Factory ships Droid 1.0 with programmatic tool calling as the default
What happened
On October 29, Factory released Droid 1.0, an enterprise AI agent harness built around programmatic tool calling, and made that mode the default for several models. It also updated the desktop app, CLI and Droid SDK. The Script tool lets a model write JavaScript in a sandbox and run hundreds of tool calls inside one model request, passing only needed output into context. Factory's tests show Droid on Claude Opus 5.5 cut costs by 15% in this mode.
