Why Bigger Isn’t Always Better for Language Models

The article discusses why bigger isn't always better for language models in AI. It highlights how OpenAI's GPT-4 model, with over 1.7 trillion parameters, is not necessarily superior to smaller alternatives like Falcon 40B-instruct and Alpaca 13B. The article argues that larger models are more expensive to train and deploy, harder to control and fine-tune, and can exhibit counterintuitive performance characteristics. It also points out that users often seek alternatives that are less costly and better suited for their needs. Furthermore, the article mentions how smaller language models can be trained using imitation learning techniques from larger models like GPT-4, offering a more balanced mix of performance, cost, and usability.
