This is, I'm sorry to say, simply not true. Anthropic and Open AI are materially ahead of every open source model out there at this time. The best they can hope to do is be Sonnet-adjacent, and even then I have not seen it.

They aren't. Any difference is in sampling parameters and post-training flavor choices. These aren't things that are "materially ahead", that's basically just LLM themes.
