Meet Factory Droid 1.0: A Model-Independent Coding Agent Harness Built on Script Mode

Factory released Droid 1.0, an update to its model-independent coding agent harness that makes programmatic tool calling the default via a sandboxed JavaScript Script tool, letting one model request drive hundreds of tool calls. Factory reports a 65.2% pass rate on Terminal-Bench 4 with Claude Opus 5.5 at $4.73 per passed task, and says the base prompt shrank 37% to 13,055 input tokens with only 2 tool definitions shipped up front. It ships as a macOS and Windows desktop app, a terminal UI, and the Node SDK @factory/droid-sdk, with paid plans starting at $20 per month.
