GPT-5 mini launched on August 7, 2025 alongside GPT-5, GPT-5 nano, and GPT-5 pro as part of the GPT-5 model family. It occupies the cost-performance tier that typically handles the majority of production API traffic: capable enough for most tasks, affordable enough to scale.

The model inherits the GPT-5 family's architectural improvements in reasoning, coding, and instruction following while operating at reduced compute requirements. It supports a context window of 400K tokens, multimodal input, function calling, and structured outputs, providing the full feature set developers need for production applications.

If you're migrating from GPT-4o mini or GPT-4.1 mini, GPT-5 mini is the next generation of the mid-tier model. It improves quality across the board while maintaining the economics that make high-volume deployment practical.
