DeepSeek V4 vs GPT-4o

Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.

DeepSeek V4

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.

GPT-4o

OpenAI · May 2024

The 2024 omni-modal classic with native audio in and out; superseded at the frontier but still everywhere in production.

The verdict

DeepSeek V4 wins 1 of the 1 benchmarks these models share, against 0 for GPT-4o. On price the gap is dramatic: DeepSeek V4 works out roughly 13x cheaper per blended million tokens. DeepSeek V4 also takes 1M of context versus 128K for GPT-4o. And DeepSeek V4 is open-weights (MIT), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
