Google is actively testing multiple new variants of its Imagen image generation model, with reports indicating between three to five experimental versions currently under development. It remains unclear whether these efforts pertain to an updated Imagen 3 or a new Imagen 4 model. The company is generating notable momentum in its AI image generation capabilities, intensifying competition with OpenAI. Industry observers anticipate that Google may unveil these developments at its upcoming Google I/O event scheduled for May 20-21, 2025, although there is speculation about a potential earlier release of the new models.
