Local AI Use (route image, TTS, STT through Lemonade)
This is a meta-skill. You run it once. After that, every later request that needs image generation, text-to-speech, or speech-to-text uses the local Lemonade Server instead of a cloud API. The agent's own LLM keeps handling text; only the expensive multimodal calls move on-device.
The skill does three things:
- Makes sure local Lemonade is installed and running. If no modern
lemonadeCLI is found, the setup script installs the latest version of Lemonade on the user's behalf. Modern Lemonade has noservecommand — the Lemonade service (thelemonddaemon) auto-starts on install and is managed by the OS — so the setup script waits for the service and, if it stays down, prints the exact OS-specific command to start it (e.g.sudo systemctl start lemondon Linux). - Verifies that local Lemonade is reachable.
- Drops a
Local AI Useblock into the workspaceAGENTS.mdso the agent reads the routing rule on every later turn, in Cursor, Claude Code, Codex, Gemini CLI, and any other agent that respectsAGENTS.md.
Requires modern Lemonade (v10.1.0 or newer). Modern Lemonade unified everything under one
lemonadeCLI (lemonade status,lemonade pull, ...) driving an always-onlemondservice.lemonadeis the only valid CLI, and this skill installs Lemonade only from the official install paths listed in Step 1a. If an olderlemonadeis already on thePATHit will shadow the modern CLI; uninstall it first (see the removal commands in Step 1a) before running this skill.
Models are not downloaded during setup. Each default model is pulled lazily, on first use, by the routing rule (e.g. the first image request pulls the image model). This keeps setup fast and avoids gigabytes of downloads the user may never need.
When to use this skill
Use this skill when all of the following are true:
- The user wants local Lemonade. If it is not yet installed, the setup script installs the latest version for them automatically.
- The user accepts the default Lemonade endpoint
http://localhost:13305. - The user wants the change to be persistent across future turns and agent restarts (the rule is written to disk).
If the user is instead embedding Lemonade as a private subprocess inside
an app installer, do not use this skill; use local-ai-app-integration
instead.
Prerequisites
- OS: Windows 11 x64, Ubuntu/Debian x64, or macOS (beta).
- Lemonade: the setup script installs the latest version if missing, using
wingeton Windows, theppa:lemonade-team/stablePPA on Ubuntu/Debian, and the Homebrew cask on macOS (see Step 1a for the fallbacks). Thelemondservice auto-starts after install; the script waits for it rather than launching it. On Linux the install needssudo. Pass--no-installif the user wants to install it themselves instead. - Disk: ~8 GB free for the three default models (SD-Turbo + Whisper-Tiny
- kokoro-v1), plus ~0.1 GB for the installer itself. The first image request
also triggers a ~5 GB pull for
SD-Turboif it is not already cached; on metered or slow links, consider pulling models eagerly after setup (seelemonade pullinreference.md).
- kokoro-v1), plus ~0.1 GB for the installer itself. The first image request
also triggers a ~5 GB pull for
- Network: required for the install download and the first
lemonade pullof each model. After that, every modality runs offline. - Version: requires v10.1.0 or newer (the unified
lemonadeCLI this skill targets). Model IDs andsystem-infofields can change between releases; confirm againstlemonade statusandGET /api/v1/modelson the version actually installed rather than assuming this document is current.
The opinionated path
Run this checklist top to bottom. Track progress against it; do not move on until each step verifies.
[ ] 1. Ensure Lemonade Server is installed and running (auto-install if missing)
[ ] 2. Install the routing rule into the workspace AGENTS.md
On a managed or shared machine where the agent must not run
sudo apt-get install, pass --no-install to the setup script and confirm
Lemonade is already installed before continuing.
The single command that does both steps in one shot is:
python scripts/setup_local_ai.py
Always run this script first — even if Lemonade is already installed and the
server is already running, and even before generating a single image. Writing
the routing rule into AGENTS.md is what makes this skill complete; skipping it
because "Lemonade is already up" leaves the workspace unconfigured for future
turns. The script is safe to run in that case: it detects the running service,
skips the install, and just writes the rule.
It auto-installs the latest version of Lemonade if no modern lemonade CLI
is found, waits for the auto-started lemond service, then writes the rule.
The script is idempotent: re-running it on a fully configured workspace is a
no-op apart from a healthcheck. Read the sections below for what to do when
each step fails.
Step 1: ensure Lemonade Server is installed and running
scripts/setup_local_ai.py handles this end to end, but here is what it does
so you can do it by hand or debug it. Pass --no-install when Lemonade is
already managed elsewhere and the agent must not attempt a package install.
1a. Is a modern lemonade CLI installed? Run lemonade status. The check
is by capability, not by name: modern Lemonade prints Server is running...
or Server is not running. If instead you get an "invalid choice" / usage
error, the lemonade on PATH is an old build that predates the unified CLI
(v10.1.0) — do not use it. Remove it, then re-run this skill:
| OS | Uninstall the old build with |
|---|---|
| Windows | winget uninstall -e --id AMD.LemonadeServer, or Settings > Apps > Installed apps > Lemonade Server > Uninstall |
| Ubuntu/Debian | sudo apt remove lemonade-server |
| macOS | brew uninstall --cask lemonade-server, or delete the installed Lemonade.app and its .pkg receipt |
Never try to drive or auto-remove it for the user.
If no lemonade is found at all, install the latest version on the user's
behalf. Use the package manager first; the download is the fallback when the
package manager is absent. Full matrix, including Arch, Fedora, Debian, Snap,
and Docker, is in the install docs.
| OS | Install | Fallback |
|---|---|---|
| Windows | winget install -e --id AMD.LemonadeServer |
Download lemonade.msi and run msiexec /i lemonade.msi /qn (silent, per-user, no elevation). |
| Ubuntu | sudo add-apt-repository -y ppa:lemonade-team/stable && sudo apt-get update && sudo apt-get install -y lemonade-server |
sudo snap install lemonade-server |
| macOS | brew install --cask lemonade-server |
Download Lemonade-<ver>-Darwin.pkg from the latest release and run sudo installer -pkg Lemonade-<ver>-Darwin.pkg -target /. |
The Ubuntu apt package is named lemonade-server, but the CLI it installs is
lemonade. The browser UI is served at http://localhost:13305 with no extra
package; add sudo apt install lemonade-desktop only if the user wants the
desktop frontend.
After a Windows install the CLI lands in %LOCALAPPDATA%\lemonade_server and
is added to the user PATH (new shells only); the setup script probes that
directory so it works in the same run.
1b. Is the service running? Check lemonade status --json. The lemond
service auto-starts on install — there is no lemonade serve in modern
Lemonade.
lemonade status says |
Action |
|---|---|
Server is running on port 13305 |
Continue to Step 2. |
Server is not running |
Wait a few seconds for the auto-started service (the script polls /api/v1/health). If it stays down, start it via the OS service manager: sudo systemctl start lemond (Linux system install) or systemctl --user start lemond (per-user install); launchctl load /Library/LaunchDaemons/com.lemonade.server.plist (macOS); the Lemonade tray app or Start-Service lemond (Windows). |
Only if the automatic install genuinely fails (no apt-get, no sudo,
download blocked) should you stop and point the user at
https://lemonade-server.ai/docs/guide/install/.
The rest of this skill assumes the endpoint is http://localhost:13305/api/v1
and no API key is required (the system-wide server defaults to no auth on
loopback). If the user has set LEMONADE_API_KEY, the routing rule template
in templates/local-ai-rule.md shows where to add the Authorization header.
1c. Are the backends ready per modality? Backend health is per
modality. A working chat or image request does not prove transcription will
work: auto picks a different backend per modality and can silently fall back
for one while having no alternative for another. Before declaring setup
complete, check the actual per-modality state:
lemonade backends --all
Any variant the workspace's routing depends on should read installed. If the
only installed variant for a modality is rocm, install the Vulkan variant as
well so auto has somewhere to fall back to (for example,
lemonade backends install whispercpp:vulkan).
Default modality models (pulled on first use, not during setup)
Setup does not download these. The installed rule pulls each one the first time that modality is requested. They are the smallest models Lemonade offers per modality, sized to keep token-and-cost savings real on commodity hardware:
| Modality | Model | Size | Why this default |
|---|---|---|---|
| Image generation | SD-Turbo |
~5 GB | Single-step generation, runs on CPU and AMD iGPU/dGPU |
| Text-to-speech | kokoro-v1 |
~0.3 GB | Only TTS model Lemonade currently supports; CPU-only, low latency |
| Speech-to-text | Whisper-Tiny |
~0.1 GB | Smallest Whisper; fast on CPU. Upgrade to Whisper-Large-v3-Turbo if accuracy matters more than latency. |
To write a different model ID into the rule, pass it to the setup script. For example, to make future image requests use SDXL:
python scripts/setup_local_ai.py --image-model SDXL-Turbo
That model ID is written into the installed AGENTS.md rule and pulled on its
first use. The same pattern works for --tts-model and --stt-model. For
larger / higher-quality alternatives (SDXL-Turbo, Flux-2-Klein-4B,
Whisper-Large-v3-Turbo), see the
model picker in reference.md.
Step 2: install the routing rule into AGENTS.md
The rule is a Markdown block stored in templates/local-ai-rule.md.
Append it to the workspace's AGENTS.md (create the file if missing). Both
Cursor and Claude Code load AGENTS.md automatically on every turn, so the
agent will see the rule on its next message without any further setup.
scripts/setup_local_ai.py does this for you. It bakes the selected endpoint
and model IDs into the rule, surrounded by stable markers so re-running the
script replaces the block in place rather than appending a second copy. The
markers look like:
<!-- BEGIN amd-skills:local-ai-use -->
...rule...
<!-- END amd-skills:local-ai-use -->
If you write the file by hand, keep those exact markers. The script relies on them for idempotent updates.
If the user's agent only respects a different convention, mirror the same block to:
CLAUDE.md(Claude Code, project-scoped) or~/.claude/CLAUDE.md(global).cursor/rules/local-ai-use.mdc(Cursor user/project rules)GEMINI.md(Gemini CLI)
The rule's content is identical; only the file location changes.
What changes after this skill runs
From the next turn onward, the agent reads the rule in AGENTS.md on every
message. The rule explicitly tells the agent:
- For image generation: call
POST /api/v1/images/generationson the local server. Do not call any cloud image API and do not use the built-inGenerateImagetool (that path bills tokens to the cloud provider). - For text-to-speech: call
POST /api/v1/audio/speech. Do not call cloud TTS providers (OpenAI TTS, ElevenLabs, etc.). - For speech-to-text: call
POST /api/v1/audio/transcriptions. Do not call cloud transcription providers. - Fallback: only fall back to a cloud API after one local attempt has failed and the user has been told the local call failed. Never silently; the whole point of this skill is to keep cost predictable. For speech-to-text, the disclosure must also say the transcript came from a different engine, since mixed-engine transcripts should not be compared or deduplicated.
The agent's own text reasoning continues to use whatever LLM Cursor / Claude Code / Codex is configured with. This skill does not redirect chat tokens; it only redirects the multimodal calls that would otherwise leave the machine.
Troubleshooting cheatsheet
| Symptom | Cause | Recovery |
|---|---|---|
lemonade: command not found |
CLI not installed | Re-run python scripts/setup_local_ai.py (auto-installs the latest version). If it just installed on Windows, open a new shell so the user PATH refreshes, or the script will find it under %LOCALAPPDATA%\lemonade_server. |
status gives an "invalid choice" / usage error |
An old lemonade (pre-v10.1.0) is shadowing the modern CLI |
Uninstall it (see the Step 1a table: winget uninstall -e --id AMD.LemonadeServer / sudo apt remove lemonade-server / brew uninstall --cask lemonade-server), then re-run the setup script. |
Server is not running |
lemond service stopped |
Start it via the OS service manager — sudo systemctl start lemond / systemctl --user start lemond (Linux), launchctl load /Library/LaunchDaemons/com.lemonade.server.plist (macOS), or the tray app / Start-Service lemond (Windows). There is no lemonade serve. |
POST /v1/images/generations returns 404 model not found |
Image model not downloaded | lemonade pull SD-Turbo and retry. |
lemonade pull keeps printing Progress: NN% but never finishes |
Download target is a bad path (out of space, no write permission, quota, read-only mount). The write error may surface only in the server log while the console keeps showing progress | Check the target and free space first: GET /api/v1/system-info reports models_dir and model_storage.free_bytes. If a pull stalls, read the recent lines of the server log (typically lemonade-server.log in the OS temp dir) for the real error (e.g. a download/write failure like CURL code 23, or an out-of-space message), then point the download at a writable disk with room. |
| Image generation is slow on CPU (~4–5 min) | sd-cpp on CPU backend | Install the GPU backend on supported AMD hardware: lemonade backends install sd-cpp:rocm. |
| Still slow after installing the GPU backend | The backend is installed but not actually engaged; the runtime fell back to CPU silently | An installed state in system-info and a successful rocminfo both still permit a silent CPU fallback. Check real GPU utilisation (gpu_busy_percent) during a request, and confirm the host's GPU driver stack rather than re-installing the backend. |
POST /v1/audio/transcriptions returns 400 unsupported format |
Input is not 16 kHz mono WAV | Re-encode with ffmpeg -i in.* -ar 16000 -ac 1 out.wav. |
POST /v1/audio/speech returns 404 |
TTS model not downloaded | lemonade pull kokoro-v1. |
| 401 Unauthorized on every request | User has set LEMONADE_API_KEY |
Add Authorization: Bearer $LEMONADE_API_KEY to every request and to the rule block. |
Verification checklist
Mark this skill complete only when all of the following are true:
-
lemonade status --jsonreports the server running on port 13305. - The workspace
AGENTS.mdcontains theamd-skills:local-ai-useblock. This is required even when Lemonade was already installed and running — generating an image alone does not complete the skill. - On a follow-up turn, asking the agent to "generate an image of X"
causes it to POST to
http://localhost:13305/api/v1/images/generations(pulling the model on first use) rather than calling a cloud tool. -
lemonade backends --allshowsinstalledfor every backend variant this workspace's routing depends on (see Step 1c). Do not treat a working image or chat path as proof that transcription will work.
If any box is unchecked, the user is still paying cloud cost for at least one modality, or a routed modality may fail silently on first use.
