   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.

   Apr 11, 2024 · Most of the prior art for copy-and-patch uses it as a fast baseline JIT, whereas CPython’s JIT is using the technique to compile optimized micro-op traces. In practice, the new JIT currently sits somewhere between the “baseline” and “optimizing” compiler tiers of other dynamic language runtimes.

   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.

   Jan 10, 2024 · The new JIT compiler is included in the plan for Python 3.13 and will be optional, requiring the CPython build to be configured with -enable-experimental-jit. The pull request with the initial code was submitted late last month by core Python developer Brandt Bucher.

   Apr 12, 2024 · PEP 744 is an informational PEP answering many common questions about CPython 3.13’s new experimental JIT compiler. My main goal for this PEP is to build community consensus around the specific criteria that the JIT should meet in order to become a permanent, non-experimental part of CPython.

   Jun 18, 2024 · One of the big-ticket items for the upcoming Python 3.13 release is an experimental just-in-time (JIT) compiler for the language; the other is, of course, the removal of the global interpreter lock (GIL), which is also an experiment.

   Which Python implementation has a JIT?

   • The only Python implementation that has a JIT is PyPy. Byt - PyPy is both a Python 2 implementation and a Python 3 implementation. There is now an experimental jit on the rust python interpreter github.com/RustPython/RustPython. The Numba project should work on Python 3.

   Will a JIT compiler speed up Python?

   • The quick summary is that we should not expect dramatic speed improvements, though along with other efforts to speed Python it is a worthwhile incremental boost. That said, moving to a JIT compiler will enable better performance in later versions.

   Does CPython have a 'just-in-time' compiler?

   • Earlier this year, an experimental “just-in-time” compiler was merged into CPython’s main development branch. While recent CPython releases have included other substantial internal changes, this addition represents a particularly significant departure from the way CPython has traditionally executed Python code.

   Can CPython be built without JIT?

   • Since it should always be possible to build CPython without the JIT, removing JIT support for a platform should not be considered a backwards-incompatible change. However, if it is reasonable to do so, the normal deprecation process should be followed as outlined in PEP 387.

   Jan 16, 2024 · Technically the Python compiler is already a JIT because it compiles from Python code into Bytecode. What people tend to mean when they say a JIT compiler, is a compiler that emits machine code. Initial benchmarks show something of a 2-9% performance improvement.
