DeepSeek

Overview DeepSeek is the Chinese open source AI lab whose R1 model release in January 2025 broke the pricing floor of the entire AI industry and forced OpenAI, Anthropic, and Google to publicly rework their reasoning model roadmaps within weeks. Founded in 2023 as a spin off from High Flyer, a quantitative hedge fund in Hangzhou, DeepSeek is now on the V3.2 and R2 model families in 2026, and it operates one of the strongest freely usable AI assistants on the internet — chat.deepseek.com — at a price of zero for the consumer product and roughly one tenth the cost of Claude or GPT 5 on the API side. DeepSeek's product identity is defined by two structural facts nobody else in the frontier tier can match: the models are open weight and downloadable under permissive licenses, and the pricing is aggressive enough that developers routinely rebuild AI features they had shelved as too expensive with GPT 4 or Claude 3. The chat product itself is minimal — a clean web interface, mobile app, no plugin marketplace, no image generator you would pick over DALL E, no video model — but the model quality on reasoning, math, and code is genuinely competitive with the frontier three at a fraction of the operating cost. The one line positioning: DeepSeek is the AI assistant to pick when cost is a constraint, when you want to run a frontier class model on your own hardware, or when you want the strongest math and coding…
