Python's experimental just-in-time (JIT) compiler, introduced to CPython in 2024 for the 3.13 release, is set to be removed. The Python steering council paused work on the JIT in CPython's main branch in June, pending an accepted Python Enhancement Proposal (PEP) that would address concerns regarding maintenance, compatibility, and establish clear success metrics and a completion timeline.
