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.

Throughput is how fast the model writes (tokens per second, higher is better). Time to first token is how long before the answer starts (lower is better).
