Introducing GPT-5.4 mini and nano
OpenAI Blog 4 months ago
OpenAI released GPT-5.4 mini and nano, smaller versions of its GPT-5.4 model designed for coding, tool use, and multimodal tasks. The nano variant is the smallest available model in the GPT-5.4 family, optimized for high-volume API calls and sub-agent workloads. These models allow developers to reduce latency and costs when deploying AI systems that don't require the full capabilities of the standard GPT-5.4.
