GPT-5.4 mini brings the main capabilities of GPT-5.4 to a faster and more efficient model optimized for high-volume workloads. It supports both text and image inputs, offering strong performance in reasoning, coding, and tool use while lowering latency and cost for large-scale deployment. The model is built for production environments that need the right balance between capability and efficiency, making it a strong fit for chat applications, coding assistants, and large-scale agent workflows. GPT-5.4 mini provides reliable instruction following, solid multi-step reasoning, and consistent results across a wide range of tasks with better cost efficiency.
