Claude Haiku 4.5 vs DeepSeek V3.2
Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
Anthropic · Oct 2025
Anthropic's fast tier: Sonnet-4-class coding performance at $1/$5 and more than twice the speed.
DeepSeek · Sep 2025
The sparse-attention release that halved DeepSeek's already-lowest-in-class prices while keeping GPT-class quality.
The verdict
Claude Haiku 4.5 and DeepSeek V3.2 split the 2 benchmarks they share evenly (1–1), so capability alone won't settle this one. On price the gap is dramatic: DeepSeek V3.2 works out roughly 6.3x cheaper per blended million tokens. Claude Haiku 4.5 also takes 200K of context versus 128K for DeepSeek V3.2. And DeepSeek V3.2 is open-weights (MIT), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
