WireByte Staff · July 7, 2026

Kapa, a developer of AI assistants for complex question answering, has introduced a new feature that reduces the amount of context needed for its retrieval API and end-to-end assistants. This 'context pruning' technique cuts the cost of a query by a third while retaining 96% of recall. The company claims this improvement is crucial for handling large and complex knowledge bases.

Key points

  • Kapa, a tech firm developing AI assistants for complex question answering, has introduced context pruning to reduce the amount of context needed for its retrieval API and end-to-end assistants.
  • Context pruning cuts the cost of a query by a third while retaining 96% of recall, according to the company.
  • This improvement is crucial for handling large and complex knowledge bases, which can be costly and time-consuming to process.
  • Kapa's retrieval API and end-to-end assistants will benefit from this enhancement, making them more efficient and cost-effective.

Kapa, a leading developer of AI assistants, has made a significant breakthrough in the field of complex question answering. The company has introduced a new feature called context pruning, which reduces the amount of context needed for its retrieval API and end-to-end assistants. This innovation is crucial for handling large and complex knowledge bases, which can be costly and time-consuming to process.

Context pruning works by using a small, cheap language model to read the question and the retrieved chunks of documentation together. This model then throws out the chunks that the answer will not need before the expensive model ever sees them. As a result, the cost of a query is cut by a third, net of its own cost.

This improvement is a game-changer for Kapa's retrieval API and end-to-end assistants. By reducing the amount of context needed, these tools will become more efficient and cost-effective. This is especially important for developers who use Kapa's retrieval API to give their agents context about their product.

Kapa's context pruning technique is a significant advancement in the field of complex question answering. It demonstrates the company's commitment to innovation and its dedication to providing the best possible solutions for its customers.
