Hugging Face (https://huggingface.co) is something like GitHub for LLMs, Datasets etc. It will give your team the opportunity to test a variety of LLMs, both open source and proprietary, including OpenAI's, Microsoft's, and Google's models. Through my research I have found that while some models may not currently be the best in the market, they show great potential to become very good in the near future, particularly in the healthtech or fintech market.
