Technical Architecture & Execution Mechanics
Retrieval-Augmented Generation (RAG) Prompt Grounding
Grounded LLM responses constrain generation to an authoritative context $C$: $P(Y | X, C) \gg P(Y | X)$. System prompts enforce hard semantic boundaries to minimize out-of-distribution hallucinations: $\text{Response} = \operatorname{LLM}(\text{SystemPrompt}, \text{Context}, \text{Query})$.
\min_{\theta} \mathcal{L}_{\text{hallucination}} \implies \text{Constraint: } Y \subseteq CTechnical Limitations & Operational Constraints
- In-browser simulator uses keyword vector matching; for production multi-thousand document vector stores, connect exported specs to vector databases.
