Stop paying twice for the same answer
Most LLM bills are quietly full of duplicates, the same question, reworded, billed at full price every time. Semantic caching is how you stop paying for an answer you already have.
Pull up your model provider's dashboard and squint at the traffic. A shocking share of it is the same handful of questions, asked a hundred different ways. 'How do refunds work?' 'What's the refund window?' 'Refund timeline?' Three prompts, three bills, one answer. Multiply that across a support bot or a fleet of agents and the waste stops being a rounding error.
Without a meaning-aware cache, every rewording is a fresh charge.
Here's the honest math, because we don't like claims you can't reproduce. Crowkis catches essentially all genuine rephrasings, so your savings track how repetitive your traffic is. A workload that's, say, 65% repeated-or-reworded questions sheds roughly that much of its token bill, because those calls never reach the model at all.
Illustrative of a workload where ~65% of traffic is repeated or rephrased. Your number scales with your repeat rate.
And it's fast enough that the cache never becomes the bottleneck. Answering a repeated question from Crowkis takes about thirteen milliseconds for a brand-new phrasing and around four for one it's seen, against a model call that takes a second or two. You're not just saving money; you're handing users an answer roughly a hundred times quicker.
The bottom line
The pitch is embarrassingly simple: don't pay twice. Every question your model has already answered, in any wording, should come back instantly and for free. On repetitive workloads that's a 60-70% cut to your LLM spend, not a projection, a mechanism.
