Frequently Asked Questions
What's the best model for OpenClaw in 2026?
Claude Sonnet 4.5 is our top recommendation — it excels at coding, writing, and complex instructions at a reasonable price ($3/$15 per million tokens). For budget users, DeepSeek V3 offers frontier-class performance at 10x lower cost.
Can I switch AI models without losing my conversations?
Yes! OpenClaw stores your conversation history and memories locally, so you can switch models anytime. Your context persists regardless of which AI you use.
How much does it cost to run OpenClaw with Claude?
For typical personal use (20-50 messages/day), expect $3-8/month with Claude Sonnet 4.5. Use Claude Haiku 4.5 ($1-3/month) for lighter use, or DeepSeek V3 ($0.15-0.30/month) for maximum savings.
Can I use multiple models?
Yes! OpenClaw supports model routing — use a cheap model (Gemini Flash, GPT-4o-mini) for simple tasks and a capable model (Claude Sonnet) for complex ones. This can cut costs by 50-80%.
Is DeepSeek safe to use?
DeepSeek is a Chinese company, so consider your data sensitivity. For most personal assistant tasks, it's fine. For sensitive business or personal data, stick with US/EU providers (Claude, GPT-4o) or run models locally.
Can I run OpenClaw completely free?
Yes! Use Gemini 2.0 Flash's free tier (60 requests/minute) or run Llama locally via Ollama. The free tier is generous enough for most personal use.
Which model is best for coding?
Claude Sonnet 4.5 leads coding benchmarks (SWE-bench). DeepSeek V3 is nearly as good at 1/10th the cost. Both are excellent for writing, debugging, and understanding code.
The Bottom Line
For most users, Claude Sonnet 4.5 is the sweet spot — excellent at coding, writing, and complex tasks at $3-8/month. DeepSeek V3 is the value champion if you want frontier performance at 1/10th the cost. Gemini 2.0 Flash is perfect for free usage.
