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.

factfully is a Chrome extension that acts as an AI-driven misinformation checker, evaluating statements in the pages you read and helping you gauge whether content is likely true or biased.
Ranks statements across metrics such as sensationalism, testability, and political bias to flag likely false content.
Tokenization separates objectively checkable claims from subjective opinions before verification.
Scans thousands of websites to see whether a statement is backed by other sources.
Delivered as a Chrome extension so checks sit alongside the content you are reading.
