Free-threaded Python (3.13t/3.14t) is an experimental build of CPython that removes the global interpreter lock (GIL) and allows multiple threads to truly execute Python bytecode in parallel; many C extensions have not yet been adapted to it; the installer installs 3.13t and 3.14t side by side, giving users the option to experiment with GIL-free concurrency without affecting the default 3.12 environment.
