Many models

While most of the attention in artificial intelligence (AI) focuses on well-known consumer facing services like ChatGPT, Midjourney, and Perplexity, the number of notable machine learning models released each year is accelerating, according to Stamford University’s annual AI index report issued this month. Given the cost of training AI, industry continues to lead the release of new models, however the number of new models built in collaboration between academia and industry reached a new high in 2023. Significantly, 66% of notable large models today are open source, allowing researchers to customize the tools for particular applications and create new versions of the models.
