DeepSeek is one of the most closely watched Chinese model families, associated with reasoning, coding, open models, and cost-efficient training and inference. Its releases often trigger debate around architecture, training cost, inference efficiency, open strategy, and the global competitive landscape.

DeepSeek can be understood through three themes: how reasoning models improve math, coding, and complex problem solving; how open models reshape developer and cloud ecosystems; and whether cost efficiency makes high-capability models accessible to more companies and individuals.
