DeepSeek vs ChatGPT vs Claude (2025)

DeepSeek R1 shocked the AI world with GPT-4 level performance at a fraction of the cost. But can it actually replace ChatGPT or Claude for daily use?

TL;DR: DeepSeek R1 is impressive for math and reasoning (on par with GPT-4o). ChatGPT still wins for features and versatility. Claude still wins for writing quality. DeepSeek’s advantage: completely free, open-source, runs locally. Privacy concern: data goes through Chinese servers.
