>but after Deepseek stunned the world with the R1 model, subsequent models got heavily censored and languished in relative obscurity.

I'm pretty sure this isn't what happened. DeepSeek just hasn't released a big model upate. But in the meantime, Qwen, Bytedance, Ziphu and Moonshot AI have released extremely impressive models, some of which are SOTA or close to it. The open source/open weight world is still in love with Chinese labs as they keep releasing cool stuff and filling the void left by Meta and Mistral.
