Factory's Droid 1.0 harness lets a model run hundreds of tool calls in one request, and beats native harnesses on Factory's own Terminal-Bench 4 runs

Factory released Droid 1.0 on October 29. It's a model-independent coding agent harness with a new Script mode: the model writes JavaScript that runs in a sandbox and can make hundreds of tool calls in a single model request, instead of one request per call. In Factory's own Terminal-Bench 4 runs (October 23 to 28, three trials per task), Droid passed 65.2% of tasks with Claude Opus 5.5 at $4.73 per passed task, against 57.6% for Claude Code. With GPT-6.1 Sol it passed 57.6%, against 54.0% for Codex, at 12% lower cost. These are vendor-reported numbers, and Factory's methodology lists reruns and scoring adjustments. Droid 1.0 ships as a desktop app for macOS and Windows and as a terminal UI.
