o4-mini

OpenAI's o4-mini is a compact, multimodal reasoning model, delivering high performance with approximately 10x cost efficiency for high-volume, real-time applications.

The o4-mini model, released by OpenAI on April 16, 2025, is a high-efficiency generative pre-trained transformer (GPT) specifically engineered for rapid, cost-effective reasoning (API pricing is roughly 10x lower than the o3 model). This multimodal technology natively processes both text and images, allowing it to interpret visual elements—like whiteboard sketches or data graphs—within its 'chain-of-thought' process. It excels in complex tasks, including math, coding, and visual analysis, supporting a substantial 200,000-token context window. o4-mini is accessible to all ChatGPT users (including free-tier) and via the Chat Completions API, making advanced reasoning scalable for real-time data classification and large-scale automation.
