Introduction: Welcome back to Dev Explaining! In this video, we will discuss how to chat with your own documents using Open AI API, Lang Chain, and GPT-3. We will explore the process of fetching and organizing your documents, creating a vector store, embedding your knowledge base, and utilizing the power of Lang Chain and the GPT-3 model. We will also discuss the pros and cons of using the Open AI API and introduce the concept of GPT for all. So let's dive into the exciting world of chatbot development!

Using the Open AI API: To utilize the Open AI API, we begin by fetching and organizing our documents. In this case, we will use a company blog as our source material. We need to extract the text content from the blog articles and remove any formatting. This can be done using Python tools such as Beautiful Soup. By navigating through the blog's pages and grabbing the content, we can create a text file that will serve as the basis for our knowledge base.

Fetching and Organizing Documents: After obtaining the text content from our documents, we need to organize them in a way that allows for efficient searching. This can be done by creating a vector store, which is a type of database that indexes the content based on the similarity of words. We can use Python libraries such as Languascope and DuckDB to generate indexes and store the documents in the vector database. This process allows for rapid queries based on the similarity of words.

Creating a Vector Store: The vector store plays a crucial role in retrieving relevant information from our knowledge base. It allows us to quickly find and extract the most meaningful parts of our documents. By indexing the content based on the similarity of words, we can efficiently search for specific information. There are different types of vector stores available, such as transient (in-memory) and persistent (on-disk). The choice depends on the size of your data and the need for scalability.

Embedding Custom Knowledge Base: To enhance the capabilities of the Open AI API, we can embed our custom knowledge base into the queries. By providing context and relevant information from our documents, we can improve the accuracy of the responses. This can be done through prompts and templates, where we specify the context to be used in answering questions. By combining the power of Lang Chain and the GPT-3 model, we can obtain more relevant and tailored answers.

Using Lang Chain and the GPT Model: Lang Chain is a powerful tool that acts as the glue between different components. It simplifies complex tasks and allows us to perform advanced actions in a straightforward manner. By combining Lang Chain with the GPT-3 model, we can prompt the model to provide answers based on our custom knowledge base. The temperature value can be adjusted to control the level of creativity in the responses.

Pros and Cons of Open AI API: Using the Open AI API comes with both advantages and disadvantages. On the positive side, it provides access to powerful language models and allows for complex interactions. It is relatively easy to use and offers a range of options for customization. However, using the API may incur costs, especially when the free credits are exhausted. Additionally, the API is still evolving, and the pricing structure may change in the future.

Using GPT for All: GPT for all is another option that allows for offline usage of the GPT model. It provides more control over your data and eliminates the need for API access. However, it requires additional setup and configuration. GPT for all is still a work in progress, and the process of combining it with other tools like Lang Chain may require some troubleshooting.

Conclusion: In conclusion, utilizing chatbots with custom knowledge bases can be a powerful tool for information retrieval and interaction. The combination of Open AI API, Lang Chain, and GPT-3 model offers exciting possibilities for building intelligent chatbots. However, it is important to consider the pros and cons of using the API and explore alternative options like GPT for all. Investing time and effort in understanding these technologies can provide significant value in the field of chatbot development.
