lemonade-sdk/lemonade

Lemonade is the local AI server that gives you the same capabilities as cloud APIs, except 100% free and private. Use the latest models for chat, coding, speech, and image generation on your own NPU and GPU.

Lemonade comes in two flavors:

• Lemonade Server installs a service you can connect to hundreds of great apps using standard OpenAI, Anthropic, and Ollama APIs.
• Embeddable Lemonade is a portable binary you can package into your own application to give it multi-modal local AI that auto-optimizes for your user’s PC.

This project is built by the community for every PC, with optimizations by AMD engineers to get the most from Ryzen AI, Radeon, and Strix Halo PCs.

Platform	Build

To run and chat with Gemma:

lemonade run Gemma-4-E2B-it-GGUF

To code with Lemonade models:

lemonade launch claude

Multi-modality:

# image gen
lemonade run SDXL-Turbo

# speech gen
lemonade run kokoro-v1

# transcription
lemonade run Whisper-Large-v3-Turbo

To see available models and download them:

lemonade list

lemonade pull Gemma-4-E2B-it-GGUF

To manage model aliases for environment-independent naming and active-standby failover:

lemonade alias add production-llm Gemma-4-E2B-it-GGUF
lemonade alias list

# Instant active-standby failover to a different model target
lemonade alias add production-llm Qwen3-0.6B-GGUF
lemonade alias remove production-llm

To see the backends available on your PC:

lemonade backends

For hybrid setups, Lemonade can also route to any OpenAI-compatible cloud provider (Fireworks, OpenAI, OpenRouter, Together, …) alongside local models — see Cloud Offload. (Experimental.)

Lemonade supports a wide variety of LLMs (GGUF, FLM, and ONNX), whisper, stable diffusion, etc. models across CPU, GPU, and NPU.

Use lemonade pull or the built-in Model Manager to download models. Custom GGUF/ONNX models can be pulled from Hugging Face or ModelScope, with their source retained for future updates.

Lemonade supports multiple inference engines for LLM, speech, TTS, and image generation, and each has its own backend and hardware requirements.

† experimental backend, ‡ guest backend. See Backend Tiers and Formats.

Lemonade's roadmap is defined by a set of working groups. Visit the landing page here to learn each group's goal and roadmap.

Embeddable Lemonade is a binary version of Lemonade that you can bundle into your own app to give it a portable, auto-optimizing, multi-modal local AI stack. This lets users focus on your app, with zero Lemonade installers, branding, or telemetry.

Check out the Embeddable Lemonade guide.

You can use any OpenAI-compatible client library by configuring it to use http://localhost:13305/v1 as the base URL. A table containing official and popular OpenAI clients on different languages is shown below.

Feel free to pick and choose your preferred language.

from openai import OpenAI

# Initialize the client to use Lemonade Server
client = OpenAI(
    base_url="http://localhost:13305/api/v1",
    api_key="lemonade"  # required but unused
)

# Create a chat completion
completion = client.chat.completions.create(
    model="Gemma-4-E2B-it-GGUF",  # or any other available model
    messages=[
        {"role": "user", "content": "What is the capital of France?"}
    ]
)

# Print the response
print(completion.choices[0].message.content)
