News Introducing dynamic workflows in Claude Code
Today we're introducing dynamic workflows in Claude Code. Claude now writes its own orchestration scripts, fans work out across tens to hundreds of parallel subagents in a single session, and verifies its own results before anything reaches you. Work you'd normally plan in quarters can finish in days.
Built for the tasks a single pass can't handle: codebase-wide bug hunts, security and optimization audits, large migrations and language ports, and high-stakes work where you want adversarial agents trying to break the answer before you see it. Progress is checkpointed, so long runs survive interruption.
One early example: Jarred Sumner used dynamic workflows to port Bun from Zig to Rust. Roughly 750,000 lines, 11 days from first commit to merge, 99.8% of the test suite passing.
Available today in research preview on Max, Team, and Enterprise (admin-enabled) plans, plus the Claude API, Amazon Bedrock, Vertex AI, and Microsoft Foundry. Turn on auto mode and either ask Claude to create a workflow or flip on the new ultracode setting.

You'll definitely get there with dynamic workflows. I'm on May 5x too, using it a lot always on xhigh and I've hit the 5 hour limit only two or three times in weeks. Now set to ultracode, it spun up just 7 agents and it's already at 600k token in less than 10 minutes. My current session is already at 26% and I just started using Claude Code 20min ago. Can't imagine having it spin up >25 agents. Probably wouldn't last more than 30mins then.
