OpenAI launches GPT-5.4 mini and nano with faster performance for high-volume tasks

OpenAI has launched GPT-5.4 mini and GPT-5.4 nano, two smaller models designed for fast, high-volume workloads where latency matters as much as raw capability. OpenAI says GPT-5.4 mini targets coding, tool use, multimodal reasoning, and subagent workflows, while GPT-5.4 nano focuses on simpler, cost-sensitive tasks such as classification, ranking, data extraction, and lightweight coding.
