## Summary

Meta introduces F3 Lightning, an infrastructure layer on its F3 feature framework that compiles, validates, deploys, and rolls back each ads ML feature independently. Previously all features shipped as one merged graph, so a single failing definition blocked every release. Meta says comparable extraction features now reach production about 3.6x faster than with prior F3, with no increase in infrastructure compute cost.
