| content.faq | `[{"answer":"LlamaParse is a cloud-based document parsing platform that uses vision language models and intelligent agents to automatically process complex documents—including PDFs, images, and office files—with support for layout detection, multi-modal content, and 80+ languages. It transforms document ingestion workflows with agentic extraction and indexing capabilities. It is indexed under MLOps & LLMOps Tools.","source":"https://www.llamaindex.ai/pricing","question":"What is LlamaIndex?","confidence":0.6},{"answer":"LlamaIndex is open source, so it can be self-hosted and used at no licence cost. It is released under the MIT licence. A commercial or hosted edition starts at $50 per month. Prices are published openly on the vendor's own pricing page. Pricing changes often, so verify at source before relying on it.","source":"https://www.llamaindex.ai/pricing","question":"Is LlamaIndex free to use?","confidence":0.6},{"answer":"We have confirmed browser-based access to LlamaIndex. That is the extent of what we could verify from public sources, so it may well offer desktop or mobile clients we have not indexed.","source":"https://www.llamaindex.ai/pricing","question":"What platforms does LlamaIndex support?","confidence":0.6},{"answer":"Not fully, on what we have confirmed. LlamaIndex is offered as cloud / SaaS and hybrid, and a hybrid deployment usually means some components can run on your own infrastructure while the rest stays vendor-hosted. We have not confirmed a completely self-hosted option, so check with the vendor if that is a requirement.","source":"https://www.llamaindex.ai/pricing","question":"Can LlamaIndex be self-hosted?","confidence":0.6},{"answer":"We have confirmed 3 integrations for LlamaIndex, including AWS, Microsoft Azure and GitHub. This is what we could verify from public sources, so the vendor may support others we have not indexed.","source":"https://www.llamaindex.ai/pricing","question":"What does LlamaIndex integrate with?","confidence":0.6},{"answer":"We have independently confirmed SOC 2, HIPAA and GDPR for LlamaIndex. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as LlamaIndex not holding them. Always confirm compliance directly before you rely on it.","source":"https://www.llamaindex.ai","question":"What security certifications does LlamaIndex have?","confidence":0.48},{"answer":"Yes. LlamaIndex is published under the MIT licence, a permissive licence that generally allows commercial use and modification. Licence terms can change between releases, so verify against the repository for the version you intend to use.","source":"https://github.com/run-llama/llama_index","question":"Is LlamaIndex open source?","confidence":0.95},{"answer":"LlamaIndex is available worldwide. Its primary markets are the United States and the EU. The vendor is headquartered in the United States.","source":"https://www.llamaindex.ai/pricing","question":"Where is LlamaIndex available?","confidence":0.75}]` | `[{"answer":"An open-source framework that provides optimized LLM inference with low latency and high throughput. It includes continuous batching, memory-efficient attention mechanisms, quantization support, and distributed serving across diverse hardware platforms.
