Orchestrates the execution of test cases against metrics using the evaluate() function, which handles parallel metric execution, result aggregation, and test run persistence. The execution engine manages metric scheduling, error handling, and result caching. Test runs are tracked with metadata (timestamp, model version, dataset version) and can be compared across iterations to detect regressions.
Unique: Implements a test run orchestration engine that executes metrics in parallel, aggregates results, and persists them to the Confident AI platform with full metadata tracking (model version, dataset version, timestamp). Includes built-in caching to avoid redundant metric evaluations.
vs alternatives: More integrated than running metrics manually and more scalable than sequential evaluation because it handles parallel execution, result aggregation, and persistence in a single abstraction.

Automatically loads and parses documents from diverse sources (PDFs, Word docs, HTML, Markdown, code files, databases) into a unified in-memory representation using format-specific loaders and node-based document abstractions. Each document is decomposed into Document objects containing metadata, content, and relationships, enabling downstream processing without format-specific handling in application code.

Loaders are composable and chainable, allowing sequential transformations (e.g., load → split → extract metadata → embed).
vs alternatives: Broader out-of-the-box loader coverage than LangChain's document loaders and more structured node-based decomposition than raw text splitting, reducing boilerplate for multi-source RAG pipelines.
Splits documents into semantically coherent chunks using multiple strategies (character-based, token-aware, recursive, semantic) with configurable overlap and chunk size. Preserves document hierarchy and metadata through a node tree structure, enabling retrieval systems to maintain context relationships and enable hierarchical re-ranking or parent-document retrieval patterns.

vs alternatives: More sophisticated than LangChain's text splitters because it preserves hierarchical relationships and supports semantic splitting; better for complex document structures than simple character-based splitting.
LlamaIndex scores higher at 40/100 vs deepeval at 24/100. However, deepeval offers a free tier which may be better for getting started.
