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.

Pick from neural AI voices with five reading styles so the output sounds like a person rather than a satnav, and set speed from 0.5x up to 2x.
Each sentence is highlighted while it is read, so you can follow along on screen, which is what makes it work for studying and proofreading by ear.
Paste plain text or upload a document, or drop in a link and the article text is extracted for you before playback.
Download the generated audio as an MP3 and keep it for commuting, the gym or any podcast app—no repeated regeneration needed.
