## Details

## Overview

Sycamore is an LLM-powered search and analytics platform for unstructured data that combines advanced document processing, semantic understanding, and scalable data transformation into a unified framework.

## Core Concept: DocSet Abstraction

Sycamore provides a declarative dataflow abstraction called a **DocSet** for manipulating unstructured documents:
- Similar in style to Apache Spark and Pandas
- Designed specifically for collections of unstructured documents
- Enables scalable, distributed document processing
- Supports complex transformation pipelines

## Document Processing Capabilities

### Supported Document Types
- Reports and presentations
- Transcripts and meeting notes
- Technical manuals
- PDFs with embedded content
- Images and scanned documents
- Documents with tables, figures, and graphs

### Processing Features
- **Intelligent Partitioning**: Breaks documents into logical sections
- **Content Enrichment**: Adds metadata and structure using LLMs
- **Complex Element Handling**: Tables, figures, graphs, and infographics
- **Multi-modal Understanding**: Text, images, and structured data

## LLM Integration

### Flexible Model Support
- Choose your preferred LLM provider
- Support for OpenAI, Anthropic, and other APIs
- Local model deployment options
- Cost-optimized model selection

### LLM-Powered Transforms
- Information extraction
