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: 企业级 AI 自动化、代码研发、智能体（Agent）工作流以及 OpenAI 生态深度集成. Assessment: o1-mini 是 OpenAI 旗下极具代表性的模型，在性能、速度与 API 成本之间实现了卓越平衡。

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to o1-mini:
The basic unit of text that a language model processes, typically representing about 3 to 4 English characters or roughly 0.75 words. For example, the sentence "Artificial intelligence is fast" breaks down into about 5 tokens.
A standardized evaluation suite used to objectively measure and rank an AI model's capabilities across specific tasks — such as SWE-bench Verified for software engineering, AIME for competitive math, or MMLU for general knowledge.
The maximum number of tokens a model can consider at once — both the input it reads and the output it writes. A 1,000,000-token context window can hold roughly 750,000 English words in a single request.
An AI model trained via reinforcement learning to spend dynamic compute thinking through complex logic, math, and architectural problems before outputting a solution. Examples include OpenAI o1, o3, and DeepSeek R1.
A step-by-step reasoning technique where an AI model generates intermediate problem-solving thoughts before arriving at a final answer. Native reasoning models like OpenAI o3 and DeepSeek R1 use CoT to solve complex math and coding challenges.
The ability of a language model to recognize when an external capability is needed and output structured JSON arguments to invoke external APIs, databases, or terminal commands. The runtime executes the tool and passes results back to the model.
Benchmark scores, token prices, and rate limits evolve rapidly as AI labs release model updates. Always verify current specifications and pricing on the official provider documentation.
