Claude Opus 4.6 wins on more of the categories we score — coding, research, long context — so it is the better default of the two. DeepSeek R1 is the better pick when your work is mostly math and science. Neither is universally "better": Claude Opus 4.6 is aimed at agentic coding and complex multi-step reasoning, DeepSeek R1 at math and science.
DeepSeek R1 is cheaper at $0.55/1M input and $2.19/1M output. Claude Opus 4.6 costs $5/1M input and $25/1M output.
Claude Opus 4.6 has the larger context window at 1M tokens vs DeepSeek R1's 128K. For large document analysis, Claude Opus 4.6 is the stronger pick.
Claude Opus 4.6 is better for coding with a score of 99 vs DeepSeek R1's 84 (out of 100). GPT-6 Astra is the overall coding leader in this directory at 100/100.
Claude Opus 4.6 is faster with a deliberate speed rating (score: 2) 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.
Premium pricing ($15/$75) makes it expensive for high-volume usage. Sonnet 4.6 is only 1.2 points behind on SWE-bench at 5× lower cost. Avoid it if you want the current premium coding leader, need lower cost, or are starting a new integration. That is the main case for looking at DeepSeek R1 instead.
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. Against Claude Opus 4.6 specifically, the gap shows up most on coding (99 vs 84).
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); Claude Opus 4.6 runs $100.00 (at $5/1M in and $25/1M out). That is a $90.12/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 Claude Opus 4.6 for agentic coding and complex multi-step reasoning, with DeepSeek R1 handling math and science. Routing high-volume, low-stakes calls to DeepSeek R1 at $0.55/1M and reserving Claude Opus 4.6 for the hard cases is usually the cheapest arrangement that does not cost you quality.
