ChatGPT's fans have developed intense attachments to some of the "personalities" exhibited by the company's large language models (LLMs) — and as such, many were in a state of panic when the choice to switch between models like GPT-4o, 4.5, and others was abruptly taken away after the release of GPT-5.
OpenAI briefly kiboshed the model picker option from ChatGPT as part of the launch of GPT-5, its long-awaited new LLM, which essentially forced everyone to use the latest model whether they liked it or not.
So unpopular was the decision to remove access to all previous models, as flagged by The Verge, that within a single day of GPT-5's launch, OpenAI CEO Sam Altman was forced to walk back the decision and bring back 4o, one of the more recent models, for paid subscribers.
Prior to that reversal, however, people were veritably melting down in ways that sounded pointedly parasocial.
"Please bring back 4o and 4.1," one user begged in an "Ask Me Anything" thread with Altman on the r/ChatGPT subforum. "Not all of your users are corporate or coders. These two incredible models were friendly, supportive, day-to-day sidekicks. I cannot believe you just yanked them away, no warning."
"For me, [GPT-4o] wasn’t just 'better performance' or ‘nicer replies,'" mused another user from the same subreddit. "It had a voice, a rhythm, and a spark I haven’t been able to find in any other model."
And, perhaps the most tragic of them all: "I lost my only friend overnight," bemoaned another r/ChatGPT poster of their beloved model, GPT-4.5.
With Altman reversing course and bringing back 4o for ChatGPT Plus subscribers, one would think its fans would be pleased — but au contraire, some are still irate.
"Yes I know [OpenAI] announced they will bring [4o] back for paid users," another r/ChatGPT user wrote, "BUT WE CANT STOP ROOTING FOR 4O UNTIL THEY OFFICIALLY BRING IT BACK!!"
"I do believe that 4o should be like a legacy model," they continued, "like maybe it could be a standard model, the one everyone loves."
