DeepSeek R1 wins on coding (84 vs 58) and price ($0.55 vs $2.5/1M input). GPT-4o wins on writing quality. For most workflows, DeepSeek R1 is the stronger default — open-source o1-class reasoning at a fraction of the cost.
The safest DeepSeek R1 vs GPT-4o default, the cheaper option worth trying first, and the specialist pick — before you read the detail below.
DeepSeek R1 is the strongest answer here for DeepSeek R1 vs GPT-4o — pick it when quality of output matters more than the $0.55/1M/1M input you pay for it.
GPT-5.1-Codex-Max is the cheaper way in for DeepSeek R1 vs GPT-4o, at $1.25/1M/1M input against DeepSeek R1's $0.55/1M/1M.
GPT-4o is the fastest of these for DeepSeek R1 vs GPT-4o — worth it when latency is what the reader notices, not the last few points of reasoning depth.
DeepSeek R1 leads on coding with a score of 84 vs 58 for GPT-4o.
DeepSeek R1 is cheaper at $0.55/1M input tokens vs $2.5/1M for GPT-4o.
DeepSeek R1 is the stronger default for coding tasks.
Choose DeepSeek R1 for math, science, complex reasoning, and multi-step problem solving at budget cost. Its coding and research scores are what carry the recommendation here.
Choose GPT-4o when your work is mostly multimodal tasks and image-adjacent workflows — that is the workload it was tuned for.
Both models serve different primary workflows — DeepSeek R1 for math and science, GPT-4o for multimodal tasks and image-adjacent workflows — so running each where it has a clear edge often beats forcing one to do both.

DeepSeek R1 wins on more of the categories we score — coding, research, reasoning — so it is the better default of the two. GPT-4o is the better pick when your work is mostly multimodal tasks and image-adjacent workflows. Neither is universally "better": DeepSeek R1 is aimed at math and science, GPT-4o at multimodal tasks and image-adjacent workflows.
DeepSeek R1 is cheaper at $0.55/1M input and $2.19/1M output. GPT-4o costs $2.5/1M input and $10/1M output.
Both DeepSeek R1 and GPT-4o have the same 128K context window.
DeepSeek R1 is better for coding with a score of 84 vs GPT-4o's 58 (out of 100). GPT-6 Astra is the overall coding leader in this directory at 100/100.
GPT-4o is faster with a fast speed rating (score: 4) vs DeepSeek R1's deliberate rating (score: 1). Speed matters most for interactive and high-throughput work; for batch jobs the DeepSeek R1 latency penalty is usually invisible.
Slow — deliberate reasoning takes significantly longer than standard models. Overkill for routine tasks where a faster model gets the same result. Same data sovereignty concerns as DeepSeek V3 for regulated industries. Avoid it if speed matters — R1's deliberate reasoning makes it wrong for interactive or high-throughput use cases. That is the main case for looking at GPT-4o instead.
Outclassed by newer models on pure coding and reasoning. Gemini 3.1 Pro now handles multimodal at a lower price. Avoid it if you need the latest reasoning or coding performance — GPT-5.4 replaces it for serious work. Against DeepSeek R1 specifically, the gap shows up most on coding (84 vs 58).
Take a moderate workload of 10M input and 2M output tokens a month. DeepSeek R1 runs $9.88 (at $0.55/1M in and $2.19/1M out); GPT-4o runs $45.00 (at $2.5/1M in and $10/1M out). That is a $35.12/month difference — DeepSeek R1 is the cheaper of the two at this volume, and the gap scales linearly as you send more. Output tokens dominate the bill on both, so prompt length matters far less than response length.
Yes, and for most teams that beats picking one. A common split is DeepSeek R1 for math and science, with GPT-4o handling multimodal tasks and image-adjacent workflows. Since DeepSeek R1 is both the stronger and the cheaper option here, a split mainly makes sense if GPT-4o covers a capability you specifically need.
