Measured by Zumik

What reuse looks like here.

Not yet profiled

Pricing, context, and capabilities for Gemini 2.5 Pro 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.

Reuse economics

What you actually pay once caching works.

At a typical 55% prefix reuse, a million input tokens on Gemini 2.5 Pro effectively costs $0.63 instead of $1.25 - blending to roughly $2.97 with a 25% output share. Background work drops a further 50% on the batch tier.
