Introducing GPT-5.4 mini and nano
OpenAI Blog
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.
Why it matters
GPT-5.4 mini and nano are smaller, faster versions of GPT-5.4 optimized for coding, tool use, multimodal reasoning, and high-volume API and sub-agent workloads.
