Imagen 4

Imagen 4 represents the pinnacle of Google's image generation research, powering the ImageFX platform and available through Google AI Pro and Ultra subscriptions. The model builds on the success of Imagen 3 with significant improvements in photorealistic detail, texture rendering, and prompt adherence. The model is deeply integrated into Google's ecosystem, including Whisk — a visual prompting tool that uses Imagen 4 to generate images from reference images and subjects rather than text alone. This makes it uniquely powerful for creative workflows where users start from visual references rather than written descriptions. Free access is available with limited monthly generations (10 free video generations/month in ImageFX), with expanded access through Google AI Pro or Ultra subscription tiers. Imagen 4 is also available as an API for developers via Google Cloud Vertex AI.
