Vercel AI Updates: July 19, 2026

1. Vercel Sandbox Drops Charges for Downloaded Data

Vercel. Vercel stopped charging for data that Vercel Sandbox downloads from the internet, so installing packages, cloning a Git repository, or pulling artifacts no longer incurs data transfer costs. Sandbox is the isolated compute environment Vercel uses to run untrusted or agent-generated code, and the change lowers the cost of setup-heavy agent and build workloads. Inbound traffic on exposed ports and outbound traffic from the sandbox remain billable. Source

2. Vercel Plugin Arrives in the Kimi Code CLI

Vercel. Vercel made its Vercel Plugin available in Moonshot AI’s Kimi Code CLI, giving the AI coding assistant platform knowledge and skills for Next.js, the AI SDK, and Vercel Functions. The integration lets the CLI agent reference Vercel-specific guidance while generating and editing code. It extends Vercel’s plugin distribution beyond its own tooling into a third-party agentic CLI.

3. Vercel Optimizes CDN Caching for Immutable Static Assets

Vercel. Vercel now reuses content-addressed static files across deployments instead of re-uploading and re-caching them each time. For frameworks that use Skew Protection, the company reports 17 percent fewer CDN requests and 24 percent fewer bytes served, along with faster deployments and improved time to first byte. The optimization applies to immutable assets whose contents determine their identity. Source
