Chat Completions

GPT-5.4 nano is the lightest and most cost-efficient model in the GPT-5.4 family, built for speed-sensitive and high-volume workloads. It supports both text and image inputs and is designed for low-latency tasks such as classification, data extraction, ranking, and sub-agent execution. The model is focused on responsiveness and efficiency rather than deep reasoning, making it ideal for pipelines that need fast and reliable results at scale. GPT-5.4 nano is a strong fit for background processing, real-time systems, and distributed agent architectures where keeping costs and latency low is essential.
