V4-Flash vs. V4-Pro: DeepSeek promised better and cheaper. It’s true, but not how I expected.

DeepSeek moved its V4-Flash model out of preview and published benchmark claims that it beats V4-Pro on coding and agentic tasks despite a much lower price. V4-Flash is listed at $0.14 per 1M input tokens and $0.28 per 1M output tokens, about one-third of V4-Pro’s $0.435 and $0.87. In side-by-side OpenCode tests on a Rich-codebase suite, Flash and Pro tied on bug-fix and feature tasks, but Flash performed better on a 5,000-row table optimization while Pro stayed cheaper on token volume for a slightly smaller speedup.
