Summary
An AI engineering commentary arguing that an AI app is far more than an LLM API call, breaking the stack down into compute/storage, serving, models, context, orchestration, agents, and experience layers — advising builders to start with hosted models and only add complexity as needed.

STOP THINKING AN AI APP IS JUST AN LLM API CALL.
THE MODEL IS ONLY ONE LAYER OF THE STACK.
Imagine you’re building an AI coding assistant.
Here’s what happens behind the scenes:
-
COMPUTE & STORAGE GPUs, cloud infrastructure, storage, and networking.
-
SERVING Run models through APIs, inference engines, or dedicated endpoints.
-
MODELS GPT, Claude, Gemini, open-weight models, and reasoning models.
-
CONTEXT Memory, retrieval, prompts, caching, and tool definitions.
-
ORCHESTRATION Connect models, tools, workflows, and agent loops.
-
AGENTS Plan tasks, write code, run tests, and iterate.
-
EXPERIENCE Chat UI, IDE integrations, voice, and apps.
Every layer solves a different problem.
Infrastructure powers the system.
Serving makes models available.
Models generate outputs.
Context provides relevant information.
Orchestration connects the components.
Agents execute multi-step tasks.
The experience layer brings everything to the user.
And here’s the engineering insight:
You don’t need to build every layer yourself.
Start with hosted models and managed infrastructure.
Add custom serving, memory, orchestration, or open-weight models when your requirements justify the complexity.
The goal isn’t to own the entire stack.
It’s to understand every layer well enough to know what to build, what to buy, and what to replace.

I drew the entire AI stack on one page... and it's mostly not models.
The author proposes a five-layer AI stack pyramid—foundations, data, models, agents, and applications—to argue that progress depends on more than just model capabilities. The article invites discussion on the placement of evaluation and interpretability within this architecture.
Most AI agents are just API calls with a loop around them
The author argues that AI agents are essentially API calls with loops, emphasizing that production success depends on defensive engineering like retries, timeouts, and human approval rather than model choice.
