Python 3.13 Gets a JIT
Summary: Python 3.13 introduces a Just-In-Time (JIT) compiler, a significant change to the CPython interpreter. The new JIT, called copy-and-patch, improves performance by 2-9% in initial benchmarks. It works by generating machine-code templates for Python bytecodes, which are then stitched together and patched at runtime. This approach is less complex and resource-intensive than a full JIT compiler, making it more suitable for average Python users. The JIT compiler lays the foundation for further optimizations in future Python versions.
