Understand the four layers of the AI agent stack. See the same agent built three different ways and find the abstraction level that fits your needs.
Stack Layer Explorer
Click each layer of the stack to see what it provides, its trade-offs, and which platforms sit at that level.
Select a layer above to explore
Maximum Control
Maximum Convenience
Raw API: Full control, you handle everything
Code Comparison Viewer
The same research agent (searches the web, summarises results) built three ways. Switch tabs to compare the code at each abstraction level.
Key insight: Start at the highest abstraction that meets your requirements, then drop down only when you hit limits. Most teams never need the raw API layer.
Trade-Off Analyser
Rate your priorities and get a recommended abstraction layer.
Adjust the sliders above to see your recommendation.
