Mastering 3 Methods for Switching Models in OpenClaw: A Comprehensive Guide from Claude Sonnet 4.6 to GPT-5.4-mini

When using OpenClaw, many users run into a common question: "The current model is too expensive or just not the right fit—how do I switch to another one?" For example, if you're currently using the claude-sonnet-4-6 via Anthropic Messages mode and burning through tokens, you might want to switch to the more budget-friendly gpt-5.4-mini. Do you need to run openclaw onboard all over again?

The answer is: Absolutely not. OpenClaw provides 3 flexible ways to switch models, and you can get it done in as little as 10 seconds.

Key Takeaway: By the end of this article, you'll master every method for switching models in OpenClaw, know how to choose the best approach for your specific scenario, and learn how to add custom Providers for unified multi-model management.

Core Points for Switching Models in OpenClaw

Before diving into the steps, let's look at the core mechanism behind OpenClaw's model switching. OpenClaw is a model-agnostic platform that connects to various AI providers via Provider configurations.

Prerequisites for Switching Models

Before you switch, make sure you've met these requirements:

1. OpenClaw is installed and onboarded: You must have run openclaw onboard during initial setup.
2. Target model API key is configured: For example, if you're switching to GPT-5.4-mini, you need an OpenAI API key.
3. Gateway service is running: Confirm the service status with openclaw status.

# Check OpenClaw status
openclaw status

# If the gateway isn't running, start it
openclaw gateway start

🎯 Pro Tip: If you need to use API keys for multiple models simultaneously, you can use the APIYI (apiyi.com) platform to get a unified API interface. A single key allows you to invoke mainstream models like Claude, GPT, and Gemini, saving you the hassle of registering and managing multiple API keys separately.

OpenClaw Model Switching Method 1: Real-time Switching via /model Command

This is the fastest and easiest way to switch models, perfect for quick tests or swapping models on the fly during a conversation.

Basic Syntax

In any OpenClaw chat interface, simply type:

/model openai/gpt-5.4-mini

It’s that simple—the command takes effect immediately, and your current conversation will start using GPT-5.4-mini.

Complete Command Examples for OpenClaw

Features of the /model Command

Pros:

• Takes effect instantly, no need to restart any services.
• Switch anytime during a chat, great for A/B testing different models.
• Doesn't affect the default model settings in your configuration file.

Cons:

• Only valid for the current session; new conversations will revert to the default model.
• Does not modify the configuration file, so changes are lost after a restart.

Practical Demonstration

Suppose you're currently using claude-sonnet-4-6 and want to switch to gpt-5.4-mini:

Step 1: Confirm the current model

# Type in OpenClaw chat
/model

# Output example:
# Current model: anthropic/claude-sonnet-4-6
# Provider: anthropic
# API type: anthropic-messages

Step 2: Execute the switch

/model openai/gpt-5.4-mini

# Output example:
# ✅ Model switched to: openai/gpt-5.4-mini
# Provider: openai
# API type: openai-completions

Step 3: Verify the switch

Send a message directly and observe if the response comes from the new model. You can ask "What model are you?" to confirm.

💡 Pro Tip: If you get a prompt saying the API key is not configured, it means you haven't set up the key for that target provider yet. Refer to the "Method 2: Edit Configuration File" section below to add it.

OpenClaw Model Switching Method 2: Persistent Configuration

If you want your model switch to be permanent (so it's used every time you start OpenClaw), you need to modify the configuration file. This is the recommended approach for daily use.

Configuration File Location

The main configuration file for OpenClaw is located at:

~/.openclaw/openclaw.json

You can open it with any text editor, or use the built-in OpenClaw command:

# Use the built-in config editor
openclaw configure

# Or open directly with your editor
code ~/.openclaw/openclaw.json    # VS Code
vim ~/.openclaw/openclaw.json     # Vim
nano ~/.openclaw/openclaw.json    # Nano

Understanding the OpenClaw Configuration Structure

The config file is in standard JSON format. Here are the core fields related to model switching:

{
  "agents": {
    "defaults": {
      "model": {
        "primary": "anthropic/claude-sonnet-4-6"
      }
    }
  },
  "models": {
    "providers": {
      "anthropic": {
        "apiKey": "sk-ant-xxxxx",
        "api": "anthropic-messages",
        "models": ["claude-sonnet-4-6", "claude-opus-4-6", "claude-haiku-4-5"]
      },
      "openai": {
        "apiKey": "sk-xxxxx",
        "api": "openai-completions",
        "models": ["gpt-5.4-mini", "gpt-5.2", "o3-mini"]
      }
    }
  }
}

Step-by-Step: Switching from Claude Sonnet to GPT-5.4-mini

Step 1: Open the configuration file

openclaw configure

Step 2: Ensure the OpenAI Provider is configured

Check if openai exists under models.providers. If not, add the following:

"openai": {
  "apiKey": "sk-your-openai-key",
  "api": "openai-completions",
  "models": ["gpt-5.4-mini", "gpt-5.2"]
}

Step 3: Change the default model

Update the value of agents.defaults.model.primary from anthropic/claude-sonnet-4-6 to openai/gpt-5.4-mini:

{
  "agents": {
    "defaults": {
      "model": {
        "primary": "openai/gpt-5.4-mini"
      }
    }
  }
}

Step 4: Save the file and restart the Gateway

# Restart the gateway to apply changes
openclaw gateway restart

# Verify status
openclaw status

Step 5: Verify the configuration

# Use the doctor command to check if the config is correct
openclaw doctor --fix

🚀 Quick Start: If you don't want to manage multiple API keys for OpenAI, Anthropic, Google, etc., we recommend using the APIYI (apiyi.com) platform. You can access all mainstream models through a single OpenAI-compatible interface with just one API key, making configuration much simpler.

Understanding API Types in the OpenClaw Config

This is a common point of confusion. OpenClaw supports two API protocol types:

Key Point: When switching models, the API type will automatically follow the provider configuration. You don't need to specify the API type manually; just ensure the api field for the provider is configured correctly.

OpenClaw Model Switching Method 3: Dashboard Visual Interface

For users who prefer not to use the command line, OpenClaw provides a Web Dashboard, allowing you to manage model configurations through a graphical interface.

Launching the Dashboard

openclaw dashboard

Once executed, it will automatically open http://127.0.0.1:18789/ in your browser, which is the local Web management interface for OpenClaw.

Steps to Switch Models in the Dashboard

Step 1: After opening the Dashboard, locate the Settings option in the left navigation bar.

Step 2: Navigate to the Models or Agents configuration page.

Step 3: In the model list, find the Default Model option.

Step 4: Select your target model from the dropdown menu (e.g., openai/gpt-5.4-mini).

Step 5: Click Save to apply your configuration.

Step 6: The Dashboard will prompt you to restart the Gateway; confirm to proceed.

Advantages of the Dashboard

💰 Cost Optimization: The Dashboard also lets you intuitively view the usage volume and token consumption for each model. If you find that Claude Sonnet 4.6 is getting expensive, you can check the pricing comparison for different models on APIYI (apiyi.com) to find a more cost-effective alternative.

Advanced OpenClaw Model Switching: Adding Custom Providers

If you want to use a third-party platform like APIYI to manage multiple models centrally, you'll need to add a custom provider in your configuration file.

Why Use a Custom Provider?

Example: Configuring a Custom Provider

Add the following to models.providers in your ~/.openclaw/openclaw.json:

{
  "models": {
    "providers": {
      "apiyi": {
        "baseUrl": "https://api.apiyi.com/v1",
        "apiKey": "sk-your-APIYI-key",
        "api": "openai-completions",
        "models": [
          "claude-sonnet-4-6",
          "claude-opus-4-6",
          "gpt-5.4-mini",
          "gpt-5.2",
          "gemini-3-pro-preview"
        ]
      }
    }
  }
}

Once configured, switching models is as simple as:

/model apiyi/gpt-5.4-mini
/model apiyi/claude-sonnet-4-6
/model apiyi/gemini-3-pro-preview

All models are invoked through the same provider, so there's no need to switch API keys or reconfigure providers.

{
  "agents": {
    "defaults": {
      "model": {
        "primary": "apiyi/gpt-5.4-mini"
      },
      "sandbox": {
        "enabled": true
      }
    }
  },
  "models": {
    "providers": {
      "anthropic": {
        "apiKey": "sk-ant-xxxxx",
        "api": "anthropic-messages",
        "models": ["claude-sonnet-4-6", "claude-opus-4-6"]
      },
      "openai": {
        "apiKey": "sk-xxxxx",
        "api": "openai-completions",
        "models": ["gpt-5.4-mini", "gpt-5.2"]
      },
      "apiyi": {
        "baseUrl": "https://api.apiyi.com/v1",
        "apiKey": "sk-your-APIYI-key",
        "api": "openai-completions",
        "models": [
          "claude-sonnet-4-6",
          "claude-opus-4-6",
          "gpt-5.4-mini",
          "gpt-5.2",
          "gemini-3-pro-preview",
          "qwen-max"
        ]
      },
      "google": {
        "apiKey": "AIza-xxxxx",
        "api": "openai-completions",
        "models": ["gemini-3-pro-preview"]
      }
    }
  },
  "channels": {
    "telegram": { "enabled": true },
    "discord": { "enabled": false }
  }
}

Setting a Custom Provider as the Default Model

{
  "agents": {
    "defaults": {
      "model": {
        "primary": "apiyi/gpt-5.4-mini"
      }
    }
  }
}

After saving, run:

openclaw gateway restart

🎯 Technical Tip: The benefit of using a custom provider is that model switching becomes much more flexible. Through an aggregation platform like APIYI (apiyi.com), you can switch between models from different vendors like Claude, GPT, and Gemini in OpenClaw with a single command, without having to modify your provider configuration every time.

Comparing the 3 Ways to Switch Models in OpenClaw
