GPT-5.4 Mini and Nano: OpenAI's Models Built for the Subagent Era
OpenAI released GPT-5.4 mini and GPT-5.4 nano on March 17, 2026 — two smaller, faster models purpose-built for high-volume agentic workloads and subagent orchestration.
GPT-5.4 mini brings most of GPT-5.4's strengths to a model that runs over 2x faster. It approaches the full GPT-5.4 on SWE-Bench Pro and OSWorld-Verified, making it suitable as the primary model in coding agent pipelines. GPT-5.4 nano is the smallest and cheapest variant, priced at $0.20 per million input tokens and $1.25 per million output tokens, optimized for classification, data extraction, ranking, and supporting subagent tasks.
This release signals a significant shift in how OpenAI thinks about model deployment. Rather than one model to rule them all, the mini/nano tier explicitly targets the emerging pattern of multi-agent systems where a primary agent delegates to cheaper, faster subagents for routine work. GPT-5.4 nano's pricing makes it economically viable to run hundreds of parallel subagents.
GPT-5.4 mini is available in ChatGPT today. GPT-5.4 nano is API-only.
