About DeepSeek
DeepSeek shook the industry by matching frontier-class reasoning with open weights and API prices an order of magnitude below Western rivals. The chat app is free and capable, but the real story is the API: developers get strong reasoning and coding performance at prices that make previously uneconomic AI features viable. Data residency in China is the trade-off to weigh.
