Nathan Lambert is an AI research scientist at Ai2. He highlights internal benchmark results comparing Ai2's open OLMo 3 7B model to Meta's widely used Llama 3.1 8B.
“And I just think of this cause like Lama 3.1 AP is one of the most used models and hugging base of all time. And this should be better. We're, In our measurements, we see it as being better than Llama.”
