Agent Mesh vs Supervisor: What Holds Up in Production

Open agent meshes lost to bounded supervisor patterns in 2026 production data — the failure surface grows as agent-pairs, not agents, and the token bill grows with it. Here's the data, why Gartner's "context mesh" is a different idea entirely, and the narrow cases where a controlled mesh still wins.

Two Python-agent series. They’re not a choice — they’re a sequence.

Start with Foundations if you’re new — build an agent by hand, no framework. Move to Production once the basics click. Pick by where you are right now.

1Level 1Foundations — build it by hand
2Level 2Production — ship a real one

01Beginner · Foundations

AI Agents from Scratch in Python

Build a working agent with nothing but Python and one LLM call — no frameworks, so you actually understand the loop.

Start here if you…
are new to agents, or want to know how one actually works before reaching for a framework.
Length
6 parts (00–05)
Approach
Pure Python + a raw LLM call
Prereq
Can read basic Python (Part 0 teaches it)
You'll build
Your own agent loop — tools, reasoning, memory — by hand
Start Part 00 — Python basics →
02Intermediate · Production

Agentic AI in Python: Zero to Production

Take a real agent all the way to a deployed, observable service using LangGraph — state, tools, memory, and shipping.

Start here if you…
already get the basics (or finished Level 1) and want to ship something production-grade.
Length
7 parts (01–07)
Approach
LangGraph + deploy & observability
Prereq
Comfortable with agent fundamentals
You'll build
A real agentic app, deployed as an observable service
Start Part 01 — first build →

One is an AI code editor you drive; the other is a terminal agent that drives itself. Here's how they differ on workflow, pricing, and token efficiency — and why the real answer is often "both."Sukhveer Kaur · Jun 27, 2026
