Creditizens is a YouTube channel about building small, reliable AI systems.

We focus on AI systems engineering for builders and developers who want to design, ship, and debug real AI architectures. The channel covers AI system design, AI agents, RAG systems (Retrieval-Augmented Generation), glue code, orchestration, local AI experiments, and DevOps for AI systems.

Topics include:

• How to build reliable AI agents
• How to design and debug RAG systems
• AI architecture breakdowns
• Minimal AI stacks for real products
• Monitoring and operating AI systems in production
• Glue code and orchestration patterns
• Experimenting with local AI models
• Comparing AI agent frameworks
• Practical AI engineering tutorials

The goal is to help builders understand how AI systems actually work — from foundations to production.

We follow the AI Systems Ladder:
foundations → glue code → RAG → agents → operations.
