A multi-platform AI chat client that connects to any model you choose
Configure the AI providers or API keys you already use, and switch between them inside the client instead of committing to a single bundled service.
Native apps for Windows, macOS, Linux, iOS and Android keep your conversations and settings aligned across devices.
Drag in PDF, Word, Excel, PowerPoint, code and image files and let the model summarise, extract or analyse the content directly.
Edit the same image across multiple turns, automatically carrying over the previous version and merging several images while keeping subjects consistent.
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.
