The Analogy That Unlocks It
In the 2000s, software decomposed. You didn't build your own email server; you used a SaaS product. You didn't manage your own compute; you used a cloud provider.
AI systems are at the same inflection point.
The Five Layers
Retrieval — how the system accesses knowledge Orchestration — how the system coordinates work Reasoning — where inference happens Analytics — how the system understands itself Social — how the system interfaces with communities
Each layer is independently buildable, deployable, and scalable.
Why Monoliths Fail
Monolithic AI systems couple retrieval, reasoning, and output into one surface. When the retrieval layer breaks, the whole system breaks. When you want to scale inference, you scale everything.
SAAL decouples this. Teams own layers. Layers have contracts. Failures don't cascade.
