GPT-4.5 and GPT-4o are both advanced AI models developed by OpenAI, but they have different strengths and use cases. Here are the main areas where GPT-4.5 outperforms GPT-4o:
1. Math and Science Performance
GPT-4.5 shows significant improvements over GPT-4o in math and science, with a 27.4% increase in math performance and a 17.8% increase in science performance[4]. This makes GPT-4.5 more reliable for factual reasoning tasks, which are crucial in fields like education, research, and professional services.2. Multilingual and Multimodal Capabilities
While GPT-4o is designed with strong multimodal capabilities, allowing it to process text, audio, and visual data[8], GPT-4.5 also sees moderate gains in multilingual and multimodal performance, with a 3.6% and 5.3% increase, respectively[4]. However, GPT-4.5 does not support multimodal output like audio or video[6].3. Pattern Recognition and Creativity
GPT-4.5 is adept at recognizing patterns and has enhanced creativity, making it better suited for tasks that require nuanced understanding and creative writing[6]. This is beneficial in applications such as content creation, marketing, and creative problem-solving.4. Reliability and Hallucinations
GPT-4.5 is designed to hallucinate less than previous models, providing more reliable performance across a wide range of general topics[6]. This reliability is crucial for tasks where accuracy is paramount, such as legal research or medical applications.5. Conversational Style
GPT-4.5 offers a more natural conversational style, which is advantageous for applications requiring rich and engaging interactions, such as customer service chatbots or educational tools[6].In summary, while GPT-4o excels in multimodal tasks and real-time applications, GPT-4.5 is superior in areas requiring detailed factual reasoning, pattern recognition, and creative tasks. GPT-4.5's reliability and conversational capabilities also make it a better choice for applications where nuanced understanding and accuracy are critical.
