Factory launches Droid 1.0 coding-agent harness
Factory announced Droid 1.0, a model-independent coding-agent harness built around programmatic tool calling and an internal optimization loop. Factory says Droid outperformed native model harnesses on the same tasks with up to 20% greater efficiency, but the supplied report does not independently verify its benchmark, accuracy, or speed claims.
Droid 1.0 packages prompts, tools, result handling, and execution into a reusable harness designed to work across frontier models, including models for which users supply their own API keys.
Over the past year, we have worked with hundreds of thousands of developers across some of the largest enterprises in the world. Working side by side with these teams, we've built and hardened a frontier agent harness that directly meets the demands of enterprise development: high-quality results on complex tasks, efficient use of resources, and strong safety controls.
Today, we introduce Droid 1.0: more accurate, efficient, and faster than ever before, powered by new design principles and a programmatic tool-calling engine.
Droid is our agent harness. An agent harness is everything around the model: the prompts, the tools, how tool results come back, and the loop that runs it all. Agents now work for hours or days across hundreds of turns, and every turn re-sends instructions, tools, and history.
