GPT-5.4 wins on more of the categories we score — coding, research, reasoning — so it is the better default of the two. DeepSeek V3 is the better pick when your work is mostly coding and reasoning. Neither is universally "better": GPT-5.4 is aimed at agentic workflows and desktop automation, DeepSeek V3 at coding and reasoning.
DeepSeek V3 is cheaper at $0.27/1M input and $1.1/1M output. GPT-5.4 costs $2.5/1M input and $15/1M output.
GPT-5.4 has the larger context window at 272K tokens vs DeepSeek V3's 128K. For large document analysis, GPT-5.4 is the stronger pick.
GPT-5.4 is better for coding with a score of 90 vs DeepSeek V3's 87 (out of 100). GPT-6 Astra is the overall coding leader in this directory at 100/100.
DeepSeek V3 is faster with a fast speed rating (score: 4) vs GPT-5.4's balanced rating (score: 3). Speed matters most for interactive and high-throughput work; for batch jobs the GPT-5.4 latency penalty is usually invisible.
Claude Opus 4.7 and GPT-5.5 now outperform it on current premium coding benchmarks. Smaller context window (272K) vs Gemini 3.1 Pro (2M) for research. Avoid it if you need the highest current coding benchmark scores — Claude Opus 4.7 and GPT-5.5 are newer premium picks. That is the main case for looking at DeepSeek V3 instead.
Chinese-origin model raises data sovereignty concerns for some enterprise teams. Slightly weaker on nuanced English writing tone compared to Claude and GPT. Less reliable for complex multi-step agentic workflows vs frontier models. Avoid it if your team has data sovereignty requirements or needs enterprise-grade reliability guarantees. Against GPT-5.4 specifically, the gap shows up most on coding (90 vs 87).
Take a moderate workload of 10M input and 2M output tokens a month. DeepSeek V3 runs $4.90 (at $0.27/1M in and $1.1/1M out); GPT-5.4 runs $55.00 (at $2.5/1M in and $15/1M out). That is a $50.10/month difference — DeepSeek V3 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 GPT-5.4 for agentic workflows and desktop automation, with DeepSeek V3 handling coding and reasoning. Routing high-volume, low-stakes calls to DeepSeek V3 at $0.27/1M and reserving GPT-5.4 for the hard cases is usually the cheapest arrangement that does not cost you quality.
