Provenance by Default: AI Media Pipelines in Python
A model can now generate a video that looks indistinguishable from one your camera recorded. The same is true for an image, a voice, or a song. As Python developers, we are building those pipelines — and we are also the ones who will be asked, very soon, to prove what came out of them. This talk is about building generative media pipelines in Python in a way that answers that question by default. We'll walk through Genblaze, an open-source SDK (github.com/backblaze-labs/genblaze, MIT licensed) that I work on at Backblaze, and use it as a vehicle to talk about the design problems any team faces when wiring AI generation into a real product. We will cover, with live code: the Pipeline pattern with a fluent Pipeline → Step → Run → Manifest API built on Pydantic v2; one API across eleven providers; provenance that survives the file with SHA-256-verified manifests embedded into PNG, JPEG, MP4, MP3, and WAV; privacy and policy controls; storage and replay; and agent loops with lineage. By the end, attendees will have a clear reference for how to architect generative-AI features in Python so that what did this system actually produce, and can I prove it? is a one-line answer instead of a ticket.
