Lemonade
Project record
Maintained by Lemonade project (sponsored and backed by AMD, with community maintainers)13
Lemonade is a local AI server that runs language, speech, and image-generation models on a PC's CPU, GPU, or NPU and exposes them through OpenAI-, Anthropic-, and Ollama-compatible APIs. It is also offered as an embeddable binary for applications, and it supports several inference engines, including llama.cpp and engines for AMD Ryzen AI NPUs.1

What it is useful for
Serving local models to existing applications through standard APIs, with backends for AMD Ryzen AI NPUs and Radeon GPUs as well as NVIDIA GPUs, Apple Silicon, and CPU-only systems.1
Run and use notes
- The README shows the lemonade CLI listing, pulling, and running models (for example a Gemma 4 E2B GGUF build) and listing the backends available on the PC.1
- The README says the program does not transfer information to other networked systems unless requested, and that model downloads contact Hugging Face or ModelScope depending on the model source.1
Organization context
Provenance and derivatives
Lemonade uses llama.cpp, whisper.cpp, stable-diffusion.cpp, ONNX Runtime GenAI, and other projects as inference engines, per its README.1
- Derived from: llama.cpp — Text-generation engine (llamacpp backends).
- Derived from: ONNX Runtime GenAI (external site: github.com) — Listed among the tools Lemonade builds on.
U.S. eligibility
Eligible · basis: U.S.-governed project
Lemonade's README says the project is sponsored by AMD, built with optimizations by AMD engineers, and gives an amd.com address as its contact. AMD's developer article calls Lemonade an open-source project backed by AMD and points readers to "our GitHub" and "our YouTube channel", presenting the project as AMD's own. AMD, a U.S. company in this catalog, is therefore treated as the documented maintaining entity. The README also describes many community maintainers, and the LICENSE names "Lemonade Community" as copyright holder; both are recorded. Eligibility does not rest on any contributor's affiliation or nationality.1632
