Is Fine-Tuning Still Needed? LLMs, RAG, & LoRA Jul 21, 2026 · 10:52 Martin Keen explains how LLM fine tuning compares to RAG, LoRA, and generative AI techniques, outlining when custom model training is still necessary in modern AI workflows. Understanding AI Agent Hallucination in AI Systems Aug 2, 2026 · 10:51 Hallucination is when an AI system confidently gives information that's totally incorrect. As agents take action, grounding them with tools and defining scope are critical design choices. Your Fine-Tuned Model Is Tech Debt: A 50x ROI House of Cards — Dan Bjornn, Lease End Aug 20, 2026 · 16:39 Fine-tuning LLMs can create a 'calcification tax,' leading to architectural lock-in. Migrating to an agentic framework using skills and context reduced fix deployment time from weeks to under an hour.

Automating document work with Long-Horizon AI Agents at LlamaIndex Oct 13, 2026 · 36:53 The future of enterprise AI lies in long-running agents that automate document workflows. We explore the advanced document context layer, covering specialized OCR, agent harnesses, and optimizing models for cost and accuracy. Beyond RAG: A Relational Context Engine That Cuts Token Burn — Unblocked Oct 10, 2026 · 19:44 Learn how a Context Engine moves beyond vector search to handle structural, relational, and temporal data queries, significantly improving AI agent reliability and cutting token burn. Grep or Embeddings? Agentic Search Over Company Documents — George He, LlamaIndex Oct 7, 2026 · 23:22 For enterprise data, simple file traversal fails. We need an agentic 'harness' that combines hybrid search, metadata filtering, and specialized parsing (LlamaParse) to ground answers from massive, multimodal corporate documents.
