Vercel changelog: Sandbox up to 24h, Passport public beta, Connect for agents, GLM 5.2 on AI Gateway

What's new

• Sandbox runtime up to 24h (Jun 16): up from a 6-hour limit – helps long-running agents and batch jobs.
• Vercel Passport public beta (Jun 17): unified identity layer for AI agents and traditional apps.
• Vercel Connect (Jun 17): securely scoped credentials letting an agent call external services without API keys in code.
• CLI deployment limits removed (Jun 17): the hard cap on CLI deploys is gone.
• GLM 5.2 on AI Gateway (Jun 16): Z.ai's open model now routable alongside Claude/GPT through the same gateway.
• Workflow SDK (Jun 16): added inflight cancellation and TanStack Start support.

Why it matters

Vercel has openly pitched itself as 'Next.js for agents'. These pieces (Sandbox, Passport, Connect) are the underlying infra on which the eve framework runs – arguably more important than the framework itself when you actually ship an agentic product.

How to try it

Passport and Connect are toggled in vercel.com project settings; the Sandbox 24h limit is live automatically for existing projects.
