# Edison Scientific's Kosmos AI scientist claims six months of research per run

In early November 2025 FutureHouse spin-out Edison Scientific launched Kosmos, an autonomous AI scientist that reads ~1,500 papers and runs ~42,000 lines of analysis code per 12-hour run; beta users estimated one run equals ~6 months of their work, and 79.4% of its statements were judged accurate. It reported 7 discoveries, 3 reproducing unpublished findings.

## Key facts
- Typical run: 12 hours, ~1,500 papers read, ~42,000 lines of code executed (structured 'world model' shared across agents)
- 79.4% of conclusions judged accurate by independent scientists
- 7 discoveries across metabolomics, materials, neuroscience, genetics: 3 reproduced unpublished/preprint findings, 4 presented as novel
- '6 months of work in one day' is a beta-user estimate, not an independent measurement

## What happened

Kosmos runs many parallel literature-search and data-analysis agents coordinated through a shared structured world model, producing reports in which every statement is traced to code or a paper.

## Why it matters

It is an early commercial "AI scientist" whose headline value is reproducing months-long analyses overnight. The strongest evidence is that it independently reached conclusions matching unpublished human work.

## What is disputed or not yet verified

- Verification: Preprint (arXiv 2511.02824); accuracy assessed by independent scientists hired by the company
