*GPT-4.5: More Thoughtful, More Expensive, Less Hallucination-Prone* https://www.techzim.co.zw/2025/02/gpt-4-5-more-thoughtful-more-expensive-less-hallucination-prone/ You can’t even blink with these AI models. Every other day, you hear about “life-changing” new features. Most of it is exaggerated, but it’s still impressive. OpenAI and ChatGPT have the limelight today. OpenAI has unveiled GPT-4.5, its most advanced language model to date. They say it has improved emotional intelligence and conversational depth. CEO Sam Altman says GPT-4.5 is “the first model that feels like talking to a thoughtful person.” Being the salesman that he is, he says he was pleasantly surprised when he received genuinely good advice from the AI. `Stay updated.

This should make the AI’s interactions feel more natural and empathetic. It allows the model to provide nuanced support, such as offering comfort during challenging times. I don’t know anyone looking for this kind of support, but it’s there now. OpenAI demonstrated how the new model handles a request to write an angry text to a friend. GPT-4.5 manages the situation better, as an example. Although, one could argue it performed worse because it strayed further from the request and tried to play the role of a responsible aide, stopping you from sending a text you might regret. Listen, if you vent to your AI, then more power to you, I guess. *Reduced Hallucinations* GPT-4.5 has a lower tendency to generate inaccurate or fabricated information across various topics. Now, this is huge. The model generates fewer inaccuracies compared to GPT-4. It has a lower hallucination rate of 37.1%, compared to GPT-4o’s 61.8%. The AI hallucination problem persists, and any update that reduces it will always be welcome. *Improved Performance* As you would expect, with an expanded dataset and improved training techniques, GPT-4.5 offers deeper contextual understanding across diverse topics. GPT-4.5 excels in tasks like writing, programming, and problem-solving, making it a versatile tool for both personal and professional applications. *Not Free for Now* However, these advancements come with increased computational demands. Altman says GPT-4.5 is a “giant, expensive model” and adds that GPU shortages have limited its immediate availability. Currently, GPT-4.5 is accessible to ChatGPT Pro subscribers and developers via the API, with plans to expand to other subscription tiers as more GPUs become available.
