DeepSeek-V4-Flash

DeepSeek-V4-Flash is the high-speed, low-cost edition in the V4 flagship line, pairing strong reasoning with very low invocation cost for high-frequency production use.

It complements V4-Pro within the latest V4 generation: Flash emphasizes throughput and economy where Pro emphasizes peak performance, both under the same low-cost positioning.

DeepSeek-V4-Flash reinforces that high-speed, low-cost tiers can still deliver strong reasoning performance, illustrating that relatively low-cost models can achieve high performance at scale.
