Dynamic Workflows.

Dynamic Workflows is an Anthropic feature that takes one big job, splits it across a bunch of Subagents that run at the same time, then stitches all the results back together.

Instead of one agent grinding through a huge task step by step, the work gets fanned out. Ten smaller workers go at once, each handles a piece, and you get the finished thing assembled at the end. For anything that breaks cleanly into parallel chunks, like research across twenty sources or processing a big batch of files, it's fast.

The catch is Tokens. Every one of those subagents is reading context and doing its own thinking, so you're paying for ten brains instead of one. It's powerful, but it's hungry. I reach for it when a job is big enough that the speed is worth the spend, and I leave it alone for small stuff a single agent handles fine.
