Imagen 4
Google · Imagen
Google's Imagen 4 image generation tier, now scheduled for API endpoint shutdown.
Overview
Freshness note: Model capabilities, limits, lifecycle dates, and pricing can change quickly. This profile is a point-in-time snapshot last verified on June 8, 2026.
Imagen 4 is Google’s dedicated text-to-image family for prompt-based visual creation in creative and product contexts. Google’s model and pricing pages still document Imagen 4 Standard, Ultra, and Fast, but the deprecation page lists the three current API endpoints with a June 24, 2026 shutdown date.
Capabilities
Imagen 4 supports high-quality text-to-image generation, style exploration, product mockups, campaign concepts, and visual iteration. The family splits into Fast, Standard, and Ultra tiers for different latency, quality, and cost envelopes, but it should now be treated as a migration target rather than a greenfield choice.
Technical Details
Imagen 4 is image-native; token context and output numbers are not the primary UI metrics in Signal Lens. contextWindow and maxOutput are stored as 0 and interpreted as N/A in listings.
Current Google API IDs:
imagen-4.0-generate-001imagen-4.0-ultra-generate-001imagen-4.0-fast-generate-001
Google’s model page lists text input, image output, a 480-token text input limit, and 1 to 4 output images for Ultra, Standard, and Fast.
Pricing & Access
Google’s current Gemini API pricing lists Imagen 4 Fast at 0.04 per image, and Imagen 4 Ultra at $0.06 per image. Access is paid-tier only through Gemini API surfaces such as AI Studio and related Google developer tooling.
The important lifecycle constraint is that all three documented Imagen 4 API endpoints are scheduled to shut down on June 24, 2026.
Best Use Cases
Use Imagen 4 only for existing integrations, migration testing, or short-window compatibility checks. For new Google image work, start with Nano Banana 2 or Nano Banana Pro instead.
Comparisons
Compared with Nano Banana 2, Imagen 4 is the older dedicated Imagen lane while Nano Banana 2 is the stable Gemini-native default for image generation. Compared with Nano Banana Pro, Imagen 4 has simpler dedicated text-to-image positioning, while Pro adds reasoning, grounding, and professional image-editing capabilities. Compared with GPT Image 2, the decision is now mostly provider ecosystem fit plus migration timing.
