Plow Latch is a Mac app that hands Claude.ai or Codex a real browser and command line on your machine. A second model sits in front of your credentials and decides what each agent gets to touch. Sam Odio is so confident in it, that he put his own Mac on Twitch and let the internet drive it: drop a comment telling the AI what to do, and watch it happen. Someone tried to sweet-talk the DoorDash password out of it but the AI said nope and so far it has bought at least two beefy burritos.

fx is Vercel's coding agent and the whole thing is 6MB, smaller than the photo you took this morning. It cold starts in ten microseconds. Written in Zig, no runtime to install, happy with local or cloud models, and it behaves like a Unix tool rather than another IDE squatting in your terminal. Coding agents have spent the year getting fatter, and every tool they bundle costs you context window before you've asked for anything. Vercel Labs open sourced it last week under Apache 2.0.

Router is one endpoint in front of every big model, open and closed, picking the cheapest one that still clears your quality bar. Ramp says teams save about 40%. Which is a funny place for Ramp to end up, since its actual job is corporate cards and nagging companies about overspending, and this is that same instinct pointed at tokens: spend mapped back to teams and budgets like any other bill. Stripe bought OpenRouter for over $7 billion five days ago, so that's two finance companies in a week deciding the token layer is theirs.
