67.8

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

Gemini 2.5 Pro

Google · Mar 2025

70.9

Google's 2025 workhorse flagship — first mainstream thinking model with a 1M context, still widely deployed.

The verdict

Gemini 2.5 Pro wins 4 of the 4 benchmarks these models share, against 0 for DeepSeek R1 (0528). On price the gap is dramatic: DeepSeek R1 (0528) works out roughly 3.6x cheaper per blended million tokens. Gemini 2.5 Pro also takes 1.0M 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.
