Large Language Models

What are Large Language Models (LLMs)?

A large language model is trained to generate natural language text in response to input prompts, built on neural network architectures capable of learning complex patterns in massive amounts of training data. Unlike older, rule-based NLP models that require extensive domain-specific programming, LLMs generate language based on patterns learned from broad, largely unstructured data, which is part of why they scale across domains and languages more easily.

Common LLM Applications

• Sentiment analysis: detecting the emotional tone behind a piece of text, positive, negative, or neutral.
• Named entity recognition: identifying and classifying specific information, like a product, account, or date, within unstructured text.
• Translation: converting text between languages while preserving meaning and context.
• Content generation: drafting responses, summaries, or other text based on a prompt rather than a fixed template.
• Text classification: sorting text into categories, such as routing a customer message to the right department based on its content.

How Contact Centers Use LLMs

LLMs power AI conversation simulation for training (Zenarate Perform), where the model plays a realistic, responsive customer persona; real-time coaching feedback (Zenarate Analyze), where it can summarize a call or explain why it scored the way it did; and AI agents (Zenarate Evolve), capable of handling a full customer conversation.

Managing Bias and Accuracy

LLMs can inadvertently learn and reproduce biases present in their training data, which is why developers need to carefully curate training data and evaluate outputs across multiple scenarios. In a contact center context, this is also why grounding an LLM's responses in your specific, current policies (see Retrieval-Augmented Generation) matters more than which underlying model a vendor uses.

Frequently Asked Questions

Does it matter which LLM a contact center vendor uses?

Less than you'd expect. How well it's grounded in your specific policies and tested for your use case typically matters more than which base model it's built on.

Are LLMs the same as generative AI?

LLMs are a specific type of generative AI focused on language; generative AI is the broader category that also includes image, audio, and video generation.

Can LLMs be used for compliance-sensitive contact center conversations?

Yes, but they need to be grounded in accurate, current policy information and paired with human oversight and QA scoring.
