You can now chat with your running tasks. Input streams: send typed data INTO a @triggerdotdev task while it's executing. - Cancel signals for AI generations - Course-correct agents mid-run - Approval gates that free compute while they wait Shipped in v4.4.2 ↓

The pattern that unlocks everything: `𝚜𝚝𝚛𝚎𝚊𝚖.𝚘𝚗(𝚑𝚊𝚗𝚍𝚕𝚎𝚛)` Define a typed stream once. Listen for messages in the background while your task works. Your agent is researching. Your user types "actually, focus on pricing." The task picks it up mid-run and adjusts.

Cancel buttons, finally the easy way. Register a `.𝚘𝚗()` listener for a cancel stream. User clicks stop, you abort the @aisdk completion mid-stream. No polling. No external pubsub. No race conditions.

Need a human in the loop? `.𝚠𝚊𝚒𝚝()` suspends the task entirely. The process gets freed. Zero compute cost while it waits. Data lands, task resumes exactly where it left off. Timeout up to 7 days.

Send from React in a few lines. `𝚞𝚜𝚎𝙸𝚗𝚙𝚞𝚝𝚂𝚝𝚛𝚎𝚊𝚖𝚂𝚎𝚗𝚍` wires up any button, form, or chat input to a running task. Typed all the way from the click to the task.

Four ways to receive (`.𝚠𝚊𝚒𝚝`, `.𝚘𝚗`, `.𝚘𝚗𝚌𝚎`, `.𝚙𝚎𝚎𝚔`). Backend and frontend senders. All typed end to end. Read the full changelog here: trigger.dev/changelog/inpu…
