Introduced last week, the Open-Source AI Leadership Act, H.R. 10152, would direct the [US Department of Commerce](https://www.scmp.com/topics/us-commerce-department?module=inline&pgtype=article)to identify barriers to adopting US open-weight models and compile data on their adoption relative to Chinese ones.Open-weight, or open-source, models are AI models that are released freely over the internet, allowing users with the necessary hardware to download and customise them for their own use. While leading US AI models including [OpenAI’s GPT](https://www.scmp.com/search?q=OpenAI?module=inline&pgtype=article)and[Anthropic’s Claude](https://www.scmp.com/topics/anthropic?module=inline&pgtype=article)are mostly closed-source, meaning that they can only be accessed through official channels, most leading Chinese models are released as open-weight models.Advertisement Select Voice Select Speed 1.00x
