By November 2025, the scientific computing stack (NumPy, Pandas, SciPy) has achieved full ABI compatibility with the free-threaded build. This paper benchmarks a matrix multiplication task using NumPy 2.3 on Python 3.13.1, demonstrating a on 8-core systems compared to the GIL-enabled baseline, validating the promise of free-threading for data-heavy workloads.
