Frequently Asked Questions about Nano Banana 2
How much does the Nano Banana 2 API cost per 1M tokens?+
Nano Banana 2 by Google is priced at $3 per 1M input tokens and $30 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.75 per 1M tokens, and asynchronous Batch API requests receive a 30% discount.
Should I use a $20/month subscription or the Nano Banana 2 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 Nano Banana 2's context window?+
Nano Banana 2 features a 131K tokens context window, which equals approximately 98,304 English words or ~262 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 16,384 tokens.
Can I run Nano Banana 2 locally on my own GPU (Open Weights)?+
No, Nano Banana 2 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 Nano Banana 2 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 Nano Banana 2 perform on coding and reasoning benchmarks?+
Nano Banana 2 achieves a composite Intelligence Index of 88/100, scoring N/A% on SWE-bench Verified, N/A% on GPQA Diamond, N/A% on MMLU-Pro, and 1455 pts on Chatbot Arena Elo.
What is Nano Banana 2 best used for?+
Nano Banana 2 is best suited for: complet-échelle comic génération, commercial advertising visuals, et film concept art. Assessment: de Google d'avant-garde visuel generator et editor dans 2026.

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to Nano Banana 2:
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.
Un modèle d'IA entraîné par apprentissage par renforcement pour allouer du temps de calcul à la réflexion logique avant d'émettre une solution, idéal pour les problèmes scientifiques et le code complexe.
Une méthode de raisonnement pas-à-pas où le modèle décompose le problème en étapes logiques intermédiaires avant de conclure, augmentant drastiquement la précision en mathématiques et programmation.
La capacité d'un LLM à déterminer quand une action externe est requise et à générer des arguments structurés pour invoquer des API, calculatrices ou bases de données avant de poursuivre.
Les scores de benchmarks, tarifs par token et limites évoluent rapidement. Vérifiez toujours les spécifications actuelles sur la documentation officielle du fournisseur.
