Practical guideAbout this publication
Practical guidance for a fast-changing AI ecosystem
DeepSeek helps readers distinguish DeepSeek products, models, access routes, costs, and claims using dated, inspectable sources.
Purpose
We translate technical and commercial documentation into practical guidance for users, developers, students, and evaluators. We do not sell DeepSeek access or provide account support.
Coverage
The publication covers hosted chat, first-party API use, current and historical models, local deployment, pricing, comparisons, privacy, safety, and troubleshooting.
Verification
Primary sources are preferred. Changing facts carry verification dates and are tracked centrally so model IDs, prices, limits, policies, and availability can be rechecked consistently.
Limits
Current material is documentation-based. No authenticated product, paid API, load, benchmark, mobile, or local-hardware test record was supplied, and the site does not imply otherwise.
Evidence hierarchy
Primary sources come first
Product pages, API documentation, release notes, repositories, model cards, status pages, and legal policies provide the first layer. Strong third-party reporting and research may add context, but a competitor, affiliate, anonymous post, or search snippet does not establish a volatile claim on its own.
