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.
AI that fills your PDF and Word forms for you
Automatically detects and maps every field in a flat PDF or Word form, using semantic understanding rather than rigid templates.
Each filled field can display its source and the reasoning behind the value, making verification fast and auditable.
Runs concurrent parallel field filling and handles structured row data, so multi-form packets and repeating tables are completed together.
An MCP server lets you fill PDFs from inside Claude Desktop, Code, or ChatGPT, plus n8n and Zapier automations for wider workflows.
