What are LLMs?

Large Language Models (LLMs) are advanced AI systems designed to understand and generate human-like text. They leverage deep learning techniques and vast amounts of data to perform a variety of language-related tasks. LLMs operate on billions of parameters, allowing them to recognize patterns, generate coherent text, and provide contextually relevant responses. For instance, GPT 3.5, GPT 4o, Gemini Pro, Mixtral 8x7b, Claude 3 Haiku, Claude 3.5 Sonnet, Claude 3 Opus are examples of LLMs that use a transformer architecture to process and generate text based on the input it receives.

The role of LLMs extends to numerous practical applications, including PDF data extraction, content generation, customer service, and language translation. They are particularly effective in automated data extraction from PDFs, making them invaluable for businesses that need to extract information from PDFs efficiently.

By using AI PDF data extraction tools powered by LLMs, such as ChatGPT, users can seamlessly pull data from PDFs, and integrate this information into structured formats. This transformation in handling unstructured data has made LLMs a pivotal part of modern technology and data processing.

How Odin AI Uses ChatGPT To Extract Data From PDF

Step 1: Parse PDF

A: Extract text from the PDF

Odin AI uses Optical Character Recognition (OCR) to read and interpret text from images within PDFs, ensuring visual data is included in the analysis.

Tables within PDF documents are accurately read and processed, allowing for precise data extraction from structured formats. This ensures a comprehensive data extraction process.

B: Split the text into proper smaller chunks based on the structure of the document

When a PDF is uploaded to Odin’s knowledge base, it breaks the file into manageable pieces through a sophisticated hybrid semantic chunking mechanism. This involves splitting data at both the sentence and paragraph levels, creating small and large chunks. This ensures that the retrieval process captures the meaning and context of the information, leading to more accurate and relevant responses.

C: Encode those chunks into Embeddings

Each chunk is then encoded into vector embeddings. This involves creating vector representations of data, capturing the meaning and context of unstructured information. This allows Odin to find semantically similar content, improving the accuracy and relevance of search results.

Step 2: Storing the Vector Embeddings in a Vector Database

Odin AI uses advanced vector search technology to enhance its knowledge base capabilities. Vector databases are purpose-built to handle the unique structure of vector embeddings. They index vectors for easy search and retrieval by comparing values and finding those that are most similar to one another, ensuring users can retrieve highly pertinent information even without exact keyword matches.

Step 3: Search Chunk Snippet Relevant to the Input Query

A: Compute embeddings for user’s query

Odin AI computes embeddings for the user’s query using the same technique used to encode the document chunks. This ensures that the query and document embeddings are in the same vector space, allowing for accurate comparison.

B: Search chunk embedding vector from the vector database

Odin AI searches the vector database for the chunk embedding that closely matches the user’s query embeddings. This involves using similarity methods like cosine similarity to find the most relevant chunks.

Step 4: Ask GPT-4o for Answer Based on the Chunk Snippet Provided and User Query

A: Provide 3 inputs

Input1: User query
Input2: The chunk which closely resembled the query
Input3: Some Meta-Instructions if any (e.g., “Answer questions solely based on the information provided in the PDF stored in the Knowledge base”)

B: Odin AI powered by GPT-4o outputs the answer

Odin AI, powered by GPT-4o, processes these inputs and provides an accurate and contextually relevant answer. The dynamic context tracking ensures that responses are personalized and aligned with the ongoing discussion.
