Comparing the efficiency in response time between GPT-4.5 and GPT-4o involves understanding the advancements and design goals of each model. While specific response time metrics for GPT-4.5 are not detailed in the available information, we can infer its efficiency based on its design and improvements over previous models.
**GPT-4o is designed to be quicker and more computationally efficient than GPT-4, with a focus on multimodal capabilities and faster response times. It is capable of responding to voice inputs in as little as 232 milliseconds, averaging around 320 milliseconds, which is comparable to human conversational response times[4]. However, recent tests have shown mixed results, with GPT-4 sometimes outperforming GPT-4o in response times for certain tasks[2].
**GPT-4.5, on the other hand, is noted for improving on GPT-4's computational efficiency by more than 10 times[3][5]. This significant improvement suggests that GPT-4.5 is designed to handle complex tasks efficiently without sacrificing speed, which could imply faster or more consistent response times compared to GPT-4o in certain scenarios. However, specific response time comparisons between GPT-4.5 and GPT-4o are not provided in the available information.
In summary, while GPT-4o is known for its efficiency and multimodal capabilities, GPT-4.5's substantial improvement in computational efficiency could potentially offer faster or more consistent response times in complex tasks. However, direct comparisons of response times between these models are not explicitly stated in the available data.
