How to Connect Your GPU-Hosted LLM to OpenClaw.ai
Running your own LLM on a GPU is empowering. Connecting it safely to real tools is the hard part.
This guide walks through how to connect a GPU-hosted LLM (local or cloud) to OpenClaw.ai, so your model can execute actions, call tools, and stay under your control.
No magic. No SaaS lock-in. Just a clean control plane.
Why Connect Your Own LLM to OpenClaw?
If you're already hosting an LLM on a GPU (AWS, GCP, Lambda Labs, on-prem, or DGX), you probably want:
- Full control over models, weights, and prompts
- Predictable latency and cost
- The ability to execute tools (CLI, APIs, workflows)
- A secure boundary between reasoning and execution
That's exactly what OpenClaw is designed for.
OpenClaw doesn't replace your model. It wraps it with structure, permissions, and execution safety.
Architecture Overview
At a high level, you're splitting responsibilities:
- Your GPU → reasoning, planning, text generation
- OpenClaw → tool execution, safety, permissions, observability
Flow:
- User or system prompt hits your LLM
- LLM decides what to do
- OpenClaw decides whether it's allowed
- Tool executes in a sandbox
- Result flows back to the LLM
Step 1: Run Your LLM on a GPU
You can host your model however you want, as long as it exposes an HTTP API.
Common setups:
- vLLM (recommended for throughput)
- Ollama (simple + local)
- TGI / Text Generation Inference
- Custom FastAPI / Flask wrapper
Example (FastAPI):
from fastapi import FastAPI
from pydantic import BaseModel
app = FastAPI()
class Prompt(BaseModel):
input: str
@app.post("/generate")
def generate(prompt: Prompt):
output = llm.generate(prompt.input)
return {"text": output}
Your GPU does one job only: generate text.
Step 2: Install OpenClaw
OpenClaw runs as a separate service (local or remote).
curl -fsSL https://openclaw.ai/install.sh | bash
This gives you:
- A secure execution runtime
- A policy engine
- A tool registry
- Audit logs
Think of it as a control plane for AI actions.
Step 3: Register Your LLM as a Reasoning Engine
Tell OpenClaw where your model lives:
llm:
name: gpu-llm
type: http
endpoint: http://gpu-llm:8000/generate
timeout_ms: 30000
OpenClaw does not need your weights. It just needs a clean interface.
Step 4: Define Tools Your LLM Can Use
This is where OpenClaw shines.
Example: allow safe shell commands.
tools:
- name: list_files
type: shell
command: ls
sandbox: true
permissions:
- read_only
Or API calls:
tools:
- name: create_ticket
type: http
method: POST
url: https://api.internal.com/tickets
Your LLM can request tools. OpenClaw decides if they're allowed.
Step 5: Let the LLM Call Tools (Safely)
Your prompt format might look like:
You are an agent.
If an action is required, respond in JSON:
{
"tool": "list_files",
"reason": "Check directory contents"
}
OpenClaw:
- Parses the intent
- Validates permissions
- Executes the tool
- Returns structured output
Your LLM never touches the system directly.
Step 6: Observe, Audit, and Iterate
Every action is logged:
- Tool name
- Inputs / outputs
- Execution time
- Success / failure
This matters when:
- You deploy to teams
- You expose agents to users
- You care about security reviews
Common Deployment Patterns
Local GPU + OpenClaw
- Ideal for research and experimentation
Cloud GPU + OpenClaw
- Production agents
- Team access
- Strong isolation
Multiple LLMs, One OpenClaw
- Fast model for routing
- Big model for reasoning
- Same execution layer
What This Buys You
By separating reasoning from execution, you get:
- 🔐 Strong security boundaries
- 🧠 Model flexibility (swap anytime)
- 🛠 Tool reuse across agents
- 📊 Real observability
- 🚫 No prompt-based "hope and pray" safety
This is the difference between chatbots and real agents.
Final Thoughts
If you're serious enough to host your own GPU, you're serious enough to control execution.
OpenClaw gives you:
- The freedom of self-hosted LLMs
- The discipline of production systems
Your model thinks. OpenClaw acts.
If you want, next we can:
- Add streaming
- Add multi-agent routing
- Lock this down for enterprise
- Or turn this into a "WP Engine for AI agents" style deployment
Just say the word.
Deploy OpenClaw with Clawctl — control plane for your GPU-hosted LLM.
