Report Period: July 3-9, 2025

The eighth Joomla! AI Framework project discussion meeting was successfully held on July 4, 2025. The meeting was attended by Benjamin Trenkle, Charvi Mehra and Shivam Rajput.

Key Accomplishments

• July 3:
  • Restructured test files architecture replacing hardcoded API keys (xyz) with centralized configuration file
  • Updated all test files to implement structured output formatting and organized test file usage
  • Reorganized Test folder with proper naming conventions for improved maintainability
• July 4:
  • Presented comprehensive work progress and results of gpt-image-1 model capabilities
  • Discussed development priorities focusing on:
    • Removing code repetition across the framework
    • Implementing input validation for all methods
    • Working on comprehensive exception handling
  • Developed and implemented ModerationInterface for comprehensive content moderation in OpenAIProvider
• July 7:
  • Integrated moderation capabilities across all content-generating methods:
    • chat() - pre-moderates user messages
    • chatWithVision() - moderates both text and image content
    • generateImage() - moderates image generation prompts
    • editImage() - moderates image editing prompts
    • speech() - moderates text-to-speech input
    • createEmbeddings() - moderates embedding input text
  • Created comprehensive moderation test suite (Tests/ModerationTest.php) with 5 test scenarios:
    • Chat moderation with clean content validation
    • Chat moderation with flagged content (violence/hate speech detection)
    • Image generation with clean prompts
    • Image generation with flagged prompts (violent imagery detection)
    • Vision moderation testing with flagged text content
• July 8:
  • Added comprehensive validation methods for image inputs across all image-related requests
  • Enhanced parameter handling for image operations:
    • buildImageRequestPayload() - added support for n, size, quality, style, response_format, and gpt-image-1 specific parameters
    • buildImageVariationPayload() - implemented n, size, response_format, and user parameters
    • buildImageEditPayload() - added n, size, quality, response_format, mask handling, and gpt-image-1 parameters
  • Eliminated code duplication by consolidating parseTranscriptionResponse() and parseTranslationResponse() into unified parseAudioTextResponse() method
• July 9:
  • Implemented comprehensive validation for all OpenAI API inputs across chat, audio, and embedding endpoints
  • Added parameter validation covering models, voices, formats, file sizes, and supported options
  • Enhanced error prevention through proactive input validation before API requests

Next Steps

• Complete exception handling implementation across all framework capabilities
• Expand validation coverage to include edge cases and error scenarios
• Implement comprehensive error recovery mechanisms for all API interactions
