DeepSeek-V3's reported $5.6 million training cost reshaped the conversation about frontier AI, but it covers only the final run, not the research and failed experiments behind it. This piece breaks down what AI development really costs, how MoE, MLA, FP8 training, and hardware-software co-design drove DeepSeek's efficiency, where open models still trail closed ones, and why the distillation controversy complicates the story.

This comprehensive guide uses a martial-arts belt analogy to outline the path to AI mastery -from a beginner White Belt (AI User) all the way to an expert Black Belt (AI Architect). Each belt level represents a milestone in skills, tools, and mindset. We detail what you can do at each stage, example projects, checklists to level up, recommended resources (including a highly-rated Udemy course on AI Engineering), and time estimates for advancement. Whether you’re a newcomer or an experienced developer, you’ll see how to progress step-by-step.

Propagated.ai supports this journey by letting you select your belt level and preferred content type (technical guides, business case studies, news, tips, tutorials, etc.) to get personalized AI content and learning support tailored to your needs. Let’s begin the journey!
