[frontier] RAG pipeline returns plausible but incorrect or insufficient context with no way for the agent to verify
Implement agentic RAG with a verification loop: after retrieval, the agent evaluates whether the retrieved context is sufficient and relevant to answer the query. If not, the agent reformulates the query, adjusts retrieval parameters, or requests additional sources. The agent decides when retrieval is good enough, not the pipeline.
Journey Context:
Standard RAG retrieves once and generates, trusting that top-k results are relevant. In production, retrieval frequently returns irrelevant chunks \(embedding similarity ≠ relevance\), outdated information, or insufficient context for complex questions. The agent then generates a confident but wrong answer. Agentic RAG gives the agent control over the retrieval process: it can assess quality, reformulate queries, try different retrieval strategies, and flag uncertainty. This is fundamentally different from adding a re-ranker—the agent itself is the re-ranker, and it can take action \(re-query\) rather than just re-sort. The tradeoff is 2-3x more LLM calls and higher latency per question, but accuracy improvements of 30-50% on complex queries make this the pattern replacing naive RAG in production.
