Generative AI in Customer Service

Last Updated September 28, 2026

Generative AI in customer service uses large language models to understand customer language and create useful responses, summaries and guidance. In the contact center, generative AI can support both customer-facing self-service and employee-facing workflows, but reliable deployment depends on grounding, workflow integration and governance.

Key customer service use cases

• AI virtual agents.
• Real-time agent assist.
• Interaction summaries.
• Knowledge retrieval and answer generation.
• Email and messaging response drafts.
• Conversation analytics and theme summaries.
• Workflow instructions and next-best actions.

Generative AI vs. traditional automation

Grounding is essential

A fluent answer is not necessarily a correct answer. Customer-service AI should retrieve from approved enterprise knowledge and current business data when answering company-specific questions.

Organizations should also define what the model is allowed to infer, what information must come directly from a source system and what requires human review.

Generative AI for agents

Agent assist can summarize customer history, recommend knowledge, draft responses and reduce after-contact work. These capabilities should appear in the agent's normal workflow and should be easy to review or correct.

The goal is to reduce search and administrative effort without removing agent judgment.
