Converts unstructured documents (PDF, DOCX, TXT, JSON, images) into semantically-indexed text chunks through the Parser class, which applies format-specific extraction logic and stores parsed content via the Library class with configurable chunk sizes and overlap. The parser maintains document structure metadata (page numbers, section hierarchies) enabling source attribution in RAG pipelines.
Unique: Implements format-specific parser classes that preserve document structure metadata (page numbers, section hierarchies, table contexts) during chunking, enabling precise source attribution in RAG outputs. Unlike generic text splitters, llmware's Parser maintains semantic boundaries and document provenance through the Library class integration.
vs alternatives: Preserves document structure and source metadata during parsing, whereas LangChain's generic splitters lose hierarchical context; integrated with llmware's Library for immediate indexing vs separate pipeline steps.
The EmbeddingHandler class generates dense vector representations for text chunks using configurable embedding models (ONNX, local, or API-based), storing vectors in pluggable vector databases (Milvus, Pinecone, Weaviate, local SQLite). Supports both synchronous batch embedding and asynchronous processing for large-scale document collections.
Unique: Abstracts embedding backend selection through a unified EmbeddingHandler interface supporting ONNX local models, API-based providers, and custom embedders, with automatic vector database persistence. Enables cost-optimized local embedding workflows without vendor lock-in, unlike frameworks that default to cloud APIs.
vs alternatives: Supports local ONNX embeddings for cost and privacy vs LangChain's default cloud-only approach; pluggable vector DB backends reduce migration friction compared to single-backend solutions like Pinecone-only stacks.
llmware provides built-in evaluation utilities for measuring RAG quality through metrics like retrieval precision/recall, answer relevance, and source attribution accuracy. The framework logs prompt-response pairs with metadata (model, tokens, latency, sources), enabling post-hoc evaluation and fine-tuning.

Unique: Integrates Whisper.cpp for local audio transcription with automatic indexing into the document library, enabling RAG over audio content without cloud APIs. Supports multiple audio formats and language detection, extending RAG capabilities beyond text documents.
vs alternatives: Local transcription via Whisper.cpp avoids cloud API costs and privacy concerns vs cloud services (Google Cloud Speech, AWS Transcribe); automatic library indexing enables unified multimodal RAG vs separate transcription and indexing pipelines.
The Query class implements semantic search via vector similarity and hybrid retrieval combining vector and keyword matching against indexed document chunks. Supports query expansion techniques (synonym injection, multi-hop reasoning) to improve recall on ambiguous or complex queries. Retrieval results include relevance scores, source metadata, and chunk context enabling downstream ranking and reranking.
Unique: Implements query expansion at retrieval time using small specialized models (SLIM models) to inject synonyms and related concepts, improving recall without expensive reranking. Hybrid retrieval combines vector similarity with keyword matching through configurable alpha weighting, enabling both semantic and exact-match queries in a single call.
vs alternatives: Built-in query expansion via SLIM models improves recall vs static vector-only retrieval; hybrid approach handles both semantic and keyword queries vs pure vector solutions like Pinecone; integrated with llmware's small model ecosystem for on-device expansion.
The ModelCatalog class provides unified access to 150+ models including proprietary APIs (OpenAI, Anthropic, Cohere), open-source models (Llama, Mistral, Falcon), and llmware's specialized small models (BLING, DRAGON, SLIM).
