Why this result
DeepSeek V4 Pro and DeepSeek V4 Pro Base 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 and DeepSeek V4 Pro Base finish on the same BenchAlign overall score, so this is less about a single winner and more about where the edge shows up. The BenchAlign headline says tie; the benchmark table is where the real choice happens.
