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.

The detector returns an assessment of how much of a submitted passage reads as AI-generated, based on a model trained on a very large mixed corpus of human and machine text.
Runs complete in seconds so you can screen drafts, student essays or client copy during your normal editing pass.
Each submission handles roughly 2,000 characters at once, enough for an abstract, an email, a product description or an article excerpt.
The detector is built for anyone who needs a quick authenticity read rather than a forensic report, with no complex setup or account requirements.
