RHEL AI Use Cases: Real-World Enterprise Applications

📘 Book Reference: This article is based on Chapter 7: Use Cases of Practical RHEL AI, showcasing real-world enterprise applications running on Red Hat Enterprise Linux AI.

Introduction

Chapter 7 of Practical RHEL AI presents four comprehensive use cases that demonstrate the platform’s versatility for enterprise AI workloads. Each case study includes architecture patterns, implementation details, and production considerations.

Use Case 1: Underwriting Classification

Business Context

Insurance companies process thousands of applications daily, requiring consistent risk assessment. RHEL AI enables automated underwriting classification with explainable decisions.

    Granite --> Risk["Risk Score<br/>+ Explanation"]
    Granite --> SPDX["SPDX<br/>Lineage"]

Implementation

from instructlab import Classifier
from vllm import LLM

# Load fine-tuned underwriting model
model = LLM(
    model="granite-underwriting-v1",
    tensor_parallel_size=2
)

def classify_application(application_data):
    prompt = f"""
    Analyze this insurance application and provide:
    1. Risk classification (Low/Medium/High)
    2. Key risk factors identified
    3. Recommended premium adjustment
    
    Application: {application_data}
    """
    
    response = model.generate(prompt, max_tokens=500)
    return parse_classification(response)

Use Case 2: Multilingual Chatbots

Business Context

Global enterprises need customer support in multiple languages. RHEL AI supports fine-tuning for domain-specific multilingual capabilities.

Supported Languages

The Granite and Mixtral models support:

• English, Spanish, French, German, Italian
• Portuguese, Dutch, Chinese, Japanese, Korean
• Arabic, Hindi, and 20+ additional languages

Implementation

# taxonomy/multilingual-support/qna.yaml
created_by: enterprise-team
version: 1
seed_examples:
  - context: |
      Customer inquiries about product returns in Spanish
    question: "¿Cómo puedo devolver un producto?"
    answer: |
      Para devolver un producto, siga estos pasos:
      1. Inicie sesión en su cuenta
      2. Vaya a 'Mis pedidos'
      3. Seleccione el artículo a devolver
      4. Complete el formulario de devolución

Deployment with vLLM

from vllm import LLM, SamplingParams

# Multi-language chatbot configuration
chatbot = LLM(
    model="granite-multilingual-chat",
    tensor_parallel_size=4,
    max_model_len=8192
)

# Language detection and routing
def handle_query(user_message, detected_language):
    system_prompt = get_system_prompt(detected_language)
    
    response = chatbot.generate(
        prompts=[f"{system_prompt}\n\nUser: {user_message}"],
        sampling_params=SamplingParams(
            temperature=0.3,
            max_tokens=1024
        )
    )
    return response

Use Case 3: RAG (Retrieval-Augmented Generation)

Business Context

Enterprises need AI that can answer questions using proprietary documentation while maintaining accuracy and providing citations.

Architecture Components

As detailed in Chapter 7:

• Vector Store: Milvus or Chroma for embeddings
• Embedding Model: Granite embeddings
• LLM: Fine-tuned Granite for response generation
• RHEL AI: Orchestration and serving

Implementation

from langchain.vectorstores import Milvus
from langchain.embeddings import HuggingFaceEmbeddings
from vllm import LLM

# Initialize vector store
embeddings = HuggingFaceEmbeddings(
    model_name="granite-embedding-v1"
)

vectorstore = Milvus(
    embedding_function=embeddings,
    connection_args={"host": "localhost", "port": "19530"},
    collection_name="enterprise_docs"
)

# RAG pipeline
def answer_with_sources(query):
    # Retrieve relevant documents
    docs = vectorstore.similarity_search(query, k=5)
    
    # Generate response with citations
    context = "\n".join([doc.page_content for doc in docs])
    
    prompt = f"""
    Answer based on the following context. Include citations.
    
    Context: {context}
    
    Question: {query}
    """
    
    response = llm.generate(prompt)
    return response, docs

Use Case 4: Edge Sentiment Analysis

Business Context

Retail and hospitality need real-time sentiment analysis at edge locations for immediate customer feedback processing.

Edge Deployment Architecture

    subgraph Edge["Edge Location"]
        Sensors["Sensors<br/>IoT"] --> RHEL["RHEL AI Edge<br/>(Quantized)"]
        RHEL --> Actions["Local Actions<br/>Alerts"]
    end
    
    RHEL --> Central["Central RHEL AI<br/>(Aggregation)"]

Quantized Model for Edge

from optimum.intel import OVQuantizer
from transformers import AutoModelForSequenceClassification

# Quantize for edge deployment
model = AutoModelForSequenceClassification.from_pretrained(
    "granite-sentiment-v1"
)

quantizer = OVQuantizer.from_pretrained(model)
quantizer.quantize(
    save_directory="./edge-sentiment-int8",
    quantization_config={"bits": 8}
)

Real-Time Processing

import asyncio
from collections import deque

class EdgeSentimentProcessor:
    def __init__(self, model_path):
        self.model = load_quantized_model(model_path)
        self.recent_sentiments = deque(maxlen=100)
        self.alert_threshold = 0.3  # Negative sentiment ratio
    
    async def process_feedback(self, text):
        sentiment = self.model.predict(text)
        self.recent_sentiments.append(sentiment)
        
        # Check for negative trend
        if self.calculate_negative_ratio() > self.alert_threshold:
            await self.trigger_alert()
        
        return sentiment

Cross-Cutting Concerns

SPDX Lineage Tracking

All use cases implement SPDX lineage tracking for model provenance:

{
  "SPDXID": "SPDXRef-Model-Underwriting-v1",
  "spdxVersion": "SPDX-2.3",
  "name": "granite-underwriting-v1",
  "downloadLocation": "registry.redhat.io/rhel-ai/models",
  "relationships": [
    {
      "spdxElementId": "SPDXRef-BaseModel",
      "relatedSpdxElement": "SPDXRef-Granite-3B",
      "relationshipType": "DERIVED_FROM"
    }
  ]
}

Ansible Automation

Deploy any use case with Ansible:

# deploy-use-case.yml
- name: Deploy RHEL AI Use Case
  hosts: ai_servers
  vars:
    use_case: "underwriting"
    model_version: "v1.2"
  
  tasks:
    - name: Pull model container
      containers.podman.podman_image:
        name: "registry.redhat.io/rhel-ai/{{ use_case }}"
        tag: "{{ model_version }}"
    
    - name: Deploy vLLM service
      ansible.builtin.include_role:
        name: rhel_ai_vllm
