Just realized that there are basically no American open models right now ever since the Llama series was abandoned. Basically Gemma and GPT-OSS I guess?
Ah but Mira Murati's new Inkling is Apache 2.0
But it makes sense that if you're a university researcher you are thinking about what's a model that will be open weight and developed over the long term and doesn't raise 'Chyna' concerns in Washington DC
I would not be shocked if another open model eventually shakes out of Facebook (based on Zuckerberg's public remarks).
Also Nemotron and Arcee.
Laguna is the most recent and capable one that comes to mind. In its size class it is not as "smart" in my experience as qwen 3.5 122 or DeepSeek v4 flash 0731 (all at q8), but it's also not terrible.
review of AllenAI Olmo research team and commitment to OSS -- AI2 complete transparency including training data, code, intermediate checkpoints, and detailed logs for reproducibility and scientific rigor.
I've used Inkling a lot recently, it's an American open model and is really good!
Laguna S 2.1 is another fairly impressive-for-the-size American open model
There's a bunch of American open models. Inkling, Nemotron, Trinity come to mind, but I'm sure there's others.
