Comes with a JIT compiler
- JIT compiler CPython 3.13 comes with a JIT compiler (disabled by default for now). It doesn’t make things much faster yet, but the infrastructure is there. Just like the Specializing Adaptive Interpreter, it will slowly gain support for more Python and in theory make a future version faster. It works using a copy-and-patch approach.

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.
