This has been insanely fun to work on for the past couple weeks!

This rewrite tested the limits of all our products: thousands of subagents via Prime Agent, billions of tokens via Prime Inference, and hundreds of sandboxes via Prime Sandboxes!

It's incredibly rewarding to see our full stack come together, and Prime Agent is now faster than ever :)

I want to make the @vercel CLI 100x better.

What flows and functionalities do you want to see improved?

MCP is exploding

You can now create new web apps with Cursor, store the code with Origin, and deploy to Vercel.

Vercel MCP now supports the latest MCP spec:

▪️ Stateless requests
▪️ OAuth 2.1 authorization

It predicts future states and uses CEM to control Mario over short horizons.

Based on LeWorldModel by @lucasmaes_.
