A Guide to OpenAI: How to Choose the Best Language Model For Your AI Application

Exploring the capabilities and differences among OpenAI's Large Language Models (LLMs), this text provides an in-depth overview of the available text models, focusing on their unique features, applications, and cost implications. Initially, the author experimented with GPT-3.5 but expanded their exploration with the release of GPT-4, which offers more coherent, accurate, and creative text along with multi-modal capabilities. The text emphasizes the distinctions between completion and chat models, noting that OpenAI's future focus appears to be on chat models due to their conversational abilities. It also discusses the importance of fine-tuning models for specific tasks to improve performance and reduce costs, as well as the significance of token capacity and parameter size in determining a model's capabilities. The "gpt-3.5-turbo" series is highlighted for its cost-effectiveness, making it a popular choice for developing minimum viable products despite the additional benefits larger models like GPT-4 offer. The text advises careful consideration of application needs and budget constraints when selecting a model and suggests using the OpenAI playground for precise control over model interactions.
