> I also think the US is going to ban all non-US LLM providers from the US market soon for "security reasons."
Well Trump is interested in tariffing movies and South Korea took DeepSeek off mobile app stores, so they certainly may try. But for high-end tasks, DeepSeek R1 671B is available for download, so any company with a VPN to download it and the necessary GPUs or cloud credits can run it. And for consumers, DeepSeek V3's distilled models are available for download, so anyone with a (~4 year old or newer) Mac or gaming PC can run them.
If the only thing keeping these companies valuations so high is banning the competition, that's not a good sign for their long-term value. If you have to ban the competition, you can't be feeling good about what you're making.
For what it's worth, I think GPT o3 and o1, Gemini 2.5 Pro and Claude 3.7 Sonnet are good enough to compete. DeepSeek R1 is often the best option (due to cost) for tasks that it can handle, but there are times where one of the other models can achieve a task that it can't.
But if the US is looking to ban Chinese models, then that could suggest that maybe these models aren't good enough to raise the funding required for newer, significantly better (and more expensive) models. That, or they just want to stop as much money as possible from going to China. Banning the competition actually makes the problem worse though, as now these domestic companies have fewer competitors. But I somewhat doubt there's any coherent strategy as to what they ban, tariff, etc.
