GPT-5 mini: Advanced Intelligence for Cost-Sensitive Workloads
GPT-5 mini is a faster, highly cost-efficient counterpart to the flagship GPT-5 model, delivering near-frontier intelligence. It is specifically engineered to excel in cost-sensitive, low-latency, and high-volume environments, making it ideal for scalable applications.
As a versatile multimodal foundation, it natively accepts both text and image inputs to generate highly accurate text outputs. It is exceptionally well-suited for executing well-defined tasks and following precise developer prompts with consistent reliability.
Key Features and Capabilities
GPT-5 mini is equipped with a suite of tools and advanced capabilities designed to maximize your efficiency. It seamlessly bridges the gap between high performance and cost-effective scaling.
Massive Context Window
The model features an expansive 400,000-token context window and supports up to 128,000 maximum output tokens. This immense capacity allows developers to process vast amounts of data, analyze extensive documents, and generate highly detailed, long-form responses without losing context.
Exceptional Cost-Efficiency
Engineered specifically for high-volume workloads, it operates at a highly competitive $0.25 per million input tokens and $2.00 per million output tokens. Developers can achieve even greater savings using cached inputs, which drop the cost to just $0.025 per million tokens.
Advanced Tool Integration
GPT-5 mini natively supports function calling, structured outputs and seamless integration with the Responses API. You can leverage built-in access to web search, file search, the code interpreter and the MCP to build highly interactive agents.
Multimodal Input and Reasoning
As a true multimodal foundation, the model accepts both text and image inputs to generate highly accurate text outputs. It also includes built-in reasoning token support, empowering it to handle complex logic, data analysis, and intricate problem-solving tasks.
