About Lemonade

Lemonade is an open source local AI server that runs language, speech, transcription, and image-generation models on a user's own CPU, GPU, and NPU hardware. It offers Lemonade Server for connecting apps through OpenAI, Anthropic, and Ollama-compatible APIs, and an embeddable portable binary for packaging local AI into other applications.

It includes a Model Manager and CLI commands to list, download, run, and alias models, including GGUF, FLM, ONNX, Whisper, and Stable Diffusion types, with custom models from Hugging Face or ModelScope. Hardware support varies by inference engine, backend, device, and operating system, and routing to OpenAI-compatible cloud providers is listed as experimental.
