 Free-threaded CPython now supports :pep:`659` which is known

+as the specializing adaptive interpreter. The execution mechanism is almost same
 as the default build, but at free-threaded CPython build, each thread maintains
 a thread-local copy of specialized bytecode.
 
-With this change, the free-threaded CPython build achieve better performance

 This work was done by many contributors, Matt Page, Neil Schemenauer,
 Sam Gross, Thomas Wouters, Donghee Na, Kirill Podoprigora and Ken Jin.
-Meta also provided significant engineering resources for performance benchmark and
