Editorial Assessment

Alliant un indice d’intelligence de 44/100, un contexte de 128K et un débit de 90 tok/s, o1-mini s’impose comme une valeur sûre de la gamme OpenAI.

Best for: Conçu pour le raisonnement logique profond, les mathématiques formelles et l’analyse scientifique, l’intégration RAG et les pipelines de production évolutifs.

Frequently Asked Questions about o1-mini

How much does the o1-mini API cost per 1M tokens?+

o1-mini by OpenAI is priced at $1.1 per 1M input tokens and $4.4 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.55 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.

Should I use a $20/month subscription or the o1-mini 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 o1-mini's context window?+

o1-mini 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 65,536 tokens.

Can I run o1-mini locally on my own GPU (Open Weights)?+

No, o1-mini 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 o1-mini 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 o1-mini perform on coding and reasoning benchmarks?+

o1-mini achieves a composite Intelligence Index of 44/100, scoring 44% on SWE-bench Verified, 68.5% on GPQA Diamond, 79% on MMLU-Pro, and 1330 pts on Chatbot Arena Elo.

What is o1-mini best used for?+

o1-mini is best suited for: Conçu pour le raisonnement logique profond, les mathématiques formelles et l’analyse scientifique, l’intégration RAG et les pipelines de production évolutifs.. Assessment: Alliant un indice d’intelligence de 44/100, un contexte de 128K et un débit de 90 tok/s, o1-mini s’impose comme une valeur sûre de la gamme OpenAI.
