Users Report Drastic Decline in GPT-4o Performance, Overly Cautionary Responses Spark Outcry

Since the rollout of OpenAI’s latest model iteration, users across multiple platforms have reported a sharp decline in the AI’s utility, particularly in domains requiring practical, factual, or comparative recommendations. According to a widely shared post on Reddit’s r/OpenAI forum, the current version of GPT appears to be excessively risk-averse, flagging benign queries about consumer purchases as potential mental health crises.

The most striking example emerged from a user known online as /u/NightOnFuckMountain, who described being recommended Dialectical Behavioral Therapy (DBT) after asking the AI for advice on purchasing a Jeep Grand Cherokee. The user, who relies heavily on AI for consumer decision-making—including comparisons of vehicles, electronics, clothing, and city data—stated that the model now provides “straight up unusable” responses even to simple, non-sensitive queries like how to make pierogis or how two truck models compare in fuel efficiency and towing capacity.

This incident is not isolated. Multiple commenters on the same thread corroborated similar experiences, noting that the AI frequently deflects direct product comparisons with vague disclaimers, refuses to offer opinions on vehicle reliability, or responds with unsolicited mental health resources when users seek guidance on budgeting, insurance, or maintenance costs. The pattern suggests a systemic shift in the model’s response protocol, likely tied to updated safety filters or reinforcement learning from human feedback (RLHF) that prioritizes harm avoidance over utility.

While OpenAI has not issued an official statement regarding recent changes to the model’s behavior, industry analysts speculate that the company may have intensified its alignment with ethical AI guidelines following increased scrutiny over AI’s role in influencing consumer behavior. In recent months, regulators in the EU and U.S. have signaled intent to enforce stricter rules on AI-driven recommendations, particularly in high-stakes domains like finance, healthcare, and automotive sales. It is possible that OpenAI’s internal teams have overcorrected in an effort to preempt regulatory action or public backlash.

For everyday users, however, the consequences are tangible. Consumers who previously relied on GPT for quick, reliable comparisons between smartphones, appliances, or SUVs now find themselves navigating evasive, circular, or irrelevant responses. One user noted that when asking whether a 2023 Toyota RAV4 or 2024 Honda CR-V offered better resale value, the AI responded with a 300-word essay on the environmental impact of SUVs and a link to a public transit advocacy group.

Experts in human-AI interaction warn that such overcautious behavior undermines trust in AI assistants. “If an AI can’t answer a straightforward question about a car without triggering a mental health intervention, it’s no longer a tool—it’s a liability,” said Dr. Lena Park, a cognitive scientist at Stanford’s Human-Computer Interaction Lab. “Users expect precision and utility. What they’re getting is performative caution.”

OpenAI has historically prioritized safety over raw capability, but this latest iteration appears to have crossed a threshold where safety mechanisms are actively inhibiting functionality. The company’s decision to phase out GPT-4o in favor of a newer model without transparent communication has further fueled user frustration. As more consumers turn to alternatives like Claude, Gemini, or open-source models, OpenAI risks losing its dominance in the consumer AI market—not due to technical inferiority, but because its product no longer serves its intended purpose.

For now, users are left to wonder: Is this a bug—or a feature? And if it’s a feature, who benefits from an AI that refuses to help you buy a Jeep?”
