OpenClaw + Ollama: Run Your AI Agent 100% Free with Local Models

API bills add up fast. At $3–$15 per million tokens, a busy agent can cost $50–$200/month. Ollama lets you run models locally for free.

Why Local Models Matter

Privacy: Your conversations never leave your machine.

Cost: Zero. After hardware, every token is free.

Speed: No network latency. Local inference can be faster than API calls.

Reliability: No rate limits, no outages, no API key issues.

Setting Up Ollama

curl -fsSL https://ollama.com/install.sh | sh
ollama pull qwen2.5:7b

Ollama exposes an OpenAI-compatible API at localhost:11434.

Best Models for OpenClaw

Daily Driver:

• Qwen 2.5 7B — Best all-rounder. Great at instructions, coding, conversation.
• Llama 3.1 8B — Strong general-purpose. Slightly better reasoning.

Lightweight:

• Qwen 2.5 3B — Runs on 4GB RAM. Surprisingly capable.
• Phi-3 Mini — Good for structured outputs.

Power Users:

• Mistral Nemo 12B — Excellent instruction following. 16GB+ RAM.
• Qwen 2.5 14B — Best local model under 16B. Needs 32GB RAM.

Performance on Raspberry Pi 5 (8GB)

• Qwen 2.5 3B: ~15 tokens/sec — fast, great for simple tasks
• Qwen 2.5 7B: ~6 tokens/sec — usable daily driver
• Llama 3.1 8B: ~5 tokens/sec — similar

When to Use Local vs Cloud

Use local for: Routine tasks, simple Q&A, privacy-sensitive content, high-volume monitoring.

Use cloud for: Complex reasoning, long-context tasks (>8K tokens), critical code generation.

Hybrid Setup

Use local models by default, route complex tasks to cloud APIs. This cuts API costs by 70–80%.

For detailed model configs and hybrid setup templates, check the Raspberry Pi Deployment Kit which includes Ollama optimization guides.
