✅ What is a Custom AI Model?

A custom AI model is a machine learning or deep learning model trained to solve a specific problem for a specific organization using relevant, often proprietary data.

Unlike generic AI tools, a custom model delivers:

  • 🎯 Higher accuracy
  • 🧠 Better domain understanding
  • 🔒 Data privacy and control
  • ⚙️ Better integration with internal systems

🚀 Why Build Custom AI Instead of Using Pre-Trained Tools?

Generic AI ToolsCustom AI Model
Trained on public dataTrained on your internal data
Limited contextDeep domain-specific understanding
Hard to fine-tuneFully controllable + adaptable
No ownershipFull IP ownership & flexibility

Custom AI = Competitive Advantage


🌏 Why Vietnam for Custom AI Development?

Vietnam is a rising star in the global AI market, thanks to:

  • 🧠 Talented data scientists and ML engineers
  • 💸 Affordable rates ($15–25/hour)
  • 🌐 Experience with offshore collaboration (EN/JP)
  • 🚀 Fast prototyping and turnaround time

💡 Companies like NKKTech Global deliver enterprise-grade AI models with global scalability.


🏆 How NKKTech Global Builds Custom AI Models – Step by Step

Phase 1: 🔍 Requirement Analysis & Use Case Design

  • Define AI objective (classification? prediction? recommendation?)
  • Identify KPIs and success metrics
  • Determine available & missing data

Phase 2: 📊 Data Strategy & Collection

  • Gather internal documents, logs, images, or audio
  • Apply OCR, labeling tools, or RPA if needed
  • Ensure data cleaning, structuring, anonymization

Phase 3: 🧠 Model Design & Training

  • Choose model type: classification, regression, NER, NLP, etc.
  • Fine-tune LLMs (e.g. GPT, LLaMA, Claude) or build from scratch
  • Tools: PyTorch, TensorFlow, HuggingFace, OpenAI APIs

Phase 4: 🧪 Validation & Evaluation

  • Run benchmark tests
  • Measure accuracy, precision, recall, latency
  • Compare models and select best-performing one

Phase 5: 🚀 Deployment & Monitoring

  • Expose via API (FastAPI, Flask, NodeJS)
  • Host on AWS, GCP, or private server
  • Set up retraining, model drift alerts, logging
