Organizes LLM education into three progressive learning tracks (Fundamentals, Scientist, Engineer) with explicit entry points and dependency mapping, implemented as a single markdown hub that links to ~150+ external resources. Users navigate via a hierarchical section structure that maps learning paths to specific topics, with each topic following a consistent pattern of curated articles, videos, and tools. The architecture uses a documentation-first approach where the README.md acts as a central knowledge graph rather than containing executable code.
Unique: Uses a three-track learning path architecture (Fundamentals/Scientist/Engineer) with explicit optional vs. core topic designation, enabling learners to skip prerequisites based on background. Most LLM courses use linear progression; this enables parallel tracks with clear entry points.
vs alternatives: More structured and goal-oriented than generic LLM resource lists (e.g., Awesome-LLM), with explicit learning paths vs. flat collections of links
Aggregates 24 theoretical topics across three learning paths and embeds curated external references (articles, papers, videos, tools) directly within each topic section. Implementation uses a consistent topic section pattern where each topic links to 3-8 external resources selected for pedagogical value. The curation layer filters and organizes content from diverse sources (research papers, blog posts, YouTube, GitHub projects) into a single navigable structure without duplicating content.
Unique: Implements a consistent topic section pattern (theory + curated resources + tools) across 24 topics, enabling predictable navigation. Each topic embeds ~3-8 hand-selected external resources rather than generating them, ensuring quality over quantity.

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.
llm-course scores higher at 41/100 vs vectra at 41/100. llm-course leads on adoption and quality, while vectra is stronger on ecosystem.
