How to cache the OpenAI Node SDK LLM calls with Crowkis

Add a semantic cache to the OpenAI Node SDK so repeated and reworded questions are served for free, no rewrite, self-hosted.

Production LLM traffic is deeply repetitive, and repetition is exactly what a bill is made of. If you build with the OpenAI Node SDK, most of that repetition is invisible in your code but very visible on your bill. A semantic cache in front of your model calls fixes it.

The lowest-friction path is the OpenAI-compatible gateway: point the OpenAI Node SDK's base URL at Crowkis and every model call flows through a semantic cache. Repeated and reworded prompts are served from cache with no upstream call; new ones pass through and get cached.

the OpenAI Node SDK + Crowkis gateway
# point the OpenAI Node SDK at the Crowkis gateway
base_url = "http://127.0.0.1:6380/v1"   # semantic cache in front of your provider
In plain words: You don't restructure your the OpenAI Node SDK app. You change where the calls go, and repeats stop costing money.

On repetitive workloads this cuts LLM costs up to 60-70% on repetitive workloads, and every hit comes back with a confidence score so reuse stays safe. Community edition ships at full power, free to run.
