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.

Intelligent model routing for coding agents
Predicts the best model and reasoning effort for each step of a session by weighing prompt semantics, cache state, sub-agent structure and past session outcomes.
Works alongside the coding-agent harness and model gateway you already use, so recommendations execute inside your own stack without locking you into a single provider.
Can route using only derived request metadata and locally computed features, so Not Diamond never sees your payloads, inputs or outputs.
Reinforcement learning from feedback signals and session results personalizes recommendations per developer and transfers learnings across an organization.
