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.

Free, open-source, local-first developer workspace for snippets, notes, APIs and diagrams
Organize reusable code fragments in nested folders, tag them for fast filtering, and jump to anything through a keyboard-driven command palette.
Write Markdown notes, explore connections between them in a graph view, and turn notes into tasks with status, priority, due dates and links to related snippets and requests.
Save API requests, run them in sequence, pass values between steps, and inspect responses or JSON diffs without leaving the app.
Connect OpenAI, Anthropic, Gemini, DeepSeek, Mistral, xAI or OpenRouter with your own key, or use a local Ollama/LM Studio model, to edit code, reorganize notes and test APIs. An MCP server exposes the same vault to external AI agents.
