Validate activity before betting a new project on fast-llm-security-guardrails. - AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism. - Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. ## Common questions ### What is the difference between moby and fast-llm-security-guardrails? moby: The Moby Project - a collaborative project for the container ecosystem to assemble container-based systems. fast-llm-security-guardrails: The fastest Trust Layer for AI Agents.
