Structured learning guide | DataGate.ch Knowledge Base
This learning path takes you from AI fundamentals to production-ready skills. Each step builds on the previous one. Follow the recommended order for the most effective learning journey.
Phase 1: Foundation
Start here if you’re new to AI/LLMs. These concepts underpin everything else.
How text becomes numbers. Understanding tokenization helps you control costs, avoid bugs, and optimize your prompts.
How AI represents meaning mathematically. Essential for understanding RAG, search, and semantic similarity.
The engine that powers every modern AI model. Understanding attention is understanding modern AI itself.
Phase 2: Working with LLMs
Practical skills for getting the best results from language models.
Control the creativity vs accuracy tradeoff. Essential for tuning model output to your specific use case.
The hidden instructions that shape AI behavior. A well-crafted system prompt is the foundation of any AI application.
The single most impactful prompting technique. Dramatically improves reasoning quality for complex tasks.
Understanding the model’s working memory. Critical for building applications that handle long documents or conversations.
Phase 3: Production AI
Advanced topics for deploying and maintaining AI systems.
Why models make things up and how to prevent it. The #1 risk in production AI systems.
Adapting models to your specific domain. When prompts aren’t enough, fine-tuning delivers specialized behavior.
Running AI on less hardware. The key technique for cost-effective local deployment.
Beyond the Basics
