DeepSeek-V3.2-Exp

OPEN

DeepSeek · DeepSeek-V3 family · released Sep 29, 2025

Experimental release that debuted DeepSeek Sparse Attention (DSA), cutting single-token inference FLOPs/KV-cache substantially for long-context use while holding benchmark performance roughly on par with V3.1-Terminus. API prices cut 50%+ at launch: input cache-hit $0.028/M, cache-miss $0.28/M, output $0.42/M (vs. $0.07/$0.56/$1.68 under V3.1-Terminus). Superseded by DeepSeek-V4-Flash as the alias target for deepseek-chat/deepseek-reasoner starting Dec 2025, and by the V4 series generally in 2026.
