Multi-agent AI systems need control planes to separate agent recommendations from execution authority, policy enforcement, and auditability.

Multi-agent systems do not fail like normal software; they can coordinate into bad decisions without crashing. Orchestration only routes agents and tools, while a control plane decides whether an action is allowed before it executes. For enterprise AI, agents should propose actions, but policy, state checks, and deterministic controls must approve them.

Model Context Protocol (MCP) lets AI discover and use new tools on the fly. Each MCP server becomes a domain-specific intelligence hub that can serve multiple agents while maintaining its own security and business logic.

AI has broken the software model where we launch a software tool and get billions of dollars (and people) nearly freely. Now, like in particle physics, a considerable investment of energy must be made before we ROI. This energy shall only be profitable if it is everywhere hence cheaply owned by the people.

Cost per token is a misleading AI metric. Learn why total cost per successful task determines the cheapest model and how to optimize LLM routing.

Cost per token is only the visible cost of AI. The real metric is cost per successful task, which includes human rework. A more expensive frontier model can be cheaper overall if it significantly reduces failures. This article introduces a simple equation to decide when paying more for a model actually saves money.

SHAP attribution accuracy is the wrong metric for regulated AI. σ_SHAP — variance across K rotated background samples — is the defensible alternative.

An adversarial explainer can choose a background dataset that makes the same model justify two opposite decisions. Attribution accuracy is not the goal — attribution stability is. σ_SHAP, measured across K rotated background samples, gives you a variance bound you can defend under regulatory challenge. Single-shot SHAP cannot.

My agent had no idea what I did all day. I compiled 55 days of screen capture into episodic memory it can read: 88x fewer tokens, 68ms per day, no LLM.

AI agents remember conversations but not what their user actually did all day. I compiled 55 days of my own screen capture into activity frames (bounded episodes with apps, pages, durations, input counts) using deterministic code, no LLM in the pipeline. One day of raw capture is 126,812 tokens; the compiled context block is 1,441 (88x smaller), builds in 68ms, and is byte-identical across runs. The schema keeps measured facts and inferred labels in separate tiers so memory stays auditable. Open-source implementation with an MCP server included.
