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.

Rather than juggling separate subscriptions, Nova puts multiple frontier chat models behind a single prompt box so you can pick the right one per task.
Conversations carry across iPhone, iPad, Apple Watch, Mac, Android, and the web app, so you are not locked to one screen.
It drafts, rewrites, tightens, and critiques prose for essays, professional documents, social posts, and creative writing.
Step-by-step explanations for essays, compositions, and math questions, aimed at students who need to understand rather than copy.
