It supports direct integrz ## Choose when ### Choose fastembed-rs if… - fastembed-rs is primarily Rust; llm-app is Jupyter Notebook. - License: fastembed-rs is Apache-2.0, llm-app is MIT. - Tags unique to fastembed-rs: embeddings, fastembed, reranker, rag. ### Choose llm-app if… - llm-app is primarily Jupyter Notebook; fastembed-rs is Rust. - License: llm-app is MIT, fastembed-rs is Apache-2.0. - Requirements: Requires Docker; The tool is Docker-friendly and designed to ensure synchronization with cloud-based storage solutions among others.. - Tags unique to llm-app: vector-database, llm, hugging-face, chatbot. - - You need a ready-to-run solution that directly integrates with various data sources like Sharepoint, Google Drive, S3, Kafka, PostgreSQL, and live APIs. ## When NOT to use fastembed-rs - Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. - Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough. ## When NOT to use llm-app - - You require custom deployment configurations that extend beyond the pre-set cloud templates available through llm-app. - - There’s a need for tightly integrated support with data sources or APIs not explicitly mentioned, such as specialized CRM systems (Salesforce), which may lack direct template support in llm-app. ## Common questions ### What is the difference between fastembed-rs and llm-app? fastembed-rs: Rust library for generating vector embeddings, reranking locally!. llm-app: Ready-to-run cloud templates for RAG, AI pipelines, and enterprise search with live data..
