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.

Protect every human and AI browser action — without a new browser
PixieBrix deploys as a managed extension to monitor human and AI actions in any web app — including third-party sites — with full browser context that network controls miss.
Configure group policies in minutes to monitor, warn, soft-block or block actions, with built-in contact-centre and anti-fraud controls plus AI-code and low-code custom controls.
Cover refund and discount integrity, shipping and loyalty fraud, payment-card masking, and flag snooping, bulk exports and after-hours activity.
Every browser action is logged with on-screen context, backed by user risk scoring and an MCP investigation server for correlating data sets.
