LlamaIndex lebih kuat untuk solusi retrieval\u2011first\/RAG dan aplikasi document\u2011heavy berkat ekosistem konektor dan index tingkat lanjut. Untuk banyak kasus produksi, pendekatan hybrid (LlamaIndex sebagai retriever + LangChain untuk orchestration) sering jadi pilihan praktis.<\/p>\n<p>Referensi dokumentasi:<\/p>\n<ul>\n<li><a href=\"https:\/\/python.langchain.com\/\" target=\"_blank\" rel=\"noopener noreferrer\">LangChain docs<\/a><\/li>\n<li><a href=\"https:\/\/docs.llamaindex.ai\/\" target=\"_blank\" rel=\"noopener noreferrer\">LlamaIndex docs<\/a><\/li>\n<li><a href=\"https:\/\/langchain-ai.github.io\/langgraph\/\" target=\"_blank\" rel=\"noopener noreferrer\">LangGraph (stateful graphs)<\/a><\/li>\n<li><a href=\"https:\/\/bit.ly\/langllama-bench\" target=\"_blank\" rel=\"noopener noreferrer\">Benchmarks repo<\/a><\/li>\n<\/ul>\n<\/section>\n<section>\n<h2 id=\"apa-itu-langchain-dan-llamaindex\">Apa itu LangChain dan LlamaIndex?<\/h2>\n<h3 id=\"ringkasan-langchain\">Ringkasan LangChain<\/h3>\n<p>LangChain adalah framework orchestration LLM general\u2011purpose dengan building blocks seperti chains, agents, tools, retrievers, dan memory \u2014 ditujukan untuk membangun agen yang dapat memanggil tool, reasoning multi\u2011step, dan integrasi API. (Dokumentasi: <a href=\"https:\/\/python.langchain.com\/\" target=\"_blank\" rel=\"noopener noreferrer\">LangChain docs<\/a>).

Framework ini menawarkan abstractions seperti nodes, indices, dan query engines, serta banyak connector untuk sumber dokumen enterprise (<a href=\"https:\/\/docs.llamaindex.ai\/\" target=\"_blank\" rel=\"noopener noreferrer\">LlamaIndex docs<\/a>).
