Claude Code Projects rebuilt around a coordinator that directs parallel threads, with per-thread model and thinking-effort settings
Anthropic released a redesigned Projects beta on 2026-09-17 in which a project is a coordinator chat plus worker threads: Claude scopes the request, delegates, coordinates parallel threads over shared memory and a common file library, reviews outputs and assembles the result, and work continues in the cloud after you step away. The coordinator and each worker thread take independently selected models and thinking-effort levels, which is the direct lever on token spend. Beta went first to Pro and Max subscribers who already use cloud sessions and have no existing web or desktop projects, widening over the following week.
