Introducing SSE for Task Runs

Server-Sent Events (SSE) for Task Runs, now in beta, offers real-time visibility for long-running web research tasks through the Parallel Task API, providing users with live progress updates, model reasoning, and status changes without the need for polling. This capability enhances user interfaces for production applications by delivering granular updates, thus improving user experience for AI assistants, research dashboards, and interactive workflows. Previously, SSE supported Task Groups, but this update extends it to individual task runs, offering detailed insights into each task's execution state. Users can establish an SSE connection using a run ID to receive continuous JSON-formatted updates, which include progress statistics, model reasoning, status changes, and error details. This system enables precise UI updates and allows users to see the ongoing process during complex web research operations, rather than waiting for final results. SSE for Task Runs is designed for production applications, ensuring transparency and responsiveness during lengthy operations, and is now available across all Parallel Task API processors for integration into applications.
