What Are AI Agents?

Intro

When it comes to scaling customer service, businesses are facing more challenges than ever before. Customer demand is higher, their needs are more complex, and they expect businesses to offer omnichannel service at a time that suits them.

How can a scaling enterprise meet these challenges without soaring costs?

Meet the AI Agent – an automated customer service representative that can transform your customer service processes to supercharge productivity, cut waiting times, speed up call resolutions and slash costs.

In this guide, we’ll explore how Artificial Intelligence gives enterprise organizations an incredible tool to drive fast, efficient contact center automation at scale.

Key Takeaways

What Is an AI Agent?

An AI Agent is a digital assistant that uses Artificial Intelligence to engage with real customers in a way that mimics human interaction. AI Agents are available 24/7 and have no downtime, allowing you to offer instant customer service that cuts down on waiting times, speeds up call resolutions, and improves customer satisfaction.

Where earlier iterations of automated customer support tools (such as ‘chatbots’) were strictly limited to specific pre-planned scenarios, AI Agents are flexible and fluid autonomous systems that can understand human language, call on short and long-term memories, and even reason through problems.

Perhaps most importantly, an AI Virtual Agent is also action-orientated. It is integrated with your backend systems and tools and can recognize goals within a customer’s query, create tasks, and then carry them out – all without human intervention.

How Does an AI Agent Work?

AI Agents combine different types of Artificial Intelligence (AI), such as:

  1. Conversational AI: Allows a machine to understand human language via both voice or text input and communicate in a human-like manner.
  2. Generative AI: Generates content in response to user prompts and input.
  3. Agentic AI: Allows an AI to reason its way through problems dynamically, plan its own goal-orientated workflow, and pursue its own objectives.

AI Agents understand and interpret user input to identify goals and carry out actions. They are trained using Large Language Models (LLMs) to build a deep knowledge of language, then fine-tuned using industry-specific databases and knowledge hubs. With this knowledge, an AI Agent can be deployed to tackle customer support problems immediately – but it will continue to learn and improve as it works.

The most compelling feature of an AI Agent is its ability to engage in progressive reasoning. This refers to the process of interpreting user intent based on contextual clues, identifying needs, and then breaking them down into goals, which the agent can then pursue as efficiently as possible.

Benefits of AI Agents

There are many different benefits associated with the type of automation an autonomous AI Agent provides to your business. By improving your organization's cost and time savings and providing better, personalized customer interactions, an autonomous AI Agent increases performance both internally and externally.

Improved Efficiency

An AI Agent's primary benefit is improving efficiency across your customer service processes. It can achieve this either by engaging directly in customer-facing support and cutting down on long wait times and call lengths – but also by assisting human agents via Agent Copilot features.

Enhanced Customer Experience

Customers have clear expectations when it comes to approaching customer service teams – they want fast, efficient support that feels personalized around their needs. AI Agents allow you to field queries 24/7 and in a language that best suits your customers, without having to invest in expensive translation teams.

Data-Driven Insights

AI Agents aren’t solely for customer-facing applications. They can also perform large-scale analysis across all of your call history to identify patterns and sentiment. By analyzing vast amounts of data and making recommendations based on your customers' genuine, evidence-based patterns and habits, AI agents provide valuable insights for decision-making.

Personalized Interactions

AI Agents provide this by analyzing a customer’s CRM entry and past interactions using both long-term and short-term memory. This allows the agent to tailor conversations around the customer's needs without asking repeat questions. The agent can also identify any changes in sentiment to adapt on the fly and keep the call focused on positive outcomes.

Cost Savings

The most significant benefit of automation and AI Agents is to drive down costs. AI Agents drive significant cost savings throughout your organization by improving efficiency across every area of your business, increasing customer satisfaction, and reducing the resources required to cope with higher demands.

Types of AI Agents

The two main types of AI Agent worth understanding are:

  1. NLU-Driven Conversational AI - These agents are process-orientated or rules-based.
  2. Agentic AI - Capable of dynamic reasoning and contextual understanding.

Use Cases of AI Agents

AI Agents can be deployed in many different ways to address customer service issues, improve business productivity, and automate mundane processes to free up internal resources.

Identification & Verification

AI Agents can fully automate the process of identifying and verifying customers, which can streamline service and significantly reduce waiting times.

Customer Support Agents

AI Agents can engage directly with customers, using a combination of LLMs and NLU to resolve their needs.

Agent Copilot

AI Agents can enhance human customer service teams by assisting them through various tasks and automating repetitive processes.

Outbound Support

AI Agents can pursue outbound calls dynamically for various purposes, providing proactive support for customers.
