DeepSeek V4 vs Gemini 3.1 Flash-Lite
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.
Google · Mar 2026
The cheapest Gemini 3 model: multimodal input and a 1M context for $0.25/$1.50 — built for massive-scale pipelines.
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. DeepSeek V4 is about 1.6x cheaper per blended million tokens (3:1 input:output mix). And DeepSeek V4 is open-weights (MIT), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
