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.
AI-powered test management that keeps QA teams fast and organized
Paste a requirement or spec and get draft test cases covering happy path, edge, and negative scenarios, shaped by configurable AI rules for tone, format, and naming.
Store cases in structured folders, apply tags and priorities, reuse shared steps and preconditions, and filter across projects in seconds.
Build runs with live updates, fixed folder structures, or locked versions, and use parameterized cases to cover multiple scenarios from one template.
Dashboards show coverage, execution status, team performance, and a full traceable path from requirement to result.
