Python 3.14 Beta 1 Released: 30% Faster Performance & New Features

 

Python 3.14 Beta 1 introduces a tail-call interpreter for 30% faster execution, T-Strings, Zstandard compression, and debugger improvements. Optimized for Clang 19+, this update boosts performance for developers, data scientists, and engineers. Download now!

🚀 Major Performance Boost: Tail-Call Interpreter (Up to 30% Faster)

Python 3.14 Beta 1 debuts an experimental tail-call interpreter, replacing the traditional monolithic C switch-case with small, optimized C functions. Early benchmarks show:

✔ Up to 30% faster execution for certain workloads

✔ 3-5% geometric mean improvement in pyperformance benchmarks

✔ Exclusive to Clang 19+ (x86-64 & AArch64), with GCC support expected later

🔧 How to Enable?

Build Python with --with-tail-call-interp and enable profile-guided optimization (PGO) for best results.
