F3 serves requests that can require more than 20,000 features per request; Meta first presented F3 at AI @ Scale 2020 and published the F3 Lightning update on its Engineering at Meta blog on November 3, 2026. The post matters to teams running large-scale feature pipelines because it describes how Meta moves ads ML features into production.", "body_md": "Facebook Feature Framework (F3) is Meta’s framework for authoring, compiling, and serving the machine learning features underlying ads ranking models, where a single request can require more than 20,000 features.
