Why Powerful AI Models Still Fail: The Real Infrastructure Challenges of Agents

Despite ever‑more capable large language models, AI agents frequently stumble because enterprise data is messy, pipelines introduce errors, RAG lacks timeliness and conflict resolution, and context assembly requires dedicated ingestion, resolution, selection, decay, and inference layers, plus a harness to manage execution and governance.
