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 any document into AI-ready context with agentic parsing and extraction
Content is routed to specialized expert agents for text, tables, charts and images, with recursive auto-correction loops that raise pass-through rates on messy scans and multi-modal documents.
Define the output schema you need and extraction agents return structured JSON per document, page or table row — with citations and confidence scores — without any model training.
Categorize documents with natural-language rules, segment them into logical sections, and use enterprise-grade chunking and embedding pipelines optimized for retrieval precision.
Choose Cost Effective, Agentic or Agentic Plus parsing per page, or let Auto Mode route pages to the cheapest tier that satisfies your quality bar, saving up to 80%.
