DeepSeek V4 Flash (Max) makes more sense if you want the cheaper token bill, while DeepSeek V4 Pro (Max) is the cleaner fit if agentic is the priority.
DeepSeek V4 Flash (Max) and DeepSeek V4 Pro (Max) sit in the same DeepSeek V4 family. This page is less about two unrelated model lineages and more about how the siblings trade off on benchmark shape, token costs, and practical limits like context window.
DeepSeek V4 Pro (Max) is clearly ahead on the provisional aggregate, 87 to 77. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
DeepSeek V4 Pro (Max)'s sharpest advantage is in agentic, where it averages 74 against 63.3. The single biggest benchmark swing on the page is SimpleQA, 34.1% to 57.9%.
DeepSeek V4 Pro (Max) is also the more expensive model on tokens at $1.74 input / $3.48 output per 1M tokens, versus $0.14 input / $0.28 output per 1M tokens for DeepSeek V4 Flash (Max). That is roughly 12.4x on output cost alone.
DeepSeek V4 Flash (Max) and DeepSeek V4 Pro (Max) are sibling variants in the DeepSeek V4 family, so the right pick depends on whether you value the better benchmark line, cheaper tokens, or the larger context window. DeepSeek V4 Pro (Max) is ahead on BenchLM's provisional leaderboard 87 to 77.
DeepSeek V4 Pro (Max) has the edge for knowledge tasks in this comparison, averaging 66.1 versus 60. Inside this category, SimpleQA is the benchmark that creates the most daylight between them.
DeepSeek V4 Pro (Max) has the edge for coding in this comparison, averaging 75.9 versus 73.7. Inside this category, Codeforces is the benchmark that creates the most daylight between them.
DeepSeek V4 Pro (Max) has the edge for agentic tasks in this comparison, averaging 74 versus 63.3. Inside this category, GDPval-AA is the benchmark that creates the most daylight between them.
