The current balance of power in open models

The article discusses the current state of open models, which refer to pre-trained models made available for use by anyone, often without restrictions or licensing fees. The author notes that the landscape of open models is rapidly changing, with new models being released at an incredible pace. The author identifies four key players in the open model space: Hugging Face's Transformers, which has over 1 million pre-trained models available, LLaMA, which is an AI model developed by Meta that has shown strong performance in various tasks, and PaLM 3, a model developed by Meta that has achieved state-of-the-art results in several tasks. The author also mentions Google's BERT, which is a pre-trained language model that has been widely adopted. The article highlights the importance of open models in accelerating AI research and development, and notes that the current balance of power in the open model space is shifting rapidly as new models are released and existing ones are improved.
