DeepSeek V3 wins on more of the categories we score — coding, research, reasoning — so it is the better default of the two. GPT-5.2 Mini is the better pick when your work is mostly budget technical workflows and high-volume product integrations. Neither is universally "better": DeepSeek V3 is aimed at coding and reasoning, GPT-5.2 Mini at budget technical workflows and high-volume product integrations.
DeepSeek V3 is cheaper at $0.27/1M input and $1.1/1M output. GPT-5.2 Mini costs $1.2/1M input and $4.8/1M output.
Both GPT-5.2 Mini and DeepSeek V3 have the same 128K context window.
DeepSeek V3 is better for coding with a score of 87 vs GPT-5.2 Mini's 78 (out of 100). GPT-6 Astra is the overall coding leader in this directory at 100/100.
Both GPT-5.2 Mini and DeepSeek V3 have similar speed profiles — rated fast. Neither will be the bottleneck if latency is your deciding factor.
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. That is the main case for looking at GPT-5.2 Mini instead.
Weaker on nuanced reasoning than premium models. Gemini 3.1 Flash is now cheaper with a larger context window. Avoid it if cost is your primary concern — Gemini 3.1 Flash offers more for less. Against DeepSeek V3 specifically, the gap shows up most on coding (87 vs 78).
Take a moderate workload of 10M input and 2M output tokens a month. GPT-5.2 Mini runs $21.60 (at $1.2/1M in and $4.8/1M out); DeepSeek V3 runs $4.90 (at $0.27/1M in and $1.1/1M out). That is a $16.70/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 DeepSeek V3 for coding and reasoning, with GPT-5.2 Mini handling budget technical workflows and high-volume product integrations. Since DeepSeek V3 is both the stronger and the cheaper option here, a split mainly makes sense if GPT-5.2 Mini covers a capability you specifically need.
