AI engineering, agentic systems, and what they mean for founders and operators.
Route 80% of Agent Calls to a Local Model and Cut Your LLM Bill
_By the end of this, you will have a routing architecture with one quality gate. It pushes the easy 80% of agent calls to a local model and escalates only the hard 20% to a frontier API. Your output quality stays flat.…
Your Agent Pipeline Stalls at Layer 4 — Here's What Layers 5–9 Actually Do
Most agent pipelines top out at four layers and survive a hackathon, not a week of production. Here are the five layers — failure recovery, supervisor routing, source ledger, audit log, render-budget lock — that make the harness production-safe.
Your Agent Pipeline Stalls at Layer 4 — Here's What Layers 5-9 Actually Do
_Walk through all nine layers of a production agentic harness. See exactly where layer 4 teams plateau, what failure recovery, supervisor routing, source ledger, audit logging, and render-budget locking each contribute,…
Four Questions to Pick Your 2026 Agent Harness — and Three Gaps None of Them Fill
_Run four questions against any agent harness candidate and you will know whether it survives production. Then audit three primitives — source verification, a 30-day human gate, a hash-chained audit log — that no curren…
Your Agentic Supervisor Pattern Is Causing the Timeouts — Fix It With Gemini Webhooks
_Gemini API just shipped event-driven webhooks for long-running jobs. Stay for the next ten minutes and you will walk away with a concrete supervisor pattern switch — polling out, webhooks in — that stops cascading time…
Kill the Polling Loop: Gemini Webhooks and the Supervisor Pattern That Replaced It
_Google's Gemini API now ships event-driven webhooks for long-running jobs. That makes the polling-loop supervisor pattern obsolete. Walk away knowing exactly what breaks with polling, what webhooks change architectural…
Gemini Webhooks Are Live — Rebuild Your Supervisor Pattern Before You Scale
_Gemini just shipped event-driven webhooks for long-running jobs. That changes which supervisor pattern you should be running. Stick around — by the end you'll know exactly which architecture to scrap and which one to r…
Drop the Polling Loop: Gemini Webhooks Fix Your Silent Retry Problem
_Gemini's API just shipped event-driven webhooks for long-running jobs. That changes the architecture equation for every founder running agentic workflows at scale. Walk away knowing exactly why your supervisor pattern…
Gemini API Webhooks: Drop the Polling Loop on Long-Running AI Jobs
_Gemini API now ships event-driven webhooks. Swap your polling loop for a webhook endpoint in three steps — cut latency, drop wasted compute cycles, and keep your core stack intact. No rewrite required._
The Source Verification Playbook: Stopping AI Hallucinations Before Publish
Four deterministic checks plus an LLM tiebreak. The 0.8 confidence floor that keeps the bundle from shipping with a fabricated stat.
Cost-Aware LLM Deployment: Avoiding the $10k Surprise Bill
Three patterns that keep the monthly bill under $200/mo while still using frontier models where they earn it.
AI Agent Loop Architecture: When to Use ReAct vs. Plan-Execute vs. Reflexion
Three loop shapes power most production agents in 2026. Picking the wrong one wastes 5x the tokens. Here is how to choose.
Context Windows, Explained for Operators
Why a 1M-token context window is not the win you think it is — and what to do instead.
