opencode-lmstudio

OpenCode plugin for enhanced LM Studio support with auto-detection and dynamic model discovery.

Features

• Auto-detection: Automatically detects LM Studio running on common ports (1234, 8080, 11434)
• Dynamic Model Discovery: Queries LM Studio's /v1/models endpoint to discover available models
• Smart Model Formatting: Automatically formats model names for better readability (e.g., "Qwen3 30B A3B" instead of "qwen/qwen3-30b-a3b")
• Organization Owner Extraction: Extracts and sets organizationOwner field from model IDs
• Health Check Monitoring: Verifies LM Studio is accessible before attempting operations
• Automatic Configuration: Auto-creates lmstudio provider if detected but not configured
• Model Merging: Intelligently merges discovered models with existing configuration
• Comprehensive Caching: Reduces API calls with intelligent caching system
• Error Handling: Smart error categorization with auto-fix suggestions

Installation

npm install opencode-lmstudio
# or
bun add opencode-lmstudio

Usage

Add the plugin to your opencode.json:

{
  "$schema": "https://opencode.ai/config.json",
  "plugin": [
    "opencode-lmstudio@latest"
  ],
  "provider": {
    "lmstudio": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "LM Studio (local)",
      "options": {
        "baseURL": "http://127.0.0.1:1234/v1"
      }
    }
  }
}

Auto-detection

If you don't configure the lmstudio provider, the plugin will automatically detect LM Studio if it's running on one of the common ports and create the provider configuration for you.

Manual Configuration

You can also manually configure the provider with specific models:

{
  "$schema": "https://opencode.ai/config.json",
  "plugin": [
    "opencode-lmstudio@latest"
  ],
  "provider": {
    "lmstudio": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "LM Studio (local)",
      "options": {
        "baseURL": "http://127.0.0.1:1234/v1"
      },
      "models": {
        "google/gemma-3n-e4b": {
          "name": "Gemma 3n-e4b (local)"
        }
      }
    }
  }
}

The plugin will automatically discover and add any additional models available in LM Studio that aren't already configured.

How It Works

1. On OpenCode startup, the plugin's config hook is called
2. If an lmstudio provider is found, it checks if LM Studio is accessible
3. If not configured, it attempts to auto-detect LM Studio on common ports
4. If accessible, it queries the /v1/models endpoint
5. Discovered models are merged into your configuration
6. The enhanced configuration is used for the current session

Requirements

• OpenCode with plugin support
• LM Studio running locally (default port: 1234)
• LM Studio server API accessible at http://127.0.0.1:1234/v1
