DeepSeek V3.2 vs GPT-4.1
Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
DeepSeek · Sep 2025
The sparse-attention release that halved DeepSeek's already-lowest-in-class prices while keeping GPT-class quality.
OpenAI · Apr 2025
A non-reasoning workhorse with a 1M-token context window, still popular for predictable-latency production APIs.
The verdict
DeepSeek V3.2 wins 2 of the 2 benchmarks these models share, against 0 for GPT-4.1. On price the gap is dramatic: DeepSeek V3.2 works out roughly 11x cheaper per blended million tokens. GPT-4.1 also takes 1M of context versus 128K for DeepSeek V3.2. And DeepSeek V3.2 is open-weights (MIT), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
