[frontier] RAG retrieves relevant documents but generation still produces hallucinations or incorrect synthesis of retrieved facts

Replace naive RAG with Tool-Augmented Generation \(TAG\) - use deterministic tools \(code execution, calculators, LLM-as-judge\) to transform, verify, and augment retrieved content before final generation, ensuring factual grounding.

Journey Context:
Instead of the simple retrieve-then-generate pipeline, leading systems are inserting a deterministic processing layer where retrieved documents are fed into tools for transformation: using code interpreters to calculate derived values from retrieved tables, LLM-as-judge to verify claims against retrieved text, or structured extraction tools to normalize formats. Only after this augmentation step does the final generation occur. This is distinct from agentic RAG \(where the agent decides what to retrieve\) because it's deterministic tool use on already-retrieved data. The pattern comes from the TAG \(Tool Augmented Generation\) research and is being adopted in production because it reduces hallucinations by ensuring the LLM only synthesizes pre-verified facts.
