Slide 106

Overview

Modern LLM systems combine retrieval, tuning, structured outputs, and multimodal reasoning. This page summarizes the essential components used in real-world AI pipelines inspired by slide 106.

Key Concepts

Production RAG

Combines retrieval engines with LLMs for grounded responses. Includes chunking, vector search, reranking, and caching.

Fine Tuning

Adapts models for domain language, tasks, or output style. Useful when prompt engineering alone is insufficient.

JSON Extraction

Ensures predictable structured outputs for APIs, automation, or downstream processing.

Multimodal Pipelines

Blend text, images, data, and audio to enable richer contextual reasoning in enterprise applications.

How the Pipeline Works

1. Ingestion

Collect and prepare structured/unstructured sources.

2. Retrieval

Embed, index, and query relevant context.

3. LLM Processing

Model generates grounded or tuned outputs.

4. Structured Output

Return JSON or multimodal results for apps.

Use Cases

Document Assistants

Use RAG + extraction to produce structured summaries, audits, or answers.

Enterprise Knowledge Apps

Scale internal search and reasoning with tuned models.

Multimodal QA Systems

Analyze PDFs, images, diagrams, and text together.

Comparison

Traditional LLM Workflows

  • Prompt-only solutions
  • Limited context accuracy
  • Unstructured outputs
  • Not optimized for scale

Advanced AI Pipelines

  • Retrieval-augmented workflows
  • Tuned models for precision
  • Reliable JSON extraction
  • Multimodal context ingestion

FAQ

Do you always need fine tuning?

Not always. RAG often eliminates the need unless extreme precision is required.

When is structured JSON output essential?

Anytime automation, integrations, or downstream processing is needed.

Why multimodal pipelines?

Real-world data spans text, images, documents, and audio; multimodal systems improve accuracy and reasoning.
