# Speculative Decoding

An optimization technique where a small, fast model predicts the next few tokens, and a larger model only verifies them, drastically increasing speed.

## Business Value

Reduces latency for real-time AI applications by up to 3x without sacrificing the accuracy of high-end models.

## Context Studios Perspective

User experience is non-negotiable. We use speculative decoding to make complex enterprise agents feel as fast as a simple search query.
