Ingests documents from diverse sources (files, web, cloud APIs) through a modular reader architecture that abstracts source-specific logic. Each reader implements a common interface that normalizes heterogeneous data formats (PDF, markdown, HTML, JSON, databases) into a unified Document object with metadata preservation. The framework uses a registry pattern to discover and instantiate readers, enabling extensibility without core framework changes.
Unique: Uses a registry-based reader pattern with automatic format detection and metadata preservation, supporting 30+ built-in readers across files, web, and cloud sources without requiring custom code for common integrations. Implements lazy loading for large documents to reduce memory overhead.
vs alternatives: Broader out-of-the-box reader coverage than LangChain's document loaders, with unified metadata handling across all sources and automatic format detection reducing boilerplate.
Splits documents into chunks using multiple strategies (fixed-size, recursive, semantic) that preserve document structure and relationships. The NodeParser abstraction allows pluggable chunking logic; implementations include SimpleNodeParser (basic splitting), HierarchicalNodeParser (preserves heading hierarchy), and SemanticSplitter (uses embeddings to find natural boundaries). Chunk metadata includes parent-child relationships, document source, and custom attributes for context-aware retrieval.
Unique: Implements multiple chunking strategies (simple, recursive, semantic, hierarchical) with automatic parent-child relationship tracking, enabling retrieval systems to fetch full context by traversing node relationships. SemanticSplitter uses embedding-based boundary detection rather than token counting.
vs alternatives: More sophisticated than LangChain's text splitters by preserving document hierarchy and supporting semantic boundaries; enables context-aware retrieval that recovers full sections rather than isolated chunks.
Provides utilities for fine-tuning LLMs on domain-specific data generated from RAG systems. The framework can generate synthetic training data from retrieval results, format it for fine-tuning APIs (OpenAI, Anthropic), and manage fine-tuning jobs. Fine-tuned models can be used as drop-in replacements in RAG pipelines, improving performance on domain-specific tasks without retraining from scratch. The system tracks fine-tuning experiments and enables comparison of base vs fine-tuned model performance.
Unique: Integrates fine-tuning into RAG workflow by generating training data from retrieval results and managing fine-tuning jobs across providers. Enables A/B testing of base vs fine-tuned models without pipeline changes.
vs alternatives: Tightly integrated with RAG pipeline for automatic training data generation; supports multiple fine-tuning providers with unified interface. Enables rapid experimentation with fine-tuned models.
Enables LLMs to generate structured outputs (JSON, Pydantic models, dataclasses) with schema validation. The framework uses provider-specific structured output APIs (OpenAI JSON mode, Anthropic structured output) or LLM-based parsing with validation fallback. Output schemas are defined as Pydantic models or JSON schemas; the framework automatically formats prompts to guide LLM generation and validates outputs against schemas. Failed validations trigger retries with corrected prompts.
Unique: Leverages provider-specific structured output APIs (OpenAI JSON mode, Anthropic structured output) with fallback to LLM-based parsing and validation. Automatically formats prompts to guide generation and retries on validation failure.
vs alternatives: Uses native provider APIs for structured output when available, reducing latency and cost vs LLM-based parsing. Unified interface across providers despite different native APIs.
Integrates with the Model Context Protocol (MCP) standard for tool definition and execution, enabling standardized tool calling across applications. MCP servers expose tools through a standard interface; the framework discovers and registers MCP tools for use in agents and workflows. This enables reuse of tools across different LLM applications and providers without reimplementation. MCP integration handles authentication, request/response serialization, and error handling transparently.
Unique: Integrates Model Context Protocol (MCP) for standardized tool definition and execution, enabling tool reuse across applications and providers. Handles MCP server discovery, authentication, and error handling transparently.
vs alternatives: Enables tool standardization through MCP protocol, reducing tool reimplementation across applications. Supports both local and remote MCP servers.
Manages LLM context windows by tracking token usage and automatically summarizing or truncating context when approaching limits. The framework estimates token counts for prompts, retrieved context, and conversation history using provider-specific tokenizers. When context approaches the model's limit, it applies strategies: summarization (condense context with LLM), truncation (remove oldest messages), or hierarchical retrieval (fetch higher-level summaries). This enables long conversations and large document sets without hitting context limits.
Unique: Automatically manages context windows by tracking token usage and applying strategies (summarization, truncation, hierarchical retrieval) when approaching limits. Uses provider-specific tokenizers for accurate token counting.
vs alternatives: Proactive context management prevents token overflow errors and enables long conversations. Automatic summarization preserves conversation continuity better than simple truncation.
Provides LlamaDatasets and evaluation utilities for benchmarking RAG systems. Datasets include pre-built question-answer pairs for common domains (finance, medical, legal). The framework supports custom dataset creation from documents, automatic evaluation metrics (BLEU, ROUGE, semantic similarity), and comparison of different RAG configurations. Evaluation results are tracked and can be exported for analysis. This enables systematic optimization of RAG pipelines.
Unique: Provides pre-built LlamaDatasets for common domains and utilities for creating custom evaluation datasets. Supports multiple evaluation metrics and systematic comparison of RAG configurations.
vs alternatives: Purpose-built for RAG evaluation with pre-built datasets and metrics; more comprehensive than generic benchmarking tools for RAG-specific use cases.
Provides multiple index types (VectorStoreIndex, SummaryIndex, TreeIndex, PropertyGraphIndex, KeywordTableIndex) that organize ingested nodes for different retrieval patterns. Each index implements a common Index interface with a query_engine() method that returns a QueryEngine for executing retrieval. Indices are backed by pluggable storage (vector stores, graph databases, in-memory) and support hybrid retrieval combining multiple strategies. The framework handles index construction, persistence, and updates transparently.
Unique: Supports 5+ index types with pluggable backends and a unified QueryEngine abstraction, enabling seamless switching between retrieval strategies (semantic, keyword, graph traversal, summarization) without rewriting application code. Implements automatic index persistence and lazy loading.
vs alternatives: More flexible than LangChain's VectorStore abstraction by supporting multiple index types (graph, keyword, summary) with unified query interface; enables hybrid retrieval combining multiple strategies in a single query.
+7 more capabilities
Enables evaluation of AI systems' ability to perform chained mathematical operations (addition, subtraction, multiplication, division, comparisons) across both structured tables and unstructured text extracted from SEC filings. The dataset provides ground-truth question-answer pairs where answers require synthesizing data from multiple locations within earnings reports and applying sequential arithmetic operations, testing whether models can decompose complex financial queries into discrete computational steps.
Unique: Combines real SEC filing documents (not synthetic) with crowdsourced questions requiring multi-step arithmetic, creating a hybrid dataset that tests both domain knowledge extraction and quantitative reasoning in a single evaluation task. Unlike generic math word problems, answers require locating figures within 10+ page documents first.
vs alternatives: More challenging than DROP or SVAMP because it requires financial domain knowledge AND document retrieval before arithmetic, whereas generic math benchmarks assume figures are already extracted
Assesses whether AI systems understand financial terminology, accounting concepts, and domain-specific metrics by requiring them to answer questions about real earnings reports from S&P 500 companies. The dataset tests recognition of financial line items (revenue, COGS, operating expenses, net income), ability to distinguish between different financial statements (income statement vs balance sheet), and understanding of financial ratios and metrics without explicit instruction on their definitions.
Unique: Uses authentic SEC filings rather than synthetic financial data, exposing models to real-world accounting variations, footnote complexity, and the actual structure of professional financial documents. This tests transfer learning from general text to specialized domain without domain-specific pretraining.
vs alternatives: More authentic than synthetic financial QA datasets because it uses real earnings reports with their inherent complexity, but narrower than general financial knowledge benchmarks because it focuses only on historical data interpretation
FinQA scores higher at 60/100 vs llama-index-core at 27/100. llama-index-core leads on ecosystem, while FinQA is stronger on adoption and quality.

Enables evaluation of AI systems' ability to extract numerical data from both structured HTML/text tables and unstructured prose within the same document, then reason over the extracted values. The dataset contains questions where relevant data appears in different formats — some figures are in formatted tables with clear row/column headers, while others are embedded in narrative text or footnotes — requiring robust parsing and entity linking before computation can occur.
Unique: Combines structured table data with unstructured narrative in the same evaluation, forcing systems to handle format heterogeneity and resolve references across different data representations. Most table QA datasets use clean, isolated tables; this tests real-world document complexity.
vs alternatives: More realistic than isolated table QA benchmarks (like SQA or WikiTableQuestions) because it requires handling narrative context and format mixing, but simpler than full document understanding because tables are already in text format (no OCR needed)
Provides a curated, crowdsourced-annotated dataset of 8,281 question-answer pairs with multi-step reasoning requirements, enabling systematic evaluation of AI systems on financial numerical reasoning. The dataset includes quality control mechanisms through crowdworker annotation, answer validation against ground truth, and coverage across diverse financial metrics and company types within the S&P 500, creating a reproducible evaluation standard for the financial AI community.
Unique: Provides a publicly available, reproducible benchmark specifically designed for financial numerical reasoning with real SEC filings, enabling standardized comparison across different financial AI systems. Most financial datasets are proprietary or synthetic; this is open-source and authentic.
vs alternatives: More specialized and challenging than generic QA benchmarks (SQuAD, MRQA) because it requires financial domain knowledge and multi-step arithmetic, but narrower in scope than comprehensive financial understanding benchmarks because it focuses only on numerical reasoning
Assesses AI systems' ability to perform multi-hop reasoning by requiring them to locate and combine information from different sections of earnings reports. Questions may require finding a figure in the income statement, then locating a related metric in the balance sheet, then performing arithmetic across both — testing whether models can maintain context across document boundaries and understand relationships between different financial statement sections.
Unique: Embeds multi-hop reasoning requirements within authentic financial documents where hops correspond to real relationships between financial statement sections, rather than synthetic reasoning chains. This tests whether models understand domain structure, not just generic multi-hop patterns.
vs alternatives: More realistic than synthetic multi-hop datasets (HotpotQA, 2WikiMultiHopQA) because reasoning hops follow actual financial relationships, but less controlled because document structure varies and reasoning paths are implicit rather than explicitly annotated
Enables evaluation of whether AI systems can identify which arithmetic operations (addition, subtraction, multiplication, division, comparison) are required to answer financial questions, then execute them correctly. The dataset implicitly tests operation selection — a question asking 'what is the profit margin' requires division (net income / revenue), while 'what is total assets' requires addition — forcing models to understand financial semantics before applying math.
Unique: Embeds arithmetic operation selection within financial domain context, requiring models to understand that 'margin' semantically maps to division and 'total' maps to addition. This tests semantic grounding of operations, not just arithmetic execution.
vs alternatives: More semantically grounded than generic math word problem datasets because operation selection is implicit in financial terminology, but less explicit than datasets with annotated operation types because operations must be inferred
Provides evaluation capability for AI systems to compare financial metrics across multiple S&P 500 companies or aggregate metrics across different time periods within the same company's earnings reports. While individual questions reference single documents, the dataset structure enables evaluation of systems that can retrieve and compare relevant companies, requiring understanding of which metrics are comparable across entities and how to normalize for company size or accounting differences.
Unique: Provides a foundation for evaluating cross-company financial comparison by including diverse S&P 500 companies with different business models and scales, enabling assessment of whether systems can normalize and compare metrics appropriately. Most financial QA datasets focus on single-document questions.
vs alternatives: Enables cross-company evaluation unlike single-document QA datasets, but requires external retrieval and comparison logic because the dataset itself contains only single-document questions
