What is LLM Agent and how to build them

Customers demand seamless interactions, personalized services, and instant resolutions. Imagine having a virtual assistant so intuitive and empathetic that it reduces human intervention and work round the clock without breaks.

Meet LLM Agent – a revolutionary language model-driven AI that's transforming customer experiences. In this blog, discover how you can harness the power of these intelligent bots to take your CX strategy to unprecedented heights. 

What is an LLM Agent? 

Large language model, such as GPT-3 (Generative Pre-trained Transformer), is kind of Artificial Intelligence(AI) model designed to mimic human-like conversational behavior, providing intelligent and contextually relevant responses to a wide range of queries or prompts. They aim to facilitate seamless communication between humans and machines, offering personalized assistance and information based on user prompts. 

LLM Prompts

LLM prompts are the inputs or queries provided by users to an LLM agent to generate responses. These prompts are crucial for the machine to understand and answer user queries accurately. 

LLM agents can adapt to various industries, helping businesses achieve maximum potential in less time and reducing manual work. But, there are limitations to LLM. LangChain framework and Chain of Thought Prompting fill that essential gap.  

Let’s understand what are they and how they impact the performance of LLM Agents. 

What is LangChain Agent?

While LLMs possess broad capabilities that enable them to handle numerous tasks, there are limitations when it comes to providing in-depth domain expertise. For instance, when you ask the LLM agent about a field like security or marketing it can answer your basic queries but fails to generate responses with deeper knowledge or expertise. 

LangChain agent uses an approach where the corpus of text is preprocessed by cutting it down into small pieces or summaries, embedding them in a vector space, and searching for similar pieces when a query is posted. LangChain provides an abstraction that simplifies the process of composing these pieces and thus helps users like you and me in gaining deeper domain knowledge. 

Chain of Thought Prompting 

Large Language Models have a limitation in reasoning ability too, to overcome this limitation, a chain of thought, a series of intermediate natural language reasoning steps are to be included, in the few-shot prompting process. 

"Chain-of-Thought Prompting Elicits Reasoning in Large Language Models" a research paper authored by Google Research, Brain Team introduces a new approach called chain-of-thought prompting, which improves the reasoning abilities of LLMs such as GPT-4. This approach adds intermediate natural language reasoning steps to few-shot prompts, enabling the model to break down complex tasks into smaller steps. 

Chain of thought prompting is used in cases for arithmetic reasoning, common sense reasoning, and symbolic reasoning this in turn improves the interoperability and problem-solving capabilities of LLMs. 

Now let’s get our hands dirty and practically understand how to implement LLM that elevates your customer experience.


Step-by-step process to implement LLM Agent

Data Collection:

Gather a large and diverse dataset of text that is relevant to the domain you want the LLM agent to specialize in. This dataset will be used to train the language model.

Preprocessing Data:

Clean and preprocess the collected text data by removing noise, formatting inconsistencies, and irrelevant information. Tokenize the text into smaller units to facilitate model training. 

Training the Language Model:

Utilize ML techniques, particularly NLP approaches, to train the language model using the preprocessed dataset. Deep learning architectures like Transformer models have proven to be effective for training LLM agents. Training involves feeding the language model with sequences of text and optimizing its parameters to learn the statistical patterns and relationships within the data. 


Fine-tune the pre-trained language model on a more specific task or domain to enhance its performance and adapt it to your desired use case. This involves training the model on a task-specific dataset while keeping the pre-learned knowledge intact. 

Evaluation and Iteration:

Evaluate the performance of the LLM agent using appropriate metrics, such as perplexity or accuracy, and refine the model as needed. Iterate through the training and fine-tuning process to continuously improve the agent's capabilities. 

Deployment and Integration:

Once the LLM agent has reached satisfactory performance, deploy it in a production environment or integrate it into your desired application or platform. Provide the necessary APIs or interfaces for interaction with the agent. 

Continuous Learning and Improvement:

Enable the LLM agent to learn and adapt to new data by periodically updating and retraining it with the latest information. This ensures that the agent stays up-to-date and maintains its relevancy over time. 

Introduction to LLM Conversational Agents 

An LLM-powered conversational agent is a chatbot that is powered by a large language model. These types of bots are programmed with Natural Language Processing (NLP), recognize keywords and phrases, understand sentiment from customer interactions and respond with appropriate information. LLM agents are trained on massive amounts of data that enable them to learn the patterns of human language and generate texts with a high level of accuracy and efficiency.  

LLM conversational agents can be used in various industries and to automate services. 

Automation using LLM Agents  

AI-powered LLM conversational agents are now being used in multiple industries and companies are making the most of their services through automation.

Customer Service:

LLM agents can provide personalized experiences by analyzing customers’ past interactions and purchase preferences. LLM Agent uses this information to provide solutions and product recommendations. It can also be used to automate the generation of issue tickets and provide customer support in many ways.  

This can free up human customer support agents to focus on more complex tasks, while also ensuring that customers receive accurate and timely support.

Sales and Marketing:

With LLM agents you can generate personalized sales and marketing materials, such as emails, landing pages, and social media posts. This can help businesses to reach a wider audience and improve their conversion rates faster.  

Content Creation:

LLM-powered conversational agents generate text, such as emails, reports, or marketing materials. This generated content is tailored to specific audiences and purposes, ensuring that it is both informative and engaging. 


Provide answers to users with accurate and up-to-date information. 

Analyzing and Reporting:

AI Agents can analyze data, and identify patterns and trends that would be difficult or time-consuming for humans to find; with this automated service, businesses can make better decisions. 

Translate languages:

Translate in multiple other languages, allowing businesses to reach a wider audience and save costs involved in translation.

Generating code:

Generate code to automate tasks or create new applications. 

As LLM agents become more powerful and accessible to small and big enterprises, we can see more use cases in the future.
