OpenAI has unveiled GPT-4.5, the latest advancement in its chat model series, claiming it to be the best iteration yet. Initial tests show that GPT-4.5 exhibits improved emotional intelligence and warmth in conversations compared to older models. A notable example of this is its empathetic response to users sharing difficult experiences. The enhancements in GPT-4.5 are attributed to advancements in unsupervised learning, which expanded its knowledge base and understanding of context. While the model reduces hallucination rates significantly, it does not completely eliminate the issue, marking progress in AI reliability.
In early testing, OpenAI says people found GPT-4.5 to be a more natural conversationalist, with the ability to convey warmth and display a kind of emotional intelligence.
The gains shown by GPT-4.5 are the result of advancements OpenAI made in unsupervised learning, leading to a model that has broader knowledge and a deeper understanding of the world.
GPT-4.5 beat out o3-mini, GPT-4o and even o1 with a hallucination rate of 37.1 percent, showing it is a step in the right direction.
When powered by GPT-4.5, the chatbot responds with empathy by asking, 'Want to talk about what happened, or do you just need a distraction?'
Despite its relative strengths over GPT-4o and o3-mini, GPT-4.5 isn’t a definitive solution to AI hallucinations, but it's a significant improvement.
