- Why isn't the industry freaking out about DeepSeek 4.1 Flash?
A developer blogger says a month of heavy use of DeepSeek 4.1 Flash left him unable to tell it apart from frontier models such as Claude Opus 5.5 in everyday coding, at a fraction of the cost; he sometimes uses Opus for a final code review and has DeepSeek apply the fixes. He also credits a roughly 437x smaller KV cache versus DeepSeek V1 for keeping all-day sessions under a dollar, and dismisses the dispute over Chinese labs allegedly distilling Claude's training data as irrelevant to developers chasing value.
