intermediate Published 12 Jul 2026
Action Steps
  1. Install Python 3.10 or newer to ensure compatibility with the LLM library
  2. Choose an LLM provider like Oxlo.ai for its request-based pricing and OpenAI-compatible SDK
  3. Build a zero-shot text classifier using the LLM library to categorize customer support tickets into categories like Billing, Technical, Account, or General
  4. Test the classifier with sample tickets to evaluate its accuracy and effectiveness
  5. Integrate the classifier into the customer support workflow to automate ticket categorization
Who Needs to Know This

This benefits the customer support team by automating ticket categorization, and the development team by leveraging LLM for text classification without requiring extensive training data or model maintenance. The DevOps team can also utilize this approach for efficient deployment and scaling.
