What reuse looks like here.
Pricing, context, and capabilities for DeepSeek-V4-Flash are live, but it is outside the flagship set Zumik benchmarks in depth, so measured reuse, capture, and warm TTFT are not shown yet. Run a workload estimate or route it by id to start collecting traces.
What you actually pay once caching works.
At a typical 55% prefix reuse, a million input tokens on DeepSeek-V4-Flash effectively costs $0.08 instead of $0.14 - blending to roughly $0.13 with a 25% output share. There is no batch tier, so cost control here leans on caching and routing.
Estimate it for your workloadRoute it directly by id, or let an alias pick it when it wins under policy.
