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.

Chat with ChatGPT instead of typing keywords into a search bar
Ask questions in natural language instead of assembling keywords, and receive a written answer rather than a page of blue links.
The extension sits in the Chrome toolbar, so the assistant is one click away from any tab you happen to be on.
Responses are generated by ChatGPT, giving you a familiar chat-style experience inside the browser itself.
The package is a small download and installs in seconds, with no separate account signup required by the extension itself.
