If you are only looking at US hosting providers, models from US labs easily meet or beat models from Chinese labs on the same intelligence level. I'm not comparing DeepSeek with Opus because those are on different levels of performance.

Deepseek v4 Pro on US hosting is like 1.5x cheaper and 5x cheaper on input/output compared to Sonnet, and that's not even a fair comparison because Deepseek is much stronger than Sonnet. It's more reasonable to compare with Opus 4.5, which is much more expensive.
