Strengths

  • Fenêtre de contexte de 33K et capacité de sortie maximale de 8K tokens (Arena Elo 1360)
  • Débit rapide de 60 tokens/seconde avec une latence au premier token (TTFT) de 900 ms
  • Tarification API optimisée ($2/$20 par million de tokens) avec prise en charge du cache de prompts et des schémas JSON stricts

Limitations & Trade-offs

  • Modèle cloud propriétaire ne permettant pas le téléchargement local des poids sur serveur isolé
  • Pour les charges à très fort volume, l’activation du cache de prompts et de l’API Batch est recommandée

Editorial Assessment

Alliant un indice d’intelligence de 75/100, un contexte de 33K et un débit de 60 tok/s, Nano Banana s’impose comme une valeur sûre de la gamme Google.

Best for: Conçu pour la génération d’images haute définition, le design créatif et le rendu typographique, l’intégration RAG et les pipelines de production évolutifs.

Frequently Asked Questions about Nano Banana

How much does the Nano Banana API cost per 1M tokens?+

Nano Banana by Google is priced at $2 per 1M input tokens and $20 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.5 per 1M tokens, and asynchronous Batch API requests receive a 30% discount.

Should I use a $20/month subscription or the Nano Banana 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's context window?+

Nano Banana features a 33K tokens context window, which equals approximately 24,576 English words or ~66 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 8,192 tokens.

Can I run Nano Banana locally on my own GPU (Open Weights)?+

No, Nano Banana 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 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 perform on coding and reasoning benchmarks?+

Nano Banana achieves a composite Intelligence Index of 75/100, scoring N/A% on SWE-bench Verified, N/A% on GPQA Diamond, N/A% on MMLU-Pro, and 1360 pts on Chatbot Arena Elo.

What is Nano Banana best used for?+

Nano Banana is best suited for: Conçu pour la génération d’images haute définition, le design créatif et le rendu typographique, l’intégration RAG et les pipelines de production évolutifs.. Assessment: Alliant un indice d’intelligence de 75/100, un contexte de 33K et un débit de 60 tok/s, Nano Banana s’impose comme une valeur sûre de la gamme Google.
