What’s inside

  • A cost-aware router sends each document to the cheapest extraction tier that still clears the quality bar.
  • Retrieval runs on Amazon OpenSearch as a lexical-first hybrid index. No vector database to operate.
  • AskNeedl reached 64.66% accuracy on OfficeQA Pro, ahead of every published agent baseline, at a fifth of the cost.
