model that accelerated a global AI race when it launched in March 2023.

"Effective April 30, 2025, GPT-4 will be retired from ChatGPT and fully replaced by GPT-4o," OpenAI wrote in its April 10 changelog for ChatGPT. While ChatGPT users will no longer be able to chat with the older AI model, the company added that "GPT-4 will still be available in the API," providing some reassurance to developers who might still be using the older model for various tasks.

The retirement marks the end of an era that began on March 14, 2023, when GPT-4 demonstrated capabilities that shocked some observers: reportedly scoring at the 90th percentile on the Uniform Bar Exam, acing AP tests, and solving complex reasoning problems that stumped previous models. Its release created a wave of immense hype—and existential panic—about AI's ability to imitate human communication and composition.

Redditor accidentally reinvents discarded ’90s tool to escape today’s age gates

The ’90s called. They want their flawed age verification methods back.

Back in the mid-1990s, when The Net was among the top box office draws and Americans were just starting to flock online in droves, kids had to swipe their parents' credit cards or find a fraudulent number online to access adult content on the web. But today's kids—even in states with the strictest age verification laws—know they can just use Google.

Last month, a study analyzing the relative popularity of Google search terms found that age verification laws shift users' search behavior. It's impossible to tell if the shift represents young users attempting to circumvent the child-focused law or adult users who aren't the actual target of the laws. But overall, enforcement causes nearly half of users to stop searching for popular adult sites complying with laws and instead search for a noncompliant rival (48 percent) or virtual private network (VPN) services (34 percent), which are used to mask a location and circumvent age checks on preferred sites, the study found.

"Individuals adapt primarily by moving to content providers that do not require age verification," the study concluded.
