High-efficiency open-weight and hosted reasoning AI powered by DeepSeek-V4 and R1 at ultra-low token costs.
Leverages a sparse Mixture-of-Experts architecture (49B active parameters out of 1.6T on V4-Pro) to process up to 1 million tokens with minimal latency and memory overhead.
Pioneered by DeepSeek-R1 and integrated into V3.2 and V4 thinking modes, exposing step-by-step self-verification for complex math, logic, and code debugging.
Drops input token costs to $0.003/1M on Flash and $0.022/1M on V4-Pro for cache hits, with 50% lower rates during off-peak UTC hours.
Provides free access at chat.deepseek.com and on iOS/Android with document uploads, reasoning mode, and web search without paywalling core models.
Turn teaching material into quizzes your class can take
Generate quizzes from pasted text, a web URL, a text-based PDF or a YouTube video, then set the class level before reviewing the draft.
Review and adjust every generated question and answer before assigning, or import an existing quiz instead of retyping it.
Add a class roster once and share a link plus private per-student access codes, with no student email or password signup.
Multiple-choice answers are scored against your key, while AI-suggested marks for written answers wait for your approval and pending marks are flagged separately.
