Imagen 4

Imagen 4 by Google (mid 2025) is a flagship text-to-image model that balances high-quality output with practical generation speed. Released in August 2025, it generates photorealistic images in about 4 seconds, with pricing from 8 credits per image. The model delivers significant improvements in text rendering, color accuracy, and diverse art styles compared to previous generations. It supports up to 2K resolution with strong performance across photo-realistic, impressionistic, abstract, and illustration styles. This versatility makes it well-suited for general creative workflows including content creation, concept art, and visual storytelling. For workflows requiring conversational editing or reference image integration, consider NanoBanana (Gemini 2.5 Flash Image) at 6 credits, which offers multi-turn refinement capabilities.
