Lemonade now fronts 15 inference engines behind one base URL with semantic and policy routing.

The end-of-summer update covers CUDA, ARM64, Metal and Vulkan backends for all core engines, experimental engines for music and 3D asset generation, and a router doing semantic and policy routing. It installs as a single OS service managing models and engines behind one base URL, and ships as an embeddable SDK (r/LocalLLaMA). Maintainers confirmed DGX Spark support in-thread, and noted you can point the config at your own llama-server binary to run llama.cpp PRs early while keeping Lemonade's routing. That last trick is how you test an unmerged PR without abandoning your stack.
