The new interpreter will run Python programs as much as 5% faster, with no changes to existing code required. A beta of Python 3.14 is due in May.

Using a fork of the Nuitka Python compiler, py2wasm converts Python programs to Wasm, allowing them to run without interpreter overhead.

Writing a compiler seems like a much harder problem than an interpreter. If that is so, why was the first compiler written six years before the first interpreter?

Circuit Python is based on the Open Source MicroPython, a Python 3 interpreter that implements a subset of the Python language on microcontrollers and other constrained environments.
