It's been a great effort by the early and growing American open-model labs since last June to put the US much more back on the map. We were getting totally owned last June.

Nvidia, Ai2, Arcee, Gemma, GPT-OSS and a few others will be seen as saving American open AI.

Generally it's the who's who of people who released useful models from June 2025 to June 2026. Nemotron Ultra 3 seems like a watershed moment in how the equilibrium is viewed long term.
