DeepSeek V4 Flash
The efficient V4 variant — 284B MoE, same 1M context, MIT license
Verdict
Same architecture and 1M context as V4 Pro at a fifth of the size (284B total / 13B active) and roughly a fifth of the price ($0.14/$0.28 per million tokens). Give up some ceiling on the hardest reasoning tasks in exchange for materially cheaper, faster inference — the right default for high-volume pipelines that do not need V4 Pro's full capability.
