The fifth Joomla! AI Framework project discussion meeting was successfully held on June 13, 2025. The meeting was attended by Benjamin Trenkle, Charvi Mehra and Shivam Rajput.

Key Accomplishments

• June 12:
  • Conducted testing with real API keys to validate functionality
  • Researched OpenAI core capabilities, models, and endpoints for phased development approach
  • Prepared work progress presentations and defined next steps
• June 13:
  • Demonstrated basic text generation capability results and overall work progress
  • Discussed architectural shift from monolithic to capability-based approach for better organization
  • Identified current implementation gaps and proposed solutions
  • Clarified method naming strategy:
    • prompt(): Smart router system automatically determining user requirements (chat, vision, image generation)
    • ask(): Direct instructions to chat completions API for specific interactions
  • Designed interface-based capabilities architecture:
    • Specialized interfaces: ChatInterface, ModelInterface, ImageInterface
    • Implementation approach: OpenAIProvider implements multiple capability interfaces
• June 15:
  • Published progress reports on Joomla Volunteers Portal
• June 16:
  • Restructured architecture by separating capabilities into distinct interfaces
  • Created modular design based on specific AI capabilities (ChatInterface, ModelInterface, AudioInterface)
  • Added vision capabilities to ChatInterface through chatWithVision() method
  • Implemented support for both URL and base64 image inputs
• June 17:
  • Developed comprehensive vision testing with vision_openai_test.php:
    • TEST 1: Vision with URL image input
    • TEST 2: Vision with specific model selection
  • Implemented model management functionality:
    • API-based model discovery and capability filtering
    • Model compatibility validation preventing failed API calls
    • Enhanced error messaging for unsupported models
  • Created model testing suite with model_test.php covering:
    • Available models retrieval, chat/vision model filtering
    • Model support verification and capability checking
    • Model validation in actual requests
• June 18:
  • Implemented OpenAI Image Generation API integration supporting multiple approaches
  • Successfully integrated all three models (DALL-E 2, DALL-E 3, GPT-Image-1) with both base64 and URL response formats
  • Developed comprehensive image generation testing with image_generation_test.php:
    • DALL-E 3 testing (base64 and URL responses)
    • DALL-E 2 testing (base64 and URL responses)

Next Steps

• Complete remaining implementation of image interface
• Expand testing coverage for the implemented capabilities
