Frequently Asked Questions about GPT Image 2
How much does the GPT Image 2 API cost per 1M tokens?+
GPT Image 2 by OpenAI is priced at $5 per 1M input tokens and $40 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.
Should I use a $20/month subscription or the GPT Image 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 GPT Image 2's context window?+
GPT Image 2 features a 4K tokens context window, which equals approximately 3,072 English words or ~8 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 4,096 tokens.
Can I run GPT Image 2 locally on my own GPU (Open Weights)?+
No, GPT Image 2 is a proprietary closed-weights model hosted by OpenAI. It cannot be downloaded for local GPU execution and must be accessed via OpenAI's official API or cloud platform.
Does OpenAI train on data sent to the GPT Image 2 API, and is commercial use allowed?+
API payloads are excluded from model training by default. License tier: Proprietary Commercial API (OpenAI Terms). Full commercial ownership of generated outputs. Supported deployment channels include: OpenAI Platform API, Microsoft Azure OpenAI Foundry.
How does GPT Image 2 perform on coding and reasoning benchmarks?+
GPT Image 2 achieves a composite Intelligence Index of 59/100, scoring 68.5% on SWE-bench Verified, 72.5% on GPQA Diamond, 84.8% on MMLU-Pro, and 1375 pts on Chatbot Arena Elo.
What is GPT Image 2 best used for?+
GPT Image 2 is best suited for: élevé-end visuel production et campaign assets. Assessment: de 2026 leading natif image modèle pour professionnel travail.

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to GPT Image 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 réseau neuronal multimodal conçu pour analyser, raisonner et générer conjointement des données visuelles (images, schémas, interfaces) et du langage naturel au sein d'une même structure.
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.
