Real AI apps follow layers:

🧱 Layer 1 — API

Endpoints, auth, rate limits, logging.

🧠 Layer 2 — Model layer

Different models for:

• generation
• embedding
• classification
• planning

🛠️ Layer 3 — Tools

Tools give the model superpowers:

• SQL
• scrapers
• Telegram
• HTTP
• Python execution

📚 Layer 4 — Memory

• vector store
• cache
• database
• logs

🔁 Layer 5 — Task engine

Manages planning, retries, timeouts, and structured output.

👁️ Layer 6 — Observability

Logs, traces, metrics.

🎨 Layer 7 — UI

CLI, Flask, React, Telegram — doesn't matter.
UI is not the app.

🐸 GhostFrog example

GhostFrog already uses:

• scrapers
• models
• ROI logic
• logs
• Telegram delivery
• Postgres pipelines

This is real architecture — not a toy.
