Hostinger is a leading provider of web hosting solutions, serving over a million creators from 150+ countries. At Braintrust, we've had the opportunity to work closely with Hostinger as they work on exciting AI applications, like an AI Customer Support chatbot that now handles over 40% of support chat conversations.

In the video below, Liucija (Senior Data Scientist on the AI team @ Hostinger) explains how she approaches AI evaluations.

Hostinger's Approach to Evaluations (0:10)

As Liucija explains in the video, the Hostinger team has 3 main goals when they run LLM evaluations:

  1. Evaluate how offline changes impact application behavior during development, including running evaluations as part of the CI/CD process
  2. Continually assess the performance of live AI applications
  3. Identify and prioritize emerging issues to further improve the application

What Evaluations does Hostinger Run? (1:47)

The Hostinger team runs a variety of evaluations. Some examples include:

  • Component checks (URLs, correct doc)
  • Automated comparison vs. expected answers (factuality, truthfulness)
  • Automated evaluations without expected answers (sentiment analysis, safety)
  • Internal human review (thumbs up/down, comments)
  • Live user feedback (thumbs up/down, comments)

How Braintrust Supports Hostinger (2:40)

After a quick setup process (Liucija got started by herself!), the Hostinger team now leverages Braintrust to run evaluations, track progress using a visual dashboard, drill down into specific improvements / regressions, manage / version datasets, and log production data. Braintrust saves the Hostinger team hours of manual evaluation a day, allowing Hostinger to work on 3x more AI features with high quality assurance.
