Anthropic invests $1.5 million in the Python Software Foundation and open source security. This is outstanding news, especially given our decision to withdraw from that NSF grant application back in October.

We are thrilled to announce that Anthropic has entered into a two-year partnership with the Python Software Foundation (PSF) to contribute a landmark total of $1.5 million to support the foundation’s work, with an emphasis on Python ecosystem security. This investment will enable the PSF to make crucial security advances to CPython and the Python Package Index (PyPI) benefiting all users, and it will also sustain the foundation’s core work supporting the Python language, ecosystem, and global community.

Note that while security is a focus these funds will also support other aspects of the PSF's work:

Anthropic’s support will also go towards the PSF’s core work, including the Developer in Residence program driving contributions to CPython, community support through grants and other programs, running core infrastructure such as PyPI, and more.
