antirez questions DeepSeek 4: DS4 PRO shares Flash's architecture but never delivered
antirez · x · 2026-09-10
antirez shares doubts about the DeepSeek 4 story: DS4 PRO uses the same architecture as DeepSeek Flash, which is known to work very well, but at a much larger scale — and in theory it should have delivered quite impressive performance, yet it never really did. "A mystery," he says.
In a follow-up reply, he notes that some benchmarks look terrific in areas like cybersecurity (a huge use case), while others align more with past performance — so he'd wait for testing from the broader user base before trusting the best benchmarks as a general proxy for capability.
