Frequently Asked Questions about Imagen 4
How much does the Imagen 4 API cost per 1M tokens?+
Imagen 4 by Google is priced at $40 per 1M input tokens and $0 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0 per 1M tokens, and asynchronous Batch API requests receive a 20% discount.
Should I use a $20/month subscription or the Imagen 4 pay-as-you-go API?+
A flat $20/month consumer subscription is predictable for daily interactive chat and manual coding. However, if you are building software, running automated workflows, or sending low-to-moderate volume with prompt caching enabled, the pay-as-you-go API is typically far more cost-effective and offers higher rate limits without manual UI caps.
How many words and pages fit in Imagen 4's context window?+
Imagen 4 features a 2K tokens context window, which equals approximately 1,536 English words or ~4 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 4,096 tokens.
Can I run Imagen 4 locally on my own GPU (Open Weights)?+
No, Imagen 4 is a proprietary closed-weights model hosted by Google. It cannot be downloaded for local GPU execution and must be accessed via Google's official API or cloud platform.
Does Google train on data sent to the Imagen 4 API, and is commercial use allowed?+
API payloads are excluded from model training by default. License tier: Proprietary Commercial API (Google Terms). Full commercial ownership of generated outputs. Supported deployment channels include: Google AI Studio API, Google Cloud Vertex AI.
How does Imagen 4 perform on coding and reasoning benchmarks?+
Imagen 4 achieves a composite Intelligence Index of 82/100, scoring N/A% on SWE-bench Verified, N/A% on GPQA Diamond, N/A% on MMLU-Pro, and 1390 pts on Chatbot Arena Elo.
What is Imagen 4 best used for?+
Imagen 4 is best suited for: professionnel advertising, print-ready media, et studio graphic design. Assessment: un de référence créatif visuel generator rivaling Midjourney et Flux.

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to Imagen 4:
L'unité textuelle de base traitée par un modèle linguistique, représentant généralement 3 à 4 caractères ou environ 0,75 mot. Par exemple, une phrase courante est découpée en plusieurs jetons.
Une suite de tests standardisés permettant d'évaluer et de comparer objectivement les performances des modèles d'IA sur des tâches ciblées (code avec SWE-bench, mathématiques avec AIME, etc.).
Le nombre maximal de jetons qu'un modèle peut traiter simultanément (entrée et sortie comprises). Une fenêtre de 1 000 000 jetons permet d'analyser environ 750 000 mots en une seule requête.
L'architecture de réseau neuronal introduite en 2017 à la base des LLM modernes, utilisant l'auto-attention pour traiter tous les jetons en parallèle plutôt que séquentiellement.
Les scores de benchmarks, tarifs par token et limites évoluent rapidement. Vérifiez toujours les spécifications actuelles sur la documentation officielle du fournisseur.
