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.

An AI writing workspace that drafts from page-cited evidence and reviews your document's integrity
The ChatPDF tool answers questions about a paper using retrieved excerpts and verifies citations verbatim, so answers stay tied to a specific page.
Turn an approved outline and selected evidence into a draft in a resumable workspace that carries your quotes forward without pasting blind.
Findings must quote your document verbatim and are discarded if the excerpt cannot be found, so every flag points to something you can check.
The AI Detector surfaces review signals you can inspect rather than a single black-box percentage, and is framed as supporting evidence.
