InfraLens - DiffSynth Annotated Labs

Overview

DiffSynth Annotated Code Reading Labs

Read the related handbook section first, then use the lab page and starter file to connect the concept to concrete variables, shapes, APIs, and interview-ready explanations.

Goals

How to use these labs

Read the related handbook section first, then use the lab page and starter file to connect the concept to concrete variables, shapes, APIs, and interview-ready explanations.

Read this after the DiffSynth Pipeline Reading handbook and, when diffusion concepts are unfamiliar, the Diffuser track. Then open the lab page and starter file. For each line, ask what config, tensor, model component, or pipeline transition it represents.

Version-sensitive note: DiffSynth API fields should be checked against current project docs before release.
