A high-performance, zero-overhead, extensible Python compiler with built-in NumPy support - exaloop/codon

Codon reads Python code and organizes it into a form the compiler can analyze.

April 25, 2023 - The article's author, Rachel Gordon, stressed that Codon can compile Python scripts into native code that is as fast, and sometimes faster, than hand-crafted code in C/C++. But quotes from Ariya Shajii, one of Codon’s two developers, mentioned that there were also limitations, in that some of the dynamic features of Python would not work, and that not all of Python 3 was available.

Exaloop’s Codon framework compiles Python to native machine code for 10-100x performance gains, multithreading, GPU acceleration & more.

March 14, 2023 - Codon is a new tool that compiles Python code to run it more efficiently and effectively while allowing for customization and adaptation to various domains.

Python programs and leverages a novel intermediate repre- sentation to easily incorporate domain-specific optimizations · and analyses. We showcase and evaluate several compiler · extensions and DSLs for Codon targeting various domains,

May 11, 2023 - Created as a way to speed processing of genomic data, Cordon can compile some Python programs at a fraction of the speed of the Python compiler itself.

March 10, 2025 - In their blog post, the authors provide charts showing the improvement of Codon over regular Python when running the NPBench NumPy benchmarks. The geometric mean of speedups is modest, 2.4x, but the maximum is crazy, at 900x.

August 9, 2026 - Researchers from the Massachusetts Institute of Technology and the University of Victoria have released a compiler dubbed Codon that, they say, can make a Python program run at the speed of of a C program — or even faster, with domain-specific ...

March 12, 2023 - As described in a paper [PDF] provided to The Register in advance of its planned March 16 release, "Codon: A Compiler for High-Performance Pythonic Applications and DSLs," the toolchain "enables the development of DSLs that share Python’s syntax and semantics together with added domain-specific features and IR optimizations."

December 21, 2025 - Learn how Codon achieves 100x Python speedups through AOT compilation. Native multithreading, GPU kernels, zero overhead.

Codon is a high-performance Python compiler that compiles Python code to native machine code without any runtime overhead. Typical speedups over Python are on the order of 100x or more, on a single thread.

Codon strives to be as close to Python (specifically, CPython) as possible, outside of a few differences that stem from performance considerations or incompatibilities with Codon's static compilation paradigm.

April 3, 2026 - This is not a bug. This is what C/C++ have been doing since before Python learned to walk. Codon assumes you know what a 64-bit integer is.

It translates the Python into a C++ program that then uses "libpython" to execute in the same way as CPython does, in a very compatible way. Codon is great to run inside a Linux Container (LXD), as it is fairly self contained, and you can then move the compiled binary to another compatible ...

Codon is a high-performance Python compiler that compiles Python code to native machine code without any runtime overhead. Typical speedups over Python are on the order of 100x or more, on a single thread.

The codon project was created to increase code sharing, code consistency, coding standards, and encourage collaboration. Package documentation is available on the GitHub pages. codonPython aims to reduce the barrier for entry for analysis and provide software development experience for those at a higher level of technical ability.

March 14, 2023 - However, a new python compiler that I find fascinating recently popped up. Codon by Exaloop is a new python compiler that can compile directly to machine code. It uses the LLVM framework to compile to LLVM bytecode and then to specific machine code.
