* feat(cli): support systemd socket activation Serve the API from a single stream listener inherited through the systemd activation protocol while retaining the existing address bind path when no listener is provided. Validate activation metadata, preserve the public-bind safety check, and document an on-demand systemd setup. Assisted-by: Codex:gpt-5 * fix(cli): satisfy listener cleanup lint Make the best-effort close explicit so errcheck accepts the deferred systemd listener cleanup.

## Manual Installation
|
|
|
|
### Download Binary
|
|
|
|
You can manually download the appropriate binary for your system from the [releases page](https://github.com/mudler/LocalAI/releases):
|
|
|
|
1. Go to [GitHub Releases](https://github.com/mudler/LocalAI/releases)
|
|
2. Download the binary for your architecture (amd64, arm64, etc.)
|
|
3. Make it executable:
|
|
|
|
```bash
|
|
chmod +x local-ai-*
|
|
```
|
|
|
|
4. Run LocalAI:
|
|
|
|
```bash
|
|
./local-ai-*
|
|
```
|
|
|
|
### Run your first model
|
|
|
|
Starting the binary on its own gives you an empty server. To get a working chat right away, run LocalAI with a model name and it will download and serve it from the gallery:
|
|
|
|
```bash
|
|
./local-ai-* run qwen3-4b
|
|
```
|
|
|
|
Once it is ready, open the WebUI at `http://localhost:8080` or send a request to the API:
|
|
|
|
```bash
|
|
curl http://localhost:8080/v1/chat/completions -H "Content-Type: application/json" -d '{
|
|
"model": "qwen3-4b",
|
|
"messages": [{"role": "user", "content": "Hello!"}]
|
|
}'
|
|
```
|
|
|
|
### System Requirements
|
|
|
|
Hardware requirements vary based on:
|
|
- Model size
|
|
- Quantization method
|
|
- Backend used
|
|
|
|
For performance benchmarks with different backends like `llama.cpp`, visit [this link](https://github.com/ggerganov/llama.cpp#memorydisk-requirements).
|
|
|
|
## Configuration
|
|
|
|
After installation, you can:
|
|
|
|
- Access the WebUI at `http://localhost:8080`
|
|
- Configure models in the models directory
|
|
- Customize settings via environment variables or config files
|
|
|
|
## Start LocalAI on demand with systemd
|
|
|
|
LocalAI accepts a single TCP listener passed through the systemd socket
|
|
activation protocol. This lets systemd listen on the public port and start
|
|
LocalAI only when the first client connects.
|
|
|
|
Create `/etc/systemd/system/local-ai.socket`:
|
|
|
|
```ini
|
|
[Unit]
|
|
Description=LocalAI API socket
|
|
|
|
[Socket]
|
|
ListenStream=8080
|
|
NoDelay=true
|
|
|
|
[Install]
|
|
WantedBy=sockets.target
|
|
```
|
|
|
|
Create the matching `/etc/systemd/system/local-ai.service`:
|
|
|
|
```ini
|
|
[Unit]
|
|
Description=LocalAI
|
|
|
|
[Service]
|
|
Type=simple
|
|
User=localai
|
|
Group=localai
|
|
ExecStart=/usr/local/bin/local-ai run
|
|
WorkingDirectory=/var/lib/local-ai
|
|
```
|
|
|
|
Adjust the user, binary path, working directory, and model configuration for
|
|
your installation. Then enable the socket, not the service:
|
|
|
|
```bash
|
|
sudo systemctl daemon-reload
|
|
sudo systemctl enable --now local-ai.socket
|
|
```
|
|
|
|
The first connection to port 8080 starts `local-ai.service`; systemd holds that
|
|
connection until LocalAI is ready to accept it. `LOCALAI_ADDRESS` and
|
|
`--address` are ignored while an inherited listener is present. LocalAI
|
|
rejects activation with multiple stream listeners so it cannot silently choose
|
|
the wrong endpoint.
|
|
|
|
For a Podman-managed container, configure Podman to preserve and pass the
|
|
systemd socket file descriptor into the container. The LocalAI process inside
|
|
the container consumes the same activation protocol.
