Factory releases Droid 1.0 agent harness with programmatic tool calling
READ THE ORIGINAL SOURCEOpen original sourcefactory.com · Opens in a new tabFactory introduces Droid 1.0, an agent harness designed to work across many models rather than tuned to one. The post says Droid outperforms native harnesses on the same tasks, up to 20% more efficiently. Its central change is programmatic tool calling via a Script tool, where the model writes JavaScript that runs sandboxed tool calls, letting hundreds of calls run in one model request. Benchmark results on Terminal-Bench 4 are reported with cost-per-passed-task comparisons against Codex, OpenCode, Devin, Cursor and Claude Code.

A READER'S EVIDENCE CHECKHow to read this signalSix questions about claims, sources, risks, and open checks
This is a signal-level guide until claim-level evidence is available. “Not recorded” means the evidence has not been assessed here; it does not mean a result is false. How we check AI news →
- 01Who is making each claim?
The claimant and whether each claim was measured or asserted are not recorded in this public brief.
- 02What was actually tested?
Not recorded per claim. Check the source for sample size, tasks, model and benchmark versions, and reproducibility.
- 03Where are the sources?
Original link: factory.com. Brief basis: fetched source page. Primary page date and quote locations are not established in this panel.
- 04What could mislead?
Benchmark and cost figures are vendor-reported on Factory's own methodology; source claims not independently checked.
- 05What is at risk if wrong?
Not assessed per claim. Consider safety, privacy, cost, and adoption decisions before relying on the result.
- 06What would change the view?
No claim-specific check is recorded. An inspectable primary method or independent replication could change the assessment.
Key findings from the stored brief
- Droid 1.0 is reported to outperform native harnesses built for their models up to 20% more efficiently on the same tasks.
- Programmatic tool calling lets the model write a sandboxed JavaScript Script that can make hundreds of tool calls in one model request.
- On Terminal-Bench 4, Droid reports $0.79 cost per passed task with 57.6% pass rate using GPT-6.1 Sol.
- Factory says it tunes prompts and tool descriptions per supported model and tests changes across every affected model family.

Factory released Droid 1.0, a rebuilt agent harness in which the model can write code that runs hundreds of tool calls in one model request. Factory says Droid outperforms the native harnesses built for each model, up to 20% more efficiently, on the same tasks; these are Factory's own benchmark results.

Timeline & updates
- Signal dated by source or discovery feed
This timestamp places the signal in the radar. It may be the discovery post date rather than the primary page's first publication date.
- Shared brief stored
AINewsIQ prepared one abstract from fetched source page.
A publication revision history is not stored for this signal. New engagement snapshots do not mean the source itself changed.
Why this may matter
If the efficiency gains hold, running many tool calls inside one program could lower cost and context growth for long-running enterprise coding agents. Model-independent tuning also aims to separate general harness improvements from single-model quirks.
Limits and open questions
Benchmark and cost figures are vendor-reported on Factory's own methodology; source claims not independently checked.
Organization-specific financial, security, and operational effects require the organization's own context and review.
