     • The Just-in-Time compiler An experimental JIT (Just-in-time) compiler is now part of the main branch in Python. However, in Python 3.13, it is turned off by default. It is not part of the default build configuration and will likely stay that way in the foreseeable future.

   2 days ago · When CPython is configured and built using the --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 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.

   May 20, 2024 · Python introduces an experimental just-in-time (JIT) compiler which, when enabled, can speed up certain Python programs. The JIT compiler works by translating specialized Tier 1 bytecode to a new internal Tier 2 intermediate representation (IR), which is optimized for translation to machine code.

   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.
