DeepSeek V3.2 Exp vs LongCat 2.0
LongCat 2.0 leads DeepSeek V3.2 Exp on the Artificial Analysis Intelligence Index, 19.1 to 16.6, and DeepSeek V3.2 Exp costs 2.9x less per output token ($0.41 vs $1.20 per million). Updated October 22, 2026; 4 benchmarks have a result for both.
DeepSeek V3.2 Exp or LongCat 2.0: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick DeepSeek V3.2 Exp for output tokens 2.9x cheaper ($0.41 vs $1.20 per million) and work measured by AA Intelligence Index or Humanity's Last Exam (Artificial Analysis run), where it leads.
