About DeepSeek
What it is
DeepSeek is a Chinese AI lab that publishes its frontier models as open weights and runs them as a free web and mobile assistant with reasoning and search, alongside a paid API and documentation for building against it.
Why it's different
Its significance is the combination: frontier-adjacent capability, open weights, and API pricing far below the Western labs, which changed what the rest of the market could charge. Reasoning models you can download and run yourself is the part that matters long term. The considerations are real and worth stating plainly: the hosted service is subject to Chinese jurisdiction and content rules, so anything sensitive belongs on weights you host, not on their servers.
How people use it
Reasoning and coding tasks where API cost is the limiting factor. Running a strong open model on your own hardware. A free second opinion against whichever assistant you pay for. Use the open weights rather than the hosted service for anything confidential, because that choice is where the jurisdiction question is actually settled.
