Gemini 2.x Flash cost & gross margin per customer
Gemini Flash is Google's low-latency, low-cost model. Cheap input tokens make it well suited to retrieval-heavy products where you feed in large contexts on a flat price.
Gemini Flash has unusually cheap input ($0.30/Mtok), which makes it ideal for stuffing large contexts — RAG, document analysis — without blowing your margin. Output is moderate, so generation-heavy flows cost more than the input price alone suggests.

- Route easy requests to a cheaper model and reserve Gemini 2.x Flash for the hard ones that actually need it.
- Set a per-customer margin alert so one heavy user can't quietly slip into the red unnoticed.
