For the general public, OpenAI’s ChatGPT models are currently the most popular and well-known LLMs. However, there are many other LLMs available in the market that fit a myriad of purposes. You do not always need to use the most expensive, most powerful LLM. Some LLMs focus on one area, such as the Meditron LLMs, which are medical research-focused fine-tuned versions of Llama 2.
