lemonade-sdk/lemonade v11.0.0 on GitHub

Headline

A new 3D-generation modality ports the Trellis.2 image-to-3D pipeline, exposing a POST /v1/3d/generations endpoint and a GUI 3D panel with an in-app model viewer.
Text-to-speech arrives with the OpenMOSS backend, including voice-cloning and voice-design models and a dedicated TTS panel in the GUI.
Naming a collection.router model on /chat/completions, /completions, or /responses now runs its routing engine and reports the selected route via an x_lemonade_route body field and x-lemonade-route header.
ModelScope is now supported as a second remote model registry alongside Hugging Face, with source selection across the CLI, API, and desktop app.
The FastFlowLM NPU backend now auto-installs on Linux instead of requiring a manual system-package install, with a new prefer_system config flag.

Breaking Changes

The Docker runtime image now runs lemond as unprivileged UID 10001 and stores caches under /opt/lemonade/.cache instead of /root/.cache; chown or recreate existing root-owned named volumes.
Re-registering a Hugging Face user model under a name already used by a different checkpoint now returns an error instead of silently overwriting the existing user.* model; choose a different name.
