Practical AI Server Use Cases for Your Business

AI servers with powerful GPUs open up completely new possibilities for companies. But what are the specific use cases? And what technical requirements do they bring?

On this page we show you real application scenarios in which companies are already successfully using AI servers. With detailed information on technical requirements, ROI examples and specific implementation details.

Whether you want to automate customer processes, optimize quality control, or build internal knowledge management systems – the following use cases will show you the way.

USE CASE #1

AI Chatbots & Conversational AI

24/7 customer support & internal knowledge bases

Chatbots based on large language models (LLMs) are revolutionizing customer service. In contrast to rule-based systems, modern LLM chatbots understand context, can process complex requests and communicate naturally.

What are AI Chatbots?

AI chatbots use Large Language Models (LLMs) like Llama, Gemma, or DeepSeek to conduct human-like conversations. They can be trained on company data and access current information via RAG (Retrieval-Augmented Generation).

Typical use cases are customer support, internal IT helpdesks, HR assistants, and sales consulting. The bots can independently resolve 80-90% of standard queries.

Technical Requirements

  • GPU: NVIDIA RTX 4000 Ada (20 GB VRAM) for up to 13B models
  • CPU: 8+ cores for parallel request processing
  • RAM: 32-64 GB for model caching
  • Storage: 500 GB SSD for models, logs, and vector DB
  • Software: Ollama/vLLM, OpenWebUI, Vector DB (ChromaDB/Weaviate)

Cost Reduction

60-80% lower support costs through automation of standard queries

Availability

24/7 support without additional staff or shift work

Consistency

Uniform, high-quality answers without quality fluctuations

Scalability

Handling thousands of parallel requests without performance loss

Ollama vs. vLLM: Choosing the Right Framework

We offer both frameworks for different requirements

O

Ollama

Ideal for: Development, prototyping, simple setups with few concurrent users. Very user-friendly and quick to set up.

vLLM

vLLM

Ideal for: Production environments with high throughput, many concurrent users, low latency. Up to 24x higher throughput than Ollama for large models.

Recommendation: Start with Ollama for proof-of-concept, switch to vLLM for production deployments with >50 concurrent users.

Example Setup: E-Commerce Support Bot

Building a customer support chatbot for an online shop

Model: Llama 3.1 8B (fast, efficient, good tool usage)

RAG System: ChromaDB with product catalog, FAQ, return policies

Interface: OpenWebUI with custom branding

Integration: REST API for website, CRM connection

Result: 85% Automatic Resolution Rate, 24/7 availability, ROI after 6 months

USE CASE #2

Computer Vision & Video Analysis

Automated quality control, security monitoring & more

Computer vision applications require intensive GPU calculations for real-time image analysis. From quality control in production to intelligent video surveillance – the use cases are diverse.

What is Computer Vision?

Computer vision uses deep learning models to analyze images and videos. Modern models can recognize objects, detect anomalies, track movements, and determine quality metrics.

Typical applications: production defect detection, security & access controls, medical image analysis, retail analytics (customer behavior), and logistics automation.

Technical Requirements

  • GPU: NVIDIA RTX 6000 Blackwell Max-Q (96 GB VRAM) for real-time processing
  • CPU: 16+ cores for video decoding and pre-processing
  • RAM: 64-128 GB for batch processing and frame caching
  • Storage: 2+ TB NVMe for video data and model checkpoints
  • Software: YOLO, PyTorch, TensorFlow, OpenCV, CUDA Toolkit

Precision

99%+ detection rate for quality defects, better than human inspectors

Speed

Real-time analysis at 60+ FPS, no delays in production flow

Cost Efficiency

90% fewer manual inspections, ROI within 12-18 months

Continuity

24/7 operation without fatigue or quality loss

Example Setup: Production Quality Control

Automatic defect detection in production line

Model: YOLOv8 custom-trained for specific product defects

Hardware: 4x cameras (4K), RTX 6000 Blackwell Max-Q, real-time processing

Pipeline: Frame Capture → GPU Inference → Defect Classification → Alert

Integration: SCADA system, automatic rejection of defective parts

Result: 99.2% detection rate, 0% false negatives, 15% waste reduction

USE CASE #3

RAG & Enterprise Knowledge Management

Intelligent document search & knowledge management with LLMs

RAG (Retrieval Augmented Generation) combines the power of LLMs with the company's own data sources. This enables employees to access the entire company knowledge in natural language.

What is RAG?

RAG extends LLMs with the ability to access external knowledge databases. Documents are converted into vector embeddings and stored in a vector database. On queries, relevant context is retrieved and provided to the LLM.

Use cases: enterprise search, compliance & legal research, engineering documentation, onboarding assistants, and research & development.

Technical Requirements

  • GPU: NVIDIA RTX 4000 Ada (20 GB) for embedding generation
  • CPU: 12+ cores for document processing
  • RAM: 64 GB for large document batches
  • Storage: 1+ TB SSD for vector DB and document archives
  • Software: Weaviate/ChromaDB, Llama 3.1, LangChain, Unstructured.io

Time Savings

80% faster information retrieval compared to manual search

Knowledge Transfer

Democratization of expert knowledge, faster onboarding of new employees

Compliance

Data stays in your own data center, GDPR compliant

Actuality

Always access to latest documents and policies

Example Setup: Engineering Documentation System

Intelligent search in technical documents and manuals

Document base: 50,000+ PDFs, technical specs, CAD descriptions

Embedding model: all-MiniLM-L6-v2 for fast vectorization

LLM: Llama 3.1 70B for complex technical queries

Vector DB: Weaviate with hybrid search (dense + sparse)

Result: 85% fewer support tickets, 4h/week time savings per engineer

Frequently Asked Questions

Which use case fits my company?

It depends on your business processes. Do you have recurring support requests? Then a chatbot is ideal. Do you perform visual quality controls? Computer vision can help. Do employees have trouble finding information? A RAG system is the solution. Contact us for a free analysis.

How long does implementation take?

It varies by use case. A simple chatbot can go live in 2-4 weeks. Computer vision projects need 6-12 weeks for training and integration. RAG systems are ready in 4-8 weeks, depending on document volume.

Can multiple use cases run on one server?

Yes, with sufficient GPU capacity. An AI Server Pro (RTX 6000 Blackwell Max-Q) can host multiple smaller models in parallel or use one large model for different tasks. We help with optimal sizing.

Should I use Ollama or vLLM?

It depends on your use case. Ollama is perfect for development, prototyping, and smaller deployments (up to ~50 concurrent users). It's very user-friendly and quick to set up. vLLM is ideal for production environments with high performance requirements: it offers up to 24x higher throughput than Ollama, lower latency, and better GPU utilization. Our recommendation: Start with Ollama for proof-of-concept, migrate to vLLM when going to production with high traffic expectations.

What happens to our data?

All data remains on your dedicated server in Germany. No transfer to third parties, no cloud APIs. Full GDPR compliance and data sovereignty.

Do we need AI expertise in our team?

Not necessarily. Our managed service includes setup, training, and maintenance of models. You only need someone to oversee the technical integration. For advanced customizations, we offer training.
