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.

Detect AI writing, humanize the flagged sentences, then recheck in the same tab
Every sentence gets its own AI confidence score and colour code inside your text, so you can see which lines to fix instead of reacting to one blunt overall verdict. Sentence-level detail starts on the Starter plan.
A 0–100 score that rises as your writing becomes more natural, recomputed on every scan so you can watch the number move as you edit.
The humanizer rewrites only the passages that read as AI-written, keeping your meaning and tone. Free accounts get around 260 words per rewrite; paid plans add thousands of words a month plus Advanced, Business and Casual modes.
Detection, rewriting and re-scoring happen in one window. After a humanize pass you recheck the same text and compare the before-and-after AI percentage side by side.
