HOW WE TAUGHT A SMALL LLM TO THROW AWAY 68% OF OUR RAG CONTEXT

A small, cost-effective LLM was implemented to prune retrieved context chunks for question-answering systems in order to improve efficiency, successfully discarding 68% of unnecessary chunks while maintaining 96% recall. This method addresses the traditional challenge of balancing cost and recall in complex knowledge bases, where irrelevant context can increase expenses without aiding the response accuracy.

I LET REACT COMPILER HANDLE MEMOIZATION: HERE'S WHAT ACTUALLY BROKE

The React compiler automates memoization in applications, allowing code to be simplified by removing manual useMemo and useCallback hooks. The migration process involves establishing lint rules first to catch potential issues, enabling the compiler afterward, and understanding that the DevTools memoization badge does not guarantee successful optimizations.
