GPT-4’s improvements over GPT-3.5, like with many subsequent iterations in machine learning models, typically come from a combination of increased model size, refined architecture, better training data, and lessons learned from previous models. As of my last update in September 2021, specific details on GPT-4’s improvements hadn’t been officially detailed by OpenAI. However, based on general advancements in AI models, one can anticipate the following improvements from GPT-4 over GPT-3.5:

Larger Model Size:
This allows the model to store and process more information. A larger model can capture more nuances in data and understand context better.Better Training Data:
With each iteration, the quality and quantity of training data can be improved, which can lead to better performance in terms of understanding and generating human-like text.Refined Architectures:
Over time, the underlying neural network architectures might be tweaked to better handle certain tasks or to be more efficient in terms of computation.Training Techniques:
New and improved training methodologies can lead to better generalization and less overfitting. Techniques like regularization, novel loss functions, or improved optimization strategies might be employed.Feedback Loop:
OpenAI might have incorporated feedback from users of GPT-3.5 and other prior models to address limitations and optimize performance in specific areas.Specialized Components:
There’s always a possibility that newer versions contain specialized components or modules that make them perform better on specific tasks.Improved Safety and Ethical Considerations:
One of the concerns with earlier GPT models was their propensity to generate inappropriate or biased content. Subsequent versions likely focus on addressing these issues to make the model safer and more reliable.Efficiency Improvements:
Over time, models can be optimized to run faster and require less computational power, even if they are larger. This could be due to both architectural tweaks and software optimizations.
To get the most accurate and detailed information on the improvements of GPT-4 over GPT-3.5, it would be best to refer to any official documentation or papers released by OpenAI after 2021.
