Advanced LLM Systems

Production RAG, Fine Tuning, JSON Extraction, and Multimodal AI Pipelines

Slide 109

Overview

Modern LLM systems integrate retrieval‑augmented generation, advanced fine‑tuning, structured output generation, and multimodal processing to support production‑grade AI workflows across enterprise environments.

Key Concepts

Production‑Ready RAG

High‑reliability retrieval pipelines with scalable embeddings, metadata filtering, ranking, and caching.

Fine Tuning

Domain‑adapted LLM behavior through supervised datasets, preference tuning, and high‑signal examples.

JSON Extraction

Reliable structured output with constrained decoding, JSON schemas, and function‑calling interfaces.

Multimodal Pipelines

Integration of text, images, audio, and video into unified inference and retrieval flows.

How It Works

1

Data Ingestion

Text, documents, images, API data, and domain corpora.

2

Embedding + Retrieval

Indexing, vector search, ranking, and hybrid retrieval.

3

LLM Reasoning

RAG‑enhanced reasoning, multimodal fusion, tool calls.

4

Structured Output

JSON, function calls, dashboards, or downstream automation.

Use Cases

Comparison

Prompt‑Only

Best for small tasks; limited accuracy for domain‑specific needs.

RAG Systems

Improves reliability with external knowledge and real‑time updates.

Fine‑Tuned LLMs

Highest domain alignment and custom capabilities.

FAQ

Do I need both RAG and fine tuning?

Most production systems combine both for best accuracy and consistency.

How do I ensure JSON is valid?

Use structural constraints, schemas, or function calling interfaces.

Can multimodal models replace specialized pipelines?

Often they augment them; full replacement depends on latency and complexity needs.
