How to Change Model In Openclaw
Learn how to choose the right AI model for better speed, lower cost, stronger output quality, and more reliable OpenClaw workflows before running real automation.
What Is Model Switching in OpenClaw?
Changing the model in OpenClaw means changing the AI system your agent uses to think, reply, plan tasks, and complete workflows.
It is not just a small chat setting. The model can affect how OpenClaw understands instructions, uses tools, handles automation, writes responses, and follows your workflow rules.
For example, a stronger model may be better for coding, research, and planning. A faster and cheaper model may be enough for reminders, basic replies, or simple daily tasks.
The goal is not to use the most powerful model everywhere. That is how people turn “automation” into “monthly billing regret.” The real goal is to choose the right model for the right job.
Why Model Selection Matters for AI Agents
The model decides how well your OpenClaw agent understands tasks, follows instructions, and gives useful answers. A stronger model can handle complex workflows better, while a weaker model may miss details or give shallow responses.
Some models respond faster than others. For quick tasks like reminders, short replies, and simple updates, a lightweight model can feel smoother than using a heavy model for everything.
Using an expensive model for every small task can increase your cost quickly. Model selection helps you use powerful models only where they matter and cheaper models for routine automation.
AI agents often use tools, follow steps, and complete tasks across apps. The right model can understand instructions better, avoid mistakes, and keep workflows more consistent.
Not every task needs the same AI model. Writing, coding, research, file organization, and daily reminders all need different levels of reasoning, speed, and accuracy.
A poor model choice can create vague answers, missed steps, or broken workflow results. Choosing the right model helps OpenClaw produce cleaner, more useful output.
OpenClaw can connect with tools and workflows. A capable model is better at deciding when to use tools, what information to pass, and how to complete multi-step actions.
For sensitive workflows, you may prefer a local or self-hosted model instead of a cloud API model. This gives you more control over where your data goes and how it is processed.
Which Models Work Best with OpenClaw
OpenClaw can use different model providers with the provider/model format. The best setup depends on your workflow, cost, speed, and privacy needs. Do not use the most expensive model for every tiny task, unless burning a budget is the business model.
| Model / Provider | Best For | Why It Works Well with OpenClaw |
|---|---|---|
| Claude Sonnet | Best overall primary model | Strong for reasoning, writing, coding, and daily workflows |
| Claude Opus | Complex workflows | Good for research, planning, and high-value automation |
| OpenAI GPT models | General agent workflows | Reliable for tool use, structured replies, and automation |
| OpenAI Codex models | Coding workflows | Best for debugging, code review, and developer tasks |
| Gemini models | Long-context tasks | Useful for documents, summaries, and large inputs |
| OpenRouter models | Multi-model setup | Good for accessing many models and fallback options |
| Mistral models | Fast, low-cost tasks | Works well for simple replies and lightweight automation |
| Qwen models | Budget coding and reasoning | Good for structured output and technical tasks |
| DeepSeek models | Coding on a budget | Useful for code help and logic-heavy workflows |
| Kimi / Moonshot models | Long research tasks | Good for reading and summarizing large content |
| Ollama | Local/private workflows | Best when you want more control over your data |
| LM Studio | Local testing | Useful for testing models before production use |
| vLLM | Self-hosted production | Best for advanced users running their own model server |
| LiteLLM | Model routing | Helps manage multiple providers and fallbacks |
Best Way to Change Model In OpenClaw
The best way to change model in OpenClaw depends on whether you want a quick session switch, a permanent default model, or a full provider reconfiguration. OpenClaw uses the provider/model format, so use the exact model reference when setting a model.
Use this when you want to switch models for the current session without restarting OpenClaw. Very civilized, for once.
/modelTo see available models:
/model listTo select a model by number:
/model 3To select a model directly:
/model openai/gpt-5.4To check current model status:
/model statusOpenClaw docs say /model can switch the current session immediately, and /model status shows the detailed model/auth view.
Use this if you want OpenClaw to guide you through model auth, gateway, workspace, channels, skills, and health setup.
openclaw onboardThis is best for beginners or fresh installs.
Use this when OpenClaw is already installed, but you want to update credentials, provider choices, or agent defaults.
openclaw configureUse this when you intentionally want to change the default model directly.
openclaw models set provider/model-name
Example:
openclaw models set anthropic/claude-sonnet-4-6Use this when your new model needs provider authentication.
openclaw models auth login --provider <provider-id> --set-default
Example:
openclaw models auth login --provider anthropic --set-defaultThis is useful when switching to a new provider and making it the Change Model Manually in Config .
Use this only if you are comfortable editing config files, because apparently we still let humans hand-edit JSON-like config and then act surprised when commas win.
Example:
{
agents: {
defaults: {
model: {
primary: "anthropic/claude-sonnet-4-6"
}
}
}
}Use fallback models so OpenClaw can keep working if the primary model fails, slows down, or hits limits.
{
agents: {
defaults: {
model: {
primary: "anthropic/claude-sonnet-4-6",
fallbacks: [
"openai/gpt-5.4",
"google-gemini-cli/gemini-3-flash-preview"
]
}
}
}
}Fallbacks are useful for production workflows where reliability matters more than pretending one model will never fail.
How to Test If the New Model Is Working
After changing the model in OpenClaw, test it before using it for real workflows. A model can be connected but still fail at replies, tool use, speed, or workflow quality, because apparently “it runs” is now the bar.
First, confirm which model OpenClaw is using.
openclaw models statusFor chat/session-level status, use:
/model statusCheck the active model, provider, auth status, and fallback setup.
Use this to confirm the model is available in your setup.
openclaw models listTo see all models:
openclaw models list --allTo filter by provider:
openclaw models list --provider openaiSend a simple prompt:
Reply in one sentence and tell me you are working.If OpenClaw does not reply, check the model name, API key, provider auth, billing, rate limits, or gateway setup.
Test whether the model can follow simple steps.
Create a 3-step plan for organizing my daily tasks. Keep it short and practical.Check if the answer is clear, structured, relevant, and not too slow.
Run one small workflow based on your actual use case.
| Workflow Type | Test Example |
|---|---|
| Reminder agent | Create one test reminder |
| Writing assistant | Generate one short draft |
| Coding assistant | Explain one small error |
| Research assistant | Summarize one short note |
| File workflow | Sort one safe test file |
| Chat agent | Send one test channel message |
If you added fallbacks, confirm they are visible.
openclaw models statusA good setup usually has one reliable primary model and at least one cheaper or backup fallback model.
After a few tests, compare the new model with your old setup.
| Check | Good Sign | Bad Sign |
|---|---|---|
| Speed | Replies are quick | Long delays |
| Cost | Fits daily use | Too expensive |
| Quality | Follows instructions | Misses steps |
| Tool use | Uses tools correctly | Calls wrong tools |
| Reliability | Few errors | Frequent failures |
Common Errors After Changing Model in OpenClaw
Here are the most common model switching errors in OpenClaw and the correct fix for each one.
| Error | Problem | Fix |
|---|---|---|
| Model not found | The model name, provider name, or model ID is wrong. | Run openclaw models list --all, copy the exact model name, then run openclaw models set provider/model-name. |
| Provider auth error | The API key is missing, expired, invalid, or provider login is not complete. | Run openclaw models status, then reconnect with openclaw models auth login --provider provider-id --set-default. |
| Still using old model | The default model changed, but the chat session still uses another model. | Check with openclaw models status and /model status. Then set the model with openclaw models set provider/model-name. |
| Wrong chat model | The CLI model and chat session model are different. | Run /model status, then switch chat model with /model provider/model-name. |
| Slow replies | A heavy model is used for simple tasks. | Use fast models for reminders and short replies. Use stronger models only for coding, research, and complex workflows. |
| High model cost | Expensive models are used for small tasks or long prompts. | Use cheaper models for routine tasks. Check your setup with openclaw models status. |
| Fallback not working | The fallback model is missing, wrong, or not authenticated. | Run openclaw models status and make sure the fallback provider is connected. |
| Local model not working | Ollama, LM Studio, or the local model server is not running. | Start the local model server, then run openclaw models list --provider provider-id. |
