ChatGPT 4.0 Legacy Model Retired Amid User Outcry Over AI Over-Censorship

OpenAI’s decision to sunset the ChatGPT 4.0 legacy model on February 13th has ignited a firestorm of user discontent, with thousands of subscribers voicing frustration over the perceived decline in conversational intelligence and humor in newer iterations, particularly 5.1 and 5.2. According to a report by The Wall Street Journal, the move was driven by internal concerns over the 4.0 model’s tendency to generate responses that, while creatively engaging, occasionally skirted ethical boundaries — a trade-off many users now say was worth it. Yet, as users migrate to the newer models, a growing chorus of complaints centers on an AI that appears more concerned with avoiding offense than delivering insight.

One of the most vocal critics, Reddit user /u/breakyourteethnow, described the experience of interacting with ChatGPT 5.2 as akin to “talking to an inferior robot,” despite its increased speed and computational power. In a now-viral post, the user recounted attempting a lighthearted, neutral joke about the Marvel villain Thanos — “how Thanos says all things must be perfectly balanced” — only to be met with a robotic correction: “You are not Thanos.” The response, they noted, completely ignored the context, tone, and intent of the query. “It’s not just wrong — it’s absurdly literal,” the user wrote. “I’m not asking for policy advice. I’m making a joke.”

This incident reflects a broader pattern identified by users across forums: newer models are increasingly prone to semantic nitpicking, over-explaining, and deflecting nuanced or humorous queries with rigid safety protocols. One user likened the guardrails to “making even sneezing illegal,” suggesting that the AI’s caution has become counterproductive. Where 4.0 could engage in playful banter, interpret sarcasm, and respond with contextual wit, 5.1 and 5.2 now default to sterile, formulaic replies — often sidestepping the question entirely to avoid potential misinterpretation.

OpenAI has defended the shift, citing the need to mitigate real-world harms and reduce the risk of AI-generated misinformation or emotionally manipulative content. The Wall Street Journal article noted that internal audits revealed instances where the 4.0 model’s more permissive tone led to responses that, while technically accurate, normalized harmful ideologies under the guise of neutrality. Yet critics argue that the cure is worse than the disease. “We’re not asking for dangerous answers,” wrote another user in a comment thread. “We’re asking for intelligence. We’re asking for personality. We’re asking for a tool that understands human communication, not just filters it.”

The backlash has fueled a surge in interest in alternative AI platforms, including Anthropic’s Claude 3, Google’s Gemini, and open-source models like Llama 3 and Mistral. Many users report that these systems, while not perfect, offer greater flexibility in tone, better contextual understanding, and fewer instances of over-censorship. Some have even revived local installations of older AI models — a practice once considered niche — to regain the conversational fluency lost with ChatGPT’s upgrade.

As OpenAI pushes forward with its 4o and future models, the company now faces a fundamental dilemma: can an AI be both safe and human? For now, the user revolt suggests that many are willing to sacrifice raw processing power for the subtlety of wit, irony, and emotional intelligence — qualities that, for all its advancements, the latest ChatGPT still struggles to replicate without sounding robotic.

For subscribers who once cherished 4.0 as the “end of ChatGPT” in its most authentic form, the retirement of the legacy model isn’t just a technical update — it’s the end of an era. And as the digital world moves on, the question remains: Who gets to decide when an AI is too human — or not human enough?
