Frequently Asked Questions about GPT-4o

How much does the GPT-4o API cost per 1M tokens?+

GPT-4o by OpenAI is priced at $2.5 per 1M input tokens and $10 per 1M output tokens. With prompt caching enabled, cached input tokens cost $1.25 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.

Should I use a $20/month subscription or the GPT-4o 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-4o's context window?+

GPT-4o features a 128K tokens context window, which equals approximately 96,000 English words or ~256 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 16,384 tokens.

Can I run GPT-4o locally on my own GPU (Open Weights)?+

No, GPT-4o 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-4o 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-4o perform on coding and reasoning benchmarks?+

GPT-4o achieves a composite Intelligence Index of 41/100, scoring 38.8% on SWE-bench Verified, 53.6% on GPQA Diamond, 72.6% on MMLU-Pro, and 1286 pts on Chatbot Arena Elo.

What is GPT-4o best used for?+

GPT-4o is best suited for: Ideal para síntesis de voz natural, transcripción acústica y procesamiento de audio en tiempo real, sistemas RAG empresariales y automatización mediante API.. Assessment: Con una puntuación de inteligencia de 41/100, contexto de 128K y 105 tok/s, GPT-4o destaca como una opción sumamente sólida dentro del ecosistema de OpenAI.
