Scripts Documentation

update-models.ts

This script automatically updates the packages/common/models.ts file with the latest OpenAI model configurations from LobeChat's GitHub repository.

What it does

1. Fetches the latest OpenAI configuration from LobeChat's repository
2. Parses the TypeScript configuration to extract chat model information
3. Generates a new models.ts file with:
   • Updated LanguageModel enum with all available models
   • ModelTokens record mapping models to their context window token counts
   • Default model selection (prioritizes latest mini models)

Usage

# Run the script
npm run update-models

# Or directly with tsx
tsx scripts/update-models.ts

Features

• ✅ Automatic parsing of TypeScript configuration files
• ✅ Error handling with detailed logging
• ✅ Smart default model selection (prefers o4-mini, gpt-4.1-mini, etc.)
• ✅ Proper enum naming (converts kebab-case to UPPER_SNAKE_CASE)
• ✅ Token count formatting with underscores for readability
• ✅ Comprehensive logging with emojis and progress indicators

Output

The script generates a clean, formatted models.ts file with:

export enum LanguageModel {
  /**
   * o3
   */
  O3 = 'o3',
  // ... more models
}

export const ModelTokens: Record<LanguageModel, number> = {
  [LanguageModel.O3]: 200_000,
  // ... more mappings
};

export const defaultModel = LanguageModel.O4_MINI;
