+
+[RKLLM](https://github.com/airockchip/rknn-llm) runs converted language
+models on supported Rockchip NPUs. Its server already exposes an
+OpenAI-compatible chat-completions API, so LocalAI can put its authentication,
+routing, usage tracking, and web UI in front of the board with the
+`cloud-proxy` backend.
+
+This integration does not install or convert RKLLM models. Model conversion is
+a separate host-side step using RKLLM-Toolkit, and the resulting `.rkllm` file
+must match the target SoC.
+
+## Requirements
+
+- A Linux Rockchip board supported by the installed RKLLM runtime. Upstream
+  RKLLM 1.3.0 accepts `rk3588`, `rk3576`, `rv1126b`, and `rk3562` in its server
+  demo.
+- A model converted to `.rkllm` for that target.
+- The upstream RKLLM Flask server running on the board and reachable from
+  LocalAI.
+
+RK3566 boards, including Quartz64 models with that SoC, are not in the current
+upstream RKLLM server target list. LocalAI cannot add support for a SoC that the
+RKLLM runtime does not support.
+
+## Start the RKLLM server
+
+Follow the upstream
+[`rkllm_server_demo`](https://github.com/airockchip/rknn-llm/tree/main/examples/rkllm_server_demo)
+instructions to deploy the runtime library, server, and converted model to the
+board. For example, from an RKLLM checkout on the host:
+
+```bash
+cd examples/rkllm_server_demo
+./build_rkllm_server_flask.sh \
+  --workshop /userdata/rkllm-server \
+  --model_path /userdata/models/qwen3.rkllm \
+  --platform rk3588 \
+  --adb_device YOUR_DEVICE_SERIAL
+```
+
+The helper starts the server on port `8080`. Confirm it is reachable before
+configuring LocalAI:
+
+```bash
+curl http://ROCKCHIP_BOARD_IP:8080/v1/models
+```
+
+## Configure LocalAI
+
+Create `models/rkllm.yaml`:
+
+```yaml
+name: rockchip-rkllm
+backend: cloud-proxy
+
+proxy:
+  mode: passthrough
+  provider: openai
+  upstream_url: http://ROCKCHIP_BOARD_IP:8080/v1/chat/completions
+  upstream_model: rkllm
+  request_timeout_seconds: 600
+
+# The upstream is on the local network, so cloud-egress PII filtering is not
+# enabled by default in this example. Enable it if your deployment needs it.
+pii:
+  enabled: false
+```
+
+No API key setting is required by the upstream demo server. If you expose the
+board beyond a trusted network, put an authenticated reverse proxy in front of
+it and configure the corresponding key through `api_key_env` or `api_key_file`.
+
+Start LocalAI, then use the local model name with any OpenAI-compatible client:
+
+```bash
+curl http://localhost:8080/v1/chat/completions \
+  -H 'Content-Type: application/json' \
+  -d '{
+    "model": "rockchip-rkllm",
+    "messages": [{"role": "user", "content": "Hello"}],
+    "stream": true
+  }'
+```
+
+LocalAI forwards the request and the streaming response without translating
+the wire format. Sampling fields supported by the upstream server, including
+`temperature`, `top_p`, `top_k`, `max_tokens`, `repeat_penalty`, and
+`enable_thinking`, pass through unchanged.
+
+## Limitations
+
+- The upstream demo serves chat completions and model listing only. Embeddings,
+  image generation, audio APIs, and legacy text completions are not available.
+- Model conversion and runtime installation remain upstream RKLLM operations.
+- Upstream serializes inference for a loaded model and returns HTTP 503 while
+  it is busy. Scale with multiple boards and LocalAI routing if concurrent
+  inference is required.
+- The upstream demo returns model-generated tool calls as markup in
+  `message.content`; passthrough mode does not convert that markup into OpenAI
+  `message.tool_calls`. Clients that use tools must parse the model-specific
+  format or put an adapter in front of the RKLLM server.
+
+See [Cloud passthrough proxy]({{% relref "operations/cloud-proxy" %}}) for the
+full proxy configuration, authentication, routing, and PII options.
