This issue to track work for enablement of Python 3.14/3.14t . Similar to: #130249

Current Status Source build

Current Status Nightlies:

Projected for Release 2.9.0

Python 3.14 is coming out in the near future - RC1 is planned for July 22 (first point at which the ABI is stable and packages can start releasing wheels for 3.14), and the final release is planned for 4th Oct 2025 (see PEP 719).

Outstanding work:

• Add Python NoGil Support in CI Add Python NoGil support in CI #156854

Here is a hopefully useful breakdown in steps to support Python 3.14:

• PyTorch builds from source on 3.14 Fix compilation and "import torch" issues for cpython 3.14 #158184
• Try wheel Linux builds with PyThon 3.14 Linux py 3.14 wheel builds #157559
• Nightly cp314 wheels available for all platforms (waiting until final cpython rc)
• torch.compile support for 3.14 (complete @williamwen42 )
• PyTorch builds from source with free-threaded CPython
• cp314t (free-threaded) nightly wheels available (blocked on ft build and dependencies)

Python 3.14 CD:

• Nightly cp314 Linux wheels available.
• Nightly windows wheels
• Nightly macos
• Nightly aarch64 wheels

Python 3.14 CI & torch.compile:
