Factory

Assembling @droid, the frontier software development agent. Available to anyone, with any model, in any IDE/terminal.

Factory Router is a model routing layer that sits inside Factory's Droid coding agent, automatically picking which underlying model handles each session instead of leaving that choice to engineers. It targets enterprise engineering teams running Droid across coding, refactors, bug fixes, documentation, and investigation work, where defaulting every task to the most expensive frontier model has driven AI bills up without a matching lift in output. The launch matters now because token spend on coding agents has become a real line item for engineering orgs, and Factory is making the case that routing can hold quality steady while trimming roughly a quarter of that cost. According to Factory's own benchmarks, Factory Router cuts cost by 20-25% while pass rate holds at 99% of Opus on Terminal-Bench 2 and 96% on Legacy-Bench . It automatically selects the right model for each task and routes across providers if an endpoint degrades , with failover, reserved enterprise throughput, and US-hosted open-source options for teams that want a cheaper or more controlled path. Admins can also shape the routing policy with guidance about which workflows are routine and which need deeper reasoning, so the automatic selection reflects how a given org actually ships code. The product is shipping in private research preview. Factory was founded by Matan Grinberg and Eno Reyes , and the Sequoia-backed company has been building an enterprise-focused autonomous software engineering platform since 2023 , with Droid available across IDEs, the terminal, and CLI. Router slots in as the cost and reliability layer beneath that agent, useful for buyers evaluating how to scale agent usage across a large engineering team without writing a blank check to a single model provider.
