Frequently asked questions about AI Infrastructure Tools

Real answers from real users, pulled straight from launch discussions, forums, and reviews.

  • Q: How do vector databases in AI infrastructure compare for RAG performance? 

    Hugging Face's model cards show why source transparency matters for RAG: knowing training data and tags helps you pick what to index and trust.

    • Integration & observability: use tools that let you evaluate LLMs and retrieval together — e.g., Langfuse can monitor multiple model providers in one dashboard so you can compare end-to-end RAG quality.
    • Hosting & privacy: self-hosted options like n8n highlight why data sovereignty matters for vector stores holding sensitive docs.

    Focus selection on (1) retrieval accuracy, (2) latency/scale, (3) privacy controls, and (4) monitoring/analytics to measure real RAG performance in your stack.

  • Q: How do LLM engineering platforms help with observability and cost tracking? 

    Langfuse centralizes traces, prompts, and evaluations so you can see what your LLMs are doing and why. Key ways these platforms help:

    • Unified tracing & debugging: integrated debugging and analysis tools surface input/output traces and reasoning steps so you can spot failures fast.
    • Multi-provider analytics: one dashboard to monitor models from OpenAI, Google, Anthropic, etc., making it easier to compare usage and performance across providers.
    • Cost control options: open-source / non‑per‑user pricing and self‑hosting let teams avoid per‑seat fees and directly manage infra spend.

    Together these features speed iteration and make behavioral and spend tradeoffs easier to act on.

  • Q: Which AI infrastructure is best for building agentic workflows and tool use? 

    n8n + OpenAI + Langfuse is a practical stack for agentic workflows and tool use.

    • Orchestration: n8n’s self-hosted, visual builder and custom-JS nodes handle complex multi-step logic and proprietary APIs while preserving data sovereignty. Ideal for connecting tools and composing agent pipelines.
    • Models: OpenAI provides strong, reliable models with fast APIs—good for intent-aware reasoning and production use.
    • Observability & debugging: Langfuse helps trace, evaluate, and debug agent reasoning steps and outputs so you can iterate safely.

    Use self-hosting (n8n) when privacy/compliance matters; use Langfuse to monitor agent behavior in production.
