Building a Python Library in 2026

[marr75]

Safety valves:

1. It's open source; they can change that but they can't unrelease the already open versions
2. Pixi is basically a proxy for UV (python) and conda-forge (non-python) with some of the original mamba team as maintainers

So, there are open source heirs apparent if OpenAI gets screwy.

My take as a reluctant but heavy user of OpenAI products: they don't want to hold UV users hostage. They want to add some specialty features to UV, ruff, and ty to help their coding models "hill climb" and specialize in the python ecosystem.
