DeepSeek V4 vs Grok 4
Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
DeepSeek · Mar 2026
The open-weights shock of 2026: ~81% SWE-bench Verified, a 1M context and MIT license at $0.30/$0.50 per million tokens.
xAI · Jul 2025
xAI's mid-2025 flagship, trained on the 200K-GPU Colossus cluster — a math and science reasoning standout of its generation.
The verdict
These two models don't yet share verified results on the benchmarks we track, so judge them on specs, pricing and intended use. On price the gap is dramatic: DeepSeek V4 works out roughly 17x cheaper per blended million tokens. DeepSeek V4 also takes 1M of context versus 256K for Grok 4. And DeepSeek V4 is open-weights (MIT), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
