## Summary

Factory has rolled out Droid 1.0, the largest update to its Droid agent harness. The update makes programmatic tool calling the default, letting a single model request drive hundreds of tool calls. The base prompt shrank to 13,055 tokens, a 37 % reduction from the previous 20,887, and only two tool definitions ship up front.

Performance data from Factory’s own tests shows Droid 1.0 achieving a 65.2 % pass rate on Terminal‑Bench 4 with Claude Opus 5.5, at $4.73 per passed task, and a 57.6 % rate on GPT‑6.1 Sol at $0.79 per passed task. The harness also reports lower costs and faster execution on Opus 5.5, cutting time by 16‑26 % per passed task and using 17 % fewer tokens versus other harnesses.

The update includes a leaner first request, a prompt cache that reads 98 % of input from cache, bounded autonomy limits, and a 488 ms first‑paint latency. Paid plans start at $20 per month, and the SDK is available on macOS, Windows, terminal UI, and Node via @factory/droid-sdk.

## Key points

- factory releases droid 1.0, making programmatic tool calling default
- base prompt shrank 37 % to 13,055 tokens, only two tool definitions ship
- droid 1.0 scores 65.2 % on terminal‑bench 4 with Claude Opus 5.5

## Why it matters

The update streamlines coding‑agent workflows, reducing prompt size and tool calls while improving speed and cost. Developers can run more complex tool chains in a single request, potentially lowering infrastructure spend and accelerating AI‑driven code generation.
