A2A's task model is designed for long-running scenarios: a task delegation produces a Task object with a unique ID whose state transitions among submitted, working, input-required, completed, failed and others, during which progress updates can be streamed via SSE, and push notification callbacks are also supported.

Unverified在典型的AI SaaS架构中，主流做法是客户端提交任务后立即获得任务ID，后端异步处理，处理完成后通过Webhook回调通知结果76% similarUnverifiedAsynchronous tool-calling mode allows the application layer to submit time-consuming operations for background execution while letting the model continue processing other subtasks that have no dependencies.76% similarUnverifiedUsing scheduler.yield(), setTimeout, or requestIdleCallback can split long tasks into multiple smaller tasks, yielding main thread control between tasks.73% similarUnverifiedIn the asynchronous task model, after `deepresearch.create()` sends the request the server immediately returns a task ID, and the actual research is queued and executed in the background; a wait timeout does not mean the task failed, and one should first query the status using the task ID rather than resending directly, because resending will create a new paid task and a duplicate report.72% similarVerified@ai-sdk/workflow provides a declarative API for describing directed task graphs, managing asynchronous call ordering, intermediate state passing, and error retry logic72% similar
