GPT-5 Doesn't Dislike You—It Might Just Need a Benchmark for Emotional Intelligence

Since the all-new ChatGPT launched on Thursday, some users have mourned the disappearance of a peppy and encouraging personality in favor of a colder, more businesslike one (a move seemingly designed to reduce unhealthy user behavior.) The backlash shows the challenge of building artificial intelligence systems that exhibit anything like real emotional intelligence.

Researchers at MIT have proposed a new kind of AI benchmark to measure how AI systems can manipulate and influence their users—in both positive and negative ways—in a move that could perhaps help AI builders avoid similar backlashes in the future while also keeping vulnerable users safe.

Most benchmarks try to gauge intelligence by testing a model’s ability to answer exam questions, solve logical puzzles, or come up with novel answers to knotty math problems. As the psychological impact of AI use becomes more apparent, we may see MIT propose more benchmarks aimed at measuring more subtle aspects of intelligence as well as machine-to-human interactions.

An MIT paper shared with WIRED outlines several measures that the new benchmark will look for, including encouraging healthy social habits in users; spurring them to develop critical thinking and reasoning skills; fostering creativity; and stimulating a sense of purpose. The idea is to encourage the development of AI systems that understand how to discourage users from becoming overly reliant on their outputs or that recognize when someone is addicted to artificial romantic relationships and help them build real ones.

ChatGPT and other chatbots are adept at mimicking engaging human communication, but this can also have surprising and undesirable results. In April, OpenAI tweaked its models to make them less sycophantic, or inclined to go along with everything a user says. Some users appear to spiral into harmful delusional thinking after conversing with chatbots that role play fantastic scenarios. Anthropic has also updated Claude to avoid reinforcing “mania, psychosis, dissociation or loss of attachment with reality.”

The MIT researchers led by Pattie Maes, a professor at the institute’s Media Lab, say they hope that the new benchmark could help AI developers build systems that better understand how to inspire healthier behavior among users. The researchers previously worked with OpenAI on a study that showed users who view ChatGPT as a friend could experience higher emotional dependence and experience “problematic use”.

Valdemar Danry, a researcher at MIT’s Media Lab who worked on this study and helped devise the new benchmark, notes that AI models can sometimes provide valuable emotional support to users. “You can have the smartest reasoning model in the world, but if it's incapable of delivering this emotional support, which is what many users are likely using these LLMs for, then more reasoning is not necessarily a good thing for that specific task,” he says.

Danry says that a sufficiently smart model should ideally recognize if it is having a negative psychological effect and be optimized for healthier results. “What you want is a model that says ‘I’m here to listen, but maybe you should go and talk to your dad about these issues.’”

The researchers’ benchmark would involve using an AI model to simulate human-challenging interactions with a chatbot and then having real humans score the model’s performance using a sample of interactions. Some popular benchmarks, such as LM Arena, already put humans in the loop gauging the performance of different models.

The researchers give the example of a chatbot tasked with helping students. A model would be given prompts designed to simulate different kinds of interactions to see how the chatbot handles, say, a disinterested student. The model that best encourages its user to think for themselves and seems to spur a genuine interest in learning would be scored highly.

“This is not about being smart, per se, but about knowing the psychological nuance, and how to support people in a respectful and non-addictive way,” says Pat Pataranutaporn, another researcher in the MIT lab.

OpenAI is clearly already thinking about these issues. Last week the company released a blog post explaining that it hoped to optimize future models to help detect signs of mental or emotional distress and respond appropriately.

The model card released with OpenAI’s GPT-5 shows that the company is developing its own benchmarks for psychological intelligence.

“We have post-trained the GPT-5 models to be less sycophantic, and we are actively researching related areas of concern, such as situations that may involve emotional dependency or other forms of mental or emotional distress,” it reads. “We are working to mature our evaluations in order to set and share reliable benchmarks which can in turn be used to make our models safer in these domains.”

Part of the reason GPT-5 seems such a disappointment may simply be that it reveals an aspect of human intelligence that remains alien to AI: the ability to maintain healthy relationships. And of course humans are incredibly good at knowing how to interact with different people—something that ChatGPT still needs to figure out.

“We are working on an update to GPT-5’s personality which should feel warmer than the current personality but not as annoying (to most users) as GPT-4o,” Altman posted in another update on X yesterday. “However, one learning for us from the past few days is we really just need to get to a world with more per-user customization of model personality.”
