AB  - This contribution reviews CT25, a new generation of CTEQ--TEA parton distribution functions (PDFs) for precision QCD. With its first member sets released in 2025, the CT25 family addresses common uses of parton distributions in diverse contexts. We describe the CTEQ--TEA Parton Cloud, an online database of exploratory global fits to precision QCD measurements, from which we select PDF solutions for general- and special-purpose calculations. These solutions are published as complementary error PDF ensembles---the baseline CT25, CT25m, CT25pd, and ensembles with conservative priors---optimized for distinct uses. They implement new approaches to quantifying uncertainties and different treatments of theoretical, parametrization, and nuclear-target uncertainties. In particular, they provide complementary frameworks for exploring PDF uncertainties at large partonic momentum fractions relevant to HL-LHC and EIC studies. Further details will appear in the forthcoming CT25 publication.
