Not only are there many American open weight models as others have mentioned, but Americans are the only ones doing actual open source models [0]. Not just distributing binary blobs and calling them "open".

There is no question this is true for the Chinese open LLMs. GPT-OSS had a small moment of interest, arguably it was a success as an open model for a while but it’s not relevant now. The early llamas were probably the most successful for their time.
Allenai / olmo was never relevant as far as I can tell. It’s not super helpful, especially as a sovereign government initiative to build an also-ran, they should be going for real relevance.
By releasing models with open-weights, DOE seeks to galvanize the scientific and AI communities around shared infrastructure for science: enabling new workflows in materials discovery, energy systems, earth systems modeling, fusion, biology, high-energy physics, and beyond.
