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.
