What you get
Four sections. Every morning.
Signal of the day
The single most important thing that happened in AI today. Coverage across OpenAI, Anthropic, Google, Meta, and 50+ agent startups, with source links on every claim.
One tactical play
A concrete action you can execute today. Not theory. Working code snippets, integration recipes, and architecture decisions for builders.
Classified
The section nobody else runs. Early signals, unreleased benchmarks, and moves being made behind closed doors. Context you can act on before it hits the timeline.
Quick hits
Three to four bullet-point signals to scan in seconds. No sponsors. No ads. Every claim sourced. Three minutes, then back to building.
Sample issue
Here’s what it looks like.
Frontier
March 7, 2026
Signal of the day
Apple released Foundation Models at WWDC 25 — a free, on-device LLM with tool calling at 30 tokens/sec. No API key. No cloud dependency. First time a major platform bundled a capable LLM at the OS level with zero marginal cost.
One tactical play
Use Apple Foundation Models as a free intent router in front of your expensive API calls. Simple intents handled locally, complex ones forwarded to Claude. Cuts API bills 40-60% on a typical assistant app.
Classified
Three infrastructure companies quietly testing agent-native pricing — per-action-completed, not per-token. One is live in private beta. The arbitrage window closes in weeks, not months.
