Reviewer scorecard
“Best framework for RAG specifically. The data connectors and query engines are production-grade. Less bloated than LangChain.”
“Enterprise pricing only. Not accessible for smaller teams. The RLHF data services are their differentiator.”
“Focused scope makes it more maintainable than LangChain. LlamaCloud managed parsing is genuinely useful.”
“Important for training frontier models but irrelevant for 99% of AI developers. Enterprise-only play.”
“Data integration is the real bottleneck for enterprise AI. LlamaIndex is correctly positioned at this chokepoint.”
“The data engine for AI is as important as the compute engine. Scale's position in frontier model training is unique.”
