Vercel AI Updates: June 26, 2026

1. AI SDK 7 Turns the Library Into a Full Agent Platform

Vercel released AI SDK 7, a major version that shifts the library from basic model calls toward a complete agent platform with production-ready agent capabilities. The release adds reasoning control, tool and runtime context, provider file uploads, MCP Apps support, tool approvals, and durable agent execution through a WorkflowAgent that supports timeouts and resumable runs. Observability is rebuilt around redesigned telemetry with OpenTelemetry integration, and the upgrade is ESM-only with a Node.js 22 minimum, so existing projects will need a migration pass. Source

2. Vercel Details How It Teaches Coding Agents Its Product Design Standards

Vercel published a framework for encoding product decisions into agent-accessible skills so coding agents follow a team’s design conventions rather than improvising. The approach pairs written agent guidance with deterministic linters and evidence-based review workflows, combining soft instruction with hard enforcement so agents are both directed and checked. Vercel frames it as a reusable pattern other teams can adopt to make agent output consistent with their own standards. Source

3. Deep Agents and OpenCode Join the AI SDK Harness

Vercel added Deep Agents and OpenCode as new adapters in the AI SDK Harness, the abstraction that lets different coding-agent runtimes plug into the SDK’s unified interface. The additions bring the number of supported harness runtimes to five, giving developers more interchangeable options for the agent loop behind their applications. The move reinforces AI SDK 7’s positioning around durable, swappable agent execution rather than a single fixed runtime. Source
