ethical implications

The next generation of Language Model Systems (LLMs) and LLM chatbots are expected to offer improved accuracy, expanded language support, enhanced computational efficiency, and seamless integration with emerging technologies. These advancements indicate a higher level of versatility and practicality compared to the previous models.

While AI solutions do present potential benefits such as increased efficiency and cost reduction, it is crucial for businesses and society to thoroughly consider the ethical and social implications before widespread adoption.

Recent strides in LLMs have been remarkable, and their future appears even more promising. Although we may not be fully prepared, the future is already unfolding, demanding our adaptability to embrace the opportunities it presents.


Back to basics: Understanding large language models

LLM, standing for Large Language Model, represents an advanced language model that undergoes training on an extensive corpus of text data. By employing deep learning techniques, LLMs can comprehend and produce human-like text, making them highly versatile for a range of applications.

These include text completion, language translation, sentiment analysis, and much more. One of the most renowned LLMs is OpenAI’s GPT-3, which has received widespread recognition for its exceptional language generation capabilities.

Challenges in traditional AI chatbot development: Role of LLMs

The current practices for building AI chatbots have limitations when it comes to scalability. Initially, the process involves defining intents, collecting related utterances, and training an NLU model to predict user intents. As the number of intents increases, managing and disambiguating them becomes difficult.

Additionally, designing deterministic conversation flows triggered by detected intents becomes challenging, especially in complex scenarios that require multiple interconnected layers of chat flows and intent understanding. To overcome these challenges, Large Language Models (LLMs) come to the rescue.

Building an efficient LLM application using vector embeddings

Vector embeddings are a type of representation that can be used to capture the meaning of text. They are typically created by training a machine learning model on a large corpus of text. The model learns to associate each word with a vector of numbers. These numbers represent the meaning of the word in relation to other words in the corpus.


LLM chatbots can be built using vector embeddings by first creating a knowledge base of text chunks. Each text chunk should represent a distinct piece of information that can be queried. The text chunks should then be embedded into vectors using a vector embedding model. The resulting vector representations can then be stored in a vector database.

Step 1: Organizing knowledge base

  • Break down your knowledge base into smaller, manageable chunks. Each chunk should represent a distinct piece of information that can be queried.
  • Gather data from various sources, such as Confluence documentation and PDF reports.
  • The chunks should be well-defined and have clear boundaries. This will make it easier to extract the relevant information when querying the knowledge base.
  • The chunks should be stored in a way that makes them easy to access. This could involve using a hierarchical file system or a database.

Step 2: Text into vectors

  • Use an embedding model to convert each chunk of text into a vector representation.
  • The embedding model should be trained on a large corpus of text. This will ensure that the vectors capture the meaning of the text.
  • The vectors should be of a fixed length. This will make it easier to store and query them.



Step 3: Store vector embeddings

  • Save the vector embeddings obtained from the embedding model in a Vector Database.
  • The Vector Database should be able to store and retrieve the vectors efficiently.
  • The Vector Database should also be able to index the vectors so that they can be searched by keyword.

Step 4: Preserve original text

  • Ensure you store the original text that corresponds to each vector embedding.
  • This text will be vital for retrieving relevant information during the querying process.
  • The original text can be stored in a separate database or file system.

Step 5: Embed the question

  • Use the same embedding model to transform the question into a vector representation.
  • The vector representation of the question should be similar to the vector representations of the chunks of text
  • that contains the answer.

Step 6: Perform a query

  • Query the Vector Database using the vector embedding generated from the question.
  • Retrieve the relevant context vectors to aid in answering the query.
  • The context vectors should be those that are most similar to the vector representation of the question.

Step 7: Retrieve similar vectors

  • Conduct an Approximate Nearest Neighbor (ANN) search in the Vector Database to find the most similar vectors to the query embedding.
  • Retrieve the most relevant information from the previously selected context vectors.
  • The ANN search will return a list of vectors that are most similar to the query embedding.
  • The most relevant information from these vectors can then be used to answer the question.

Step 8: Map vectors to text chunks

  • Associate the retrieved vectors with their corresponding text chunks to link numerical representations to actual content.
  • This will allow the LLM to access the original text that corresponds to the vector representations.
  • The mapping between vectors and text chunks can be stored in a separate database or file system.

Step 9: Generate the answer

  • Pass the question and retrieved-context text chunks to the Large Language Model (LLM) via a prompt.
  • Instruct the LLM to use only the provided context for generating the answer, ensuring prompt engineering aligns with expected boundaries.
  • The LLM will use the question and context text chunks to generate an answer.
  • The answer will be in natural language and will be relevant to the question.

Building AI chatbots to address real challenges

We are actively exploring the AI chatbot landscape to help businesses tackle their past challenges with conversational automation.

Certain fundamental aspects of chatbot building are unlikely to change, even as AI-powered chatbot solutions become more prevalent. These aspects include:

  • Designing task-specific conversational experiences: Regardless of where a customer stands in their journey, businesses must focus on creating tailored experiences for end users. AI-powered chatbots do not eliminate the need to design seamless experiences that alleviate pain points and successfully acquire, nurture, and retain customers.
  • Optimizing chatbot flows based on user behavior: AI chatbots continually improve their intelligence over time, attracting considerable interest in the market. Nevertheless, companies still need to analyze the bot’s performance and optimize parts of the flow where conversion rates may drop, based on user interactions. This holds true whether the chatbot utilizes AI or not.
  • Integrating seamlessly with third-party platforms: The development of AI chatbot solutions does not negate the necessity for easy integration with third-party platforms. Regardless of the data captured by the bot, it is crucial to handle and utilize that information effectively in the tech stacks or customer relationship management (CRM) systems used by the teams. Seamless integration remains essential.
  • Providing chatbot assistance on different channels: AI-powered chatbots can and should be deployed across various channels that customers use, such as WhatsApp, websites, Messenger, and more. The use of AI does not undermine the fundamental requirement of meeting customers where they are and engaging them through friendly conversations.
