Compare GPT-3.5 Turbo
Frequently Asked Questions about GPT-3.5 Turbo
How much does the GPT-3.5 Turbo API cost per 1M tokens?+
GPT-3.5 Turbo by OpenAI is priced at $0.5 per 1M input tokens and $1.5 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.25 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.
Should I use a $20/month subscription or the GPT-3.5 Turbo 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-3.5 Turbo's context window?+
GPT-3.5 Turbo features a 16K tokens context window, which equals approximately 12,289 English words or ~33 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 4,096 tokens.
Can I run GPT-3.5 Turbo locally on my own GPU (Open Weights)?+
No, GPT-3.5 Turbo 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-3.5 Turbo 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-3.5 Turbo perform on coding and reasoning benchmarks?+
GPT-3.5 Turbo achieves a composite Intelligence Index of 30/100, scoring 12.5% on SWE-bench Verified, 28% on GPQA Diamond, 56.8% on MMLU-Pro, and 1115 pts on Chatbot Arena Elo.
What is GPT-3.5 Turbo best used for?+
GPT-3.5 Turbo is best suited for: quotidien conversationnel chatbots, client support routage, et élevé-volume texte résumé. Assessment: le grand public catalyst qui brought generative artificial intelligence dans quotidien life worldwide.

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to GPT-3.5 Turbo:
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.
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.
Un standard ouvert créé par Anthropic permettant aux agents d'IA de se connecter de façon uniforme aux systèmes de fichiers locaux, aux environnements de développement et aux API tierces.
Une optimisation tarifaire et technique conservant les états d'attention des préfixes de prompts récurrents, réduisant les coûts d'entrée de 50 à 90 % tout en abaissant la latence.
Les scores de benchmarks, tarifs par token et limites évoluent rapidement. Vérifiez toujours les spécifications actuelles sur la documentation officielle du fournisseur.
