DeepSeek R1 (0528)

DeepSeek · May 2025

67.8

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

Gemini 2.5 Flash-Lite

Google · Jul 2025

Ten cents per million input tokens with multimodal support — the price floor of the 2025 Gemini lineup.

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: Gemini 2.5 Flash-Lite works out roughly 5.5x cheaper per blended million tokens. Gemini 2.5 Flash-Lite 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.
