   When CPython is configured and built using the :option:`!--enable-experimental-jit` option, a just-in-time (JIT) compiler is added which may speed up some Python programs. On Windows, use PCbuild/build.bat --experimental-jit to enable the JIT or --experimental-jit-interpreter to enable the Tier 2 interpreter.

   Oct 7, 2024 · Andrew Cornwall, an analyst at Forrester Research, agrees that the two most significant runtime changes in Python 3.13 are experimental, “so everyday CPython users won’t see much difference yet,” he told The New Stack. However, Python is laying the groundwork for faster code running on multiple processors. “A JIT compiler should make ...

   Oct 23, 2012 · To answer the question you meant to ask: CPython, 3.x or otherwise, does not, never did, and likely never will, contain a JIT compiler. Some other Python implementations (PyPy natively, Jython and IronPython by re-using JIT compilers for the virtual machines they build on) do have a JIT compiler.

   Does Python 313 have a JIT compiler?

   • Python 3.13 brings two experimental features that open the gateway to much better performance in future releases. These groundbreaking changes will require thorough testing, which is why they’re not currently enabled by default. However, you can try out free threading and the JIT compiler today by building Python from source code.

   How to enable free threading & JIT compiler in Python?

   • Navigate into the parent folder containing the Python source code, which you extracted from the downloaded archive in the previous step: Make sure to adjust the path as necessary if you opted for a more recent Python 3.13 release. Now, you can run the configure script with custom build flags to enable free threading and the JIT compiler:

   How to build Python 313 without free threading & JIT support?

   • So, you’re going to build the vanilla flavor of Python 3.13 without free threading or JIT support. Ensure that your current working directory is where you compiled Python 3.13 before, and remove any generated build files with make clean. Then, configure the build without the experimental features and compile Python again.

   Jan 9, 2024 · In late December 2023 (Christmas Day to be precise), CPython core developer Brandt Bucher submitted a little pull-request to the Python 3.13 branch adding a JIT compiler. This change, once accepted would be one of the biggest changes to the CPython Interpreter since the Specializing Adaptive Interpreter added in Python 3.11 (which was also from Brandt along with Mark Shannon).
