Provides a curated dataset of 1 trillion tokens spanning 539,406 PDF documents with aligned image-to-text pairs extracted from Common Crawl 2023-06 snapshot. The dataset uses a hierarchical indexing structure that maps document boundaries, page-level image coordinates, and corresponding OCR/text extractions, enabling efficient retrieval of multimodal training samples at scale without requiring full dataset materialization in memory.
Unique: Combines 1 trillion tokens of document text with aligned page-level images from a single Common Crawl snapshot, providing temporally-consistent multimodal pairs at unprecedented scale — most competing datasets either use synthetic image-text pairs or lack document-level coherence across modalities
vs alternatives: Larger and more document-focused than LAION-5B (which emphasizes web images) and more naturally-paired than synthetic datasets like Synthetic Docvqa, with real-world OCR challenges that improve model robustness
Implements HuggingFace Datasets streaming protocol that enables on-demand loading of document samples without downloading the full 1T token dataset upfront. The architecture uses memory-mapped file access and configurable batch sampling strategies, allowing training loops to fetch and cache only the samples needed for each epoch while maintaining deterministic shuffling across distributed workers.
Unique: Uses HuggingFace's streaming protocol with deterministic shuffling and worker-aware sharding, enabling true distributed training without pre-downloading — avoids the storage bottleneck that limits competitors like LAION-5B when used in multi-node setups
vs alternatives: More practical for large-scale training than downloading full datasets upfront, and more deterministic than ad-hoc web scraping approaches that lack reproducibility
Maintains structured metadata for each document including source URL, Common Crawl snapshot date (2023-06), document hash, page count, and extraction quality scores. This metadata is queryable and filterable within the dataset, allowing users to select subsets based on source domain, quality thresholds, or temporal characteristics without scanning the full corpus.
Unique: Embeds Common Crawl provenance (URLs, crawl dates, document hashes) directly in the dataset schema, enabling reproducible filtering and bias analysis — most competing datasets either lack this metadata or store it separately, making it harder to correlate quality with source
vs alternatives: Provides better auditability and reproducibility than datasets without source tracking, and more granular filtering than datasets with only aggregate statistics
Extracts page-level images from PDF documents and aligns them with corresponding OCR/text content using spatial layout information (bounding boxes, reading order). The extraction pipeline preserves document structure (headers, footers, tables, body text) by analyzing PDF internal structure and image coordinates, creating naturally-aligned multimodal pairs suitable for vision-language model training without requiring post-hoc alignment.
Unique: Preserves document layout structure through PDF internal coordinate systems rather than post-hoc image analysis, enabling structurally-aware alignment that captures reading order and spatial relationships — most competing datasets either discard layout information or infer it from image analysis alone
vs alternatives: More accurate layout alignment than image-only document datasets, and more scalable than manually-annotated document datasets like DocVQA
Dataset is derived from a single Common Crawl snapshot (2023-06), ensuring temporal consistency across all documents — all PDFs were crawled within a specific time window, avoiding temporal distribution shifts that occur when combining data from multiple crawl dates. The integration includes Common Crawl metadata (WARC records, crawl IDs) enabling users to trace documents back to original crawl artifacts for verification or re-extraction.
Unique: Anchors entire dataset to a single Common Crawl snapshot (2023-06) with traceable WARC references, ensuring temporal consistency and reproducibility — most competing web-derived datasets either combine multiple crawl dates or lack explicit Common Crawl integration
vs alternatives: More reproducible than datasets combining multiple crawl dates, and more verifiable than proprietary datasets without public provenance
Dataset is released under Creative Commons Attribution 4.0 (CC-BY-4.0) license, permitting commercial use, modification, and redistribution with attribution. The license is applied at the dataset level, though individual documents may have different licenses — users are responsible for verifying compliance for derived works, but the dataset itself imposes minimal legal restrictions on model training and deployment.
Unique: Explicitly licensed under CC-BY-4.0 with clear commercial use rights, reducing legal friction for commercial model training — many competing datasets either lack explicit licensing or use more restrictive licenses (e.g., non-commercial only)
vs alternatives: More commercially-friendly than datasets with non-commercial restrictions, and more legally transparent than datasets with unclear licensing
Stores vector embeddings and metadata in JSON files on disk while maintaining an in-memory index for fast similarity search. Uses a hybrid architecture where the file system serves as the persistent store and RAM holds the active search index, enabling both durability and performance without requiring a separate database server. Supports automatic index persistence and reload cycles.
Unique: Combines file-backed persistence with in-memory indexing, avoiding the complexity of running a separate database service while maintaining reasonable performance for small-to-medium datasets. Uses JSON serialization for human-readable storage and easy debugging.
vs alternatives: Lighter weight than Pinecone or Weaviate for local development, but trades scalability and concurrent access for simplicity and zero infrastructure overhead.
Implements vector similarity search using cosine distance calculation on normalized embeddings, with support for alternative distance metrics. Performs brute-force similarity computation across all indexed vectors, returning results ranked by distance score. Includes configurable thresholds to filter results below a minimum similarity threshold.
Unique: Implements pure cosine similarity without approximation layers, making it deterministic and debuggable but trading performance for correctness. Suitable for datasets where exact results matter more than speed.
vs alternatives: More transparent and easier to debug than approximate methods like HNSW, but significantly slower for large-scale retrieval compared to Pinecone or Milvus.
Accepts vectors of configurable dimensionality and automatically normalizes them for cosine similarity computation. Validates that all vectors have consistent dimensions and rejects mismatched vectors. Supports both pre-normalized and unnormalized input, with automatic L2 normalization applied during insertion.
vectra scores higher at 41/100 vs MINT-1T-PDF-CC-2023-06 at 26/100.

Search the match graph →© 2026 Unfragile. Stronger through disorder.
Unique: Automatically normalizes vectors during insertion, eliminating the need for users to handle normalization manually. Validates dimensionality consistency.
vs alternatives: More user-friendly than requiring manual normalization, but adds latency compared to accepting pre-normalized vectors.
Exports the entire vector database (embeddings, metadata, index) to standard formats (JSON, CSV) for backup, analysis, or migration. Imports vectors from external sources in multiple formats. Supports format conversion between JSON, CSV, and other serialization formats without losing data.
Unique: Supports multiple export/import formats (JSON, CSV) with automatic format detection, enabling interoperability with other tools and databases. No proprietary format lock-in.
vs alternatives: More portable than database-specific export formats, but less efficient than binary dumps. Suitable for small-to-medium datasets.
Implements BM25 (Okapi BM25) lexical search algorithm for keyword-based retrieval, then combines BM25 scores with vector similarity scores using configurable weighting to produce hybrid rankings. Tokenizes text fields during indexing and performs term frequency analysis at query time. Allows tuning the balance between semantic and lexical relevance.
Unique: Combines BM25 and vector similarity in a single ranking framework with configurable weighting, avoiding the need for separate lexical and semantic search pipelines. Implements BM25 from scratch rather than wrapping an external library.
vs alternatives: Simpler than Elasticsearch for hybrid search but lacks advanced features like phrase queries, stemming, and distributed indexing. Better integrated with vector search than bolting BM25 onto a pure vector database.
Supports filtering search results using a Pinecone-compatible query syntax that allows boolean combinations of metadata predicates (equality, comparison, range, set membership). Evaluates filter expressions against metadata objects during search, returning only vectors that satisfy the filter constraints. Supports nested metadata structures and multiple filter operators.
Unique: Implements Pinecone's filter syntax natively without requiring a separate query language parser, enabling drop-in compatibility for applications already using Pinecone. Filters are evaluated in-memory against metadata objects.
vs alternatives: More compatible with Pinecone workflows than generic vector databases, but lacks the performance optimizations of Pinecone's server-side filtering and index-accelerated predicates.
Integrates with multiple embedding providers (OpenAI, Azure OpenAI, local transformer models via Transformers.js) to generate vector embeddings from text. Abstracts provider differences behind a unified interface, allowing users to swap providers without changing application code. Handles API authentication, rate limiting, and batch processing for efficiency.
Unique: Provides a unified embedding interface supporting both cloud APIs and local transformer models, allowing users to choose between cost/privacy trade-offs without code changes. Uses Transformers.js for browser-compatible local embeddings.
vs alternatives: More flexible than single-provider solutions like LangChain's OpenAI embeddings, but less comprehensive than full embedding orchestration platforms. Local embedding support is unique for a lightweight vector database.
