A new programming model for durable execution

What this post added

This post announces the general availability of Vercel Workflows, a new programming model for durable execution. It details the architecture, which comprises an event log, Fluid compute for step execution, and Vercel Queues. The post highlights the programming model, where workflows and steps are defined using 'use workflow' and 'use step' directives in TypeScript and Python. It emphasizes the benefits for agents, including durable execution, tool calling, state management, and handling interruptions, as well as durable streams for persistent agent output. Security features like default encryption and audit trails are also detailed. The post also mentions the integration with AI SDK v7's WorkflowAgent and provides examples of its application in building agents and long-running workloads.
