Introduction to AI Image Generation


The landscape of AI image generation has evolved dramatically. In 2025, we're seeing unprecedented quality and control in AI-generated imagery. Whether you're a designer, marketer, or content creator, understanding these tools is essential for staying competitive.


Understanding the Latest Models


Gemini 2.5 Flash Image

Google's Gemini models have become the go-to for many professional workflows. The Flash variant offers an excellent balance of speed and quality, making it perfect for iterative design work.


Best for:

  • Quick concept iterations
  • Social media content
  • Product mockups

    • Imagen 4.0

    For photorealistic results, Imagen 4.0 sets the standard. It excels at understanding complex prompts and generating images with accurate lighting, textures, and compositions.


    Best for:

  • Marketing materials
  • Product photography simulation
  • Architectural visualization

    • FLUX and Open-Source Alternatives

    The open-source community continues to push boundaries. Models like FLUX offer flexibility and customization options that commercial APIs can't match.


    Mastering Prompt Engineering


    The key to great AI-generated images lies in your prompts. Here's a framework that consistently produces professional results:


    The SPICE Framework


  • **Subject** - What is the main focus?
  • **Properties** - Describe characteristics (color, size, material)
  • **Interaction** - How does the subject interact with the environment?
  • **Context** - Where is this taking place?

    • 5. **Extras** - Technical specifications (lighting, camera angle, style)


    Professional Workflows


    Batch Processing

    For consistent brand imagery, establish a prompt template and generate variations. Quby's integrated platform makes this seamless with batch generation capabilities.


    Iterative Refinement

    Start broad and refine through multiple rounds of generation, selecting the best outputs at each stage.
