67.8

The open reasoning model that started it all — RL-trained chain-of-thought, MIT licensed, and a research landmark.

Grok 4

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

Grok 4 wins 3 of the 3 benchmarks these models share, against 0 for DeepSeek R1 (0528). On price the gap is dramatic: DeepSeek R1 (0528) works out roughly 6.3x cheaper per blended million tokens. Grok 4 also takes 256K of context versus 128K for DeepSeek R1 (0528). And DeepSeek R1 (0528) is open-weights (MIT), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
