About GPT-o4 Mini

GPT-o4 Mini is OpenAI's most cost-efficient reasoning model, bringing the power of deliberative chain-of-thought reasoning to budget-conscious applications. It uses the same 'thinking tokens' approach as larger o-series models but at a fraction of the cost ($1.10 per million input tokens). The model excels at STEM tasks, coding challenges, and logical reasoning problems where standard language models struggle. With a 200K context window, it can process long technical documents while applying careful step-by-step analysis. O4 Mini represents OpenAI's effort to democratize advanced reasoning capabilities, making them accessible for educational platforms, coding tools, and analytical applications that previously couldn't justify the cost of full reasoning models.

Frequently Asked Questions

What is GPT-o4 Mini?
GPT-o4 Mini is OpenAI's most cost-efficient reasoning model, bringing the power of deliberative chain-of-thought reasoning to budget-conscious applications. It uses the same 'thinking tokens' approach as larger o-series models but at a fraction of the cost ($1.10 per million input tokens). The model excels at STEM tasks, coding challenges, and logical reasoning problems where standard language models struggle. With a 200K context window, it can process long technical documents while applying careful step-by-step analysis. O4 Mini represents OpenAI's effort to democratize advanced reasoning capabilities, making them accessible for educational platforms, coding tools, and analytical applications that previously couldn't justify the cost of full reasoning models.
How much does GPT-o4 Mini cost?
GPT-o4 Mini costs $1.10 per 1 million input tokens and $4.40 per 1 million output tokens. Pricing is based on token usage, making it cost-effective for both small and large-scale applications.
What is GPT-o4 Mini's context window?
GPT-o4 Mini has a context window of 200K tokens. This determines how much text the model can process in a single request — larger context windows allow the model to handle longer documents, maintain more conversation history, and reason over bigger codebases.
Is GPT-o4 Mini open source?
No, GPT-o4 Mini is a proprietary model available through OpenAI's API. Proprietary models are typically accessible via API endpoints and offer managed infrastructure, support, and regular updates from the provider.
What is GPT-o4 Mini best for?
GPT-o4 Mini is best suited for: Affordable reasoning, coding, STEM tasks. These use cases leverage the model's specific strengths in terms of capability, speed, and cost-effectiveness within OpenAI's model lineup.
