This document provides an overview of different GPT-3 models and their capabilities. It recommends starting with the Davinci model for best results on complex tasks, then optimizing for other models based on latency needs. The Davinci model excels at understanding intent and explanations but requires more resources. The Curie model is powerful and fast, suitable for translation and sentiment analysis. The Babbage model handles basic classification and search. The Ada model is fastest for basic parsing and extraction tasks.
