Changelog Entry
🎨 Centralized model selection logic in image_generations() function to use a single model variable throughout the entire flow, reducing code duplication across OpenAI, Gemini, and ComfyUI handlers.
Description
Refactored image generation model selection to allow dynamic model override in function calls, enabling pipes and other functions to specify different image models than the globally configured default.
Changed
Centralized model selection logic in image_generations() function to use a single model variable throughout the entire flow
Modified model selection to prioritize user-provided model parameter over global configuration
Updated OpenAI, Gemini, and ComfyUI image generation handlers to use the centralized model variable
Reduced code duplication by eliminating repeated model selection logic across different image generation engines
Additional Information
This change enables better flexibility for programmatic image generation where different models may be needed for different use cases
Pipes and function calls can now override the default image model without affecting the global configuration
Maintains backward compatibility - existing behavior is preserved when no model override is provided
Improves code maintainability by centralizing model selection logic in one place
