opencode-chatgpt-websearch

opencode-chatgpt-websearch lets OpenCode2 run web searches using your existing ChatGPT login.

Prerequisites

• OpenCode2 with V2 plugin support
• An openai connection authenticated through ChatGPT OAuth (browser or headless login)

Install

Add the plugin to ~/.config/opencode/opencode.jsonc:

{
  "plugins": ["opencode-chatgpt-websearch"]
}

Restart OpenCode2. On the first web search, select ChatGPT (experimental) as the web-search provider.

Configuration

The default configuration uses gpt-5.6-luna with maximum reasoning. You can override it through the plugin options:

{
  "plugins": [
    {
      "package": "opencode-chatgpt-websearch",
      "options": {
        "model": "gpt-5.6-luna",
        "reasoningEffort": "max",
        "responseLength": "short",
        "maxOutputTokens": 4096,
        "timeoutMs": 25000
      }
    }
  ],
  "websearch": {
    "provider": "chatgpt"
  }
}

Setting websearch.provider is optional. It selects ChatGPT automatically instead of showing the provider chooser.
