Crowkis vs AWS Bedrock prompt caching: the cloud's cache serves the cloud
Bedrock's caching cuts repeated-prefix costs inside one cloud's model garden. Your cache strategy deserves a longer horizon than a vendor's feature page.
Bedrock prompt caching follows the provider playbook: repeated prompt prefixes within a short window bill cheaper on supported models. Inside an all-in AWS stack it's a sensible discount to collect. But inventory what it is, input-side, prefix-exact, minutes-lived, model-gated, and bound to one cloud's catalog. Four adjectives and a leash.
The strategic cost is the leash. Build your savings around one cloud's caching semantics and you've added gravity to a decision, model choice, that the last two years have proven you'll revisit quarterly. The best model for your workload keeps changing vendors; a cache that can't follow is a sunk cost waiting to be recognized.

The upgrade is a workflow, not a leap of faith.
Crowkis is deliberately provider-promiscuous: it fronts Bedrock, OpenAI, Anthropic, Gemini, and your local vLLM with the same engine, persists answers durably on your disk, and, at the Enterprise tier, bridges cached answers across providers, so switching models doesn't cold-start your memory. The cache becomes the stable layer in a stack where everything else churns.
The bottom line
Collect every provider discount; they stack with us happily. Just keep the institution's memory in something the institution owns.
