JoyAI-Echo Overlay
Overlay metadata repo for using jdopensource/JoyAI-Echo with native SGLang Diffusion JoyEcho support.
This repo contains only overlay metadata and materialization logic. Source weights remain in jdopensource/JoyAI-Echo, while donor revisions are pinned here so re-materializing the model does not drift when upstream donor repos change.
Layout
model_index.json— JoyEchoPipeline component index_overlay/overlay_manifest.json— source model pin + materializer version_overlay/materialize.py— monolithic safetensors → diffusers layout
Usage (SGLang)
sglang generate --model-path jdopensource/JoyAI-Echo ...
SGLang resolves this overlay via BUILTIN_MODEL_OVERLAY_REGISTRY, materializes into ~/.cache/sgl_diffusion/materialized_models/, then loads via standard ComposedPipelineBase.load_modules().
