Swiss AI Hub v0.303.0

Added

• 🖼️ New Cloud Image Generation Model: Integrated the image-generation/flux model, enabling cloud-based image
  generation capabilities via the Swiss LLM Cloud.
• ⚙️ Swiss LLM Cloud Image API Configuration: Added new environment variables (SWISS_LLM_CLOUD_IMAGE_API_BASE_URL,
  SWISS_LLM_CLOUD_IMAGE_API_KEY) to configure access to the new image generation service.

Changed

• 🚀 Image Generation Model Prioritization: Updated Docker Compose configurations to prioritize the new cloud-based
  image-generation/flux model for non-GPU environments.
• 📝 Image Prompt Expansion Logic: Disabled LLM-powered prompt expansion for image generation when using the flux
  model to accommodate its prompt length restrictions, ensuring raw prompts are passed directly.

Removed

• 🗑️ GPU-Specific Image Generation Model Placeholder: Removed the generic IMAGE_GENERATION_MODEL setting from GPU
  deployment configurations, streamlining image generation to utilize the new cloud model for non-GPU stages while GPU
  stages await dedicated local integration.
