More Resources

Apart from this website, there's a wide list of resources on the free-threaded build and free-threading topics in general, including documentation, blog posts, conference talks, and others. We'll try to keep an up-to-date list here:

• Sam Gross's EuroPython talk
• PEP 703 design document
• C API Extension Support for Free Threading HOWTO on docs.python.org
• ft_utils documentation
• PEP 703 initial discussion thread, as well as the follow-up discussion thread
• PEP 703 acceptance announcement
• Quansight Labs blog post about work on free-threading
• Simon Willison's post about trying out free-threaded Python on macOS
• Codspeed's blog post about free-threading performance

There's also a lot of useful resources on CPython internals, that are not specific to the free-threaded build:

• CPython internal docs
• Dated tutorial on writing C extension modules
• Python behind the scenes series
• Łukasz Langa's PyCon Thailand talk on the Python 3.13 release
• Anthony Shaw's PyCon US talk on free-threading and other parallelism concepts
