Applied AI

AI that ships, not AI that demos.

What actually works when you put machine intelligence into a real product or workflow — evaluation, cost, latency, failure modes, and the org design around it. Written by someone who builds with these systems, not just about them.

The Jagged Frontier: AI Is Superhuman and Subhuman at the Same Time

AI capability isn't one number climbing toward "human level." It's a jagged frontier — superhuman at some tasks, worse than a child at others, with no smooth link between them — and that jaggedness, not the average, is what makes deployment hard and "AGI" a category error.

Your Feed Is an Agent-vs-Agent War, and You Are the Prize

Your feed is now a contest between the platform's recommender optimizing your engagement and a swarm of AI generators optimizing to be recommended. Neither has your interest in its objective. The fix is a third agent that does.

The Founder's Field Guide to Shipping AI That Works

The end-to-end playbook for deploying AI in a real business: find the high-leverage use case, build the eval before the feature, design the human-in-the-loop, and measure ROI honestly enough to decide scale, iterate, or kill.

You Can't Evaluate an Agent You Can't Specify

Enterprise agent pilots stall at "impressive demo, never shipped" because teams score final answers while agents operate on trajectories — path-dependent decision sequences where one demo tells you almost nothing.

Software Is About to Lose Its Interface

A GUI is a translation layer between human intent and machine state. When an agent is the user, that translation is overhead — so for whole software categories the callable capability becomes the product and the screen goes vestigial.

Hallucination Is What Next-Token Prediction Rewards

LLM hallucination isn't a bug to patch. Truth is not a term in the training objective, so a fluent, confident falsehood is exactly what the loss rewards when the true continuation is uncertain.

The Agent-to-Agent Economy Runs on Rails the Web Never Built

The consequential shift isn't agents running your errands, it's agents transacting with other agents. That needs identity, binding commitment, and settlement primitives the web never built, and it opens an adversarial surface it has never faced.

Agent Memory Is the Next Bottleneck

Today's agents are amnesiacs that re-solve your problem from scratch every session. The next advance isn't a smarter model but persistent, structured memory, and the accumulated record of working with you is where the real moat forms.

World Models: Why the Next Leap May Not Be a Bigger LLM

A serious research line bets the path past current limits is not a larger language model but a world model — a system that learns an environment's dynamics so it can simulate, plan, and reason about interventions. A live bet, not a proven result.

Use One Agent Until the Task's Structure Forces You to Add Another

Every extra agent buys you coordination overhead and a new error surface. A multi-agent design earns its keep only when the task has a structure one agent can't serve: parallel work, independent verification, real role separation, or a chain too long to run reliably in one pass.

The Best Multi-Agent Design Is a Debate

The multi-agent setups that catch errors are adversarial, not cooperative: debate, generator-versus-critic, independent-then-vote. Agreement between correlated agents is worth almost nothing; the game is uncorrelated errors and a real judge.

AlphaFold Was the Exception, Not the Template

AlphaFold worked because protein folding met four rare conditions most scientific problems don't. Score your problem on them before betting on "AlphaFold for X" — or get confident wrong answers faster.
