Set up and use Coding Plan in OpenCode.

Install OpenCode

Install or update Node.js to version 18.0 or later.
To install OpenCode, run:
```
npm install -g opencode-ai
```
To verify the installation:
```
opencode -v
```

Set up Coding Plan

Create and open the config file opencode.json at one of the following paths:

macOS / Linux: ~/.config/opencode/opencode.json
Windows: C:\Users\YourUsername\.config\opencode\opencode.json

Add the following settings to the file:

Base URL: https://coding-intl.dashscope.aliyuncs.com/apps/anthropic/v1. Do not use the general Model Studio endpoint.
Note
The Base URL must end with /v1. Otherwise, a 404 Not Found error is returned.
API Key: Replace YOUR_API_KEY with your dedicated API key for Asia Pacific SE 1 (Singapore) for the Coding Plan. The key format is sk-sp-xxx.

After saving, restart OpenCode to apply the changes.

            }
        }
    }
}

Note

budgetTokens controls the maximum token budget for the model's thinking process. Setting it too low may interrupt the process.

For MiniMax-M2.5, the sum of budgetTokens and output must be less than or equal to 32768.

Usage

To start OpenCode, run:

opencode

Enter /models, search for Model Studio Coding Plan, and select a model.
