DeepSeek-R1 vs GPT-4.1

Side-by-side benchmark comparison across knowledge, coding, math, and reasoning.

DeepSeek-R1 and GPT-4.1 finish on the same overall score, so this is less about a single winner and more about where the edge shows up. The headline says tie; the benchmark table is where the real choice happens.

GPT-4.1 is also the more expensive model on tokens at $2.00 input / $8.00 output per 1M tokens, versus $0.55 input / $2.19 output per 1M tokens for DeepSeek-R1. That is roughly 3.7x on output cost alone. DeepSeek-R1 is the reasoning model in the pair, while GPT-4.1 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. GPT-4.1 gives you the larger context window at 1M, compared with 128K for DeepSeek-R1.

Quick Verdict

Treat this as a split decision. DeepSeek-R1 makes more sense if mathematics is the priority or you want the cheaper token bill; GPT-4.1 is the better fit if knowledge is the priority or you need the larger 1M context window.
