Physicist Schwartz Releases BootLoops 1.0, an Open-Source LLM Harness for Science

Theoretical physicist Matthew Schwartz published BootLoops 1.0 under the MIT License, an open-source Claude-based toolkit for exact calculations in quantitative science. In three months the project produced 36 manuscripts across 18 fields, including 15 previously uncomputed elliptic Feynman integrals and an analysis of 5.7 billion mutation pairs.

• BootLoops 1.0 was released on October 1, 2026 under the MIT License
• The toolkit computed 30 integrals, 15 of them for the first time
• The project yielded 36 manuscripts across 18 fields with 19 coauthors in three months
• An analysis of 4,452 replication packages found discrepancies in 3,460 articles
