Be it creating a Q&A chatbot or a smart search app, LlamaIndex employs retrieval-augmented generation (RAG) to anchor LLMs with your data, ensuring responses are apt and on the mark. It's quick enough for a quick test spin but sturdy enough for advanced projects—picture it as your workbench for AI.
LlamaIndex Pricing
And now, let's talk credits—because who wouldn't want a good deal? LlamaIndex is open source and free, which is a huge plus for frugal developers. You can dive in, try, and build without a single cent to spend. But wait, there's more: its LlamaParse service, which is utilized to import sophisticated documents like PDFs, has a 7,000-page-per-week free tier. Need more? It's just $3 per 1,000 pages after that—not any hidden fees, not any hassle. Even better, there's a preview SaaS private version as of early 2025 with hints at cloud of pro features soon after, but more than plenty free-ness to start for the moment. No trials and no refunds to offer when the underlying price is zero!
