GPT Image 2, Nano Banana 2, and FLUX.2 lead image generation models

For image generation, there isn't a single best model, but rather a choice based on specific needs. OpenAI's GPT Image 2 offers the highest quality and best prompt adherence, though it is the most expensive and slowest. Google's Nano Banana 2 (Gemini 3.1 Flash Image) provides a strong balance of near-top quality and editing capabilities at a significantly lower cost, making it a good default choice. For those requiring open-weight models for self-hosting, FLUX.2 is the leading option, with various licensing options available. AI

IMPACT Provides a comparative analysis of leading image generation models, guiding developers and businesses in selecting the most suitable tool for their specific needs and budget.
