OpenAI: GPT-5.4 Nano
Analysis Summary
GPT-5.4 Nano is OpenAI's compact entry in the GPT-5.4 family, and it punches well above its size class. With an intelligence index of 38.2 and a coding index of 43.9, it sits in the very strong tier for both reasoning and software tasks. Its agentic index of 59.2 is particularly strong for a nano-class model, making it a credible option for multi-step tool use and automated workflows.
The 400K context window, combined with vision, file input, tool use, and function calling, gives it broad capability breadth that suits a wide range of business workloads: document analysis, code review, customer-facing automation, and structured content generation. Instruction following is strong, with an ifbench score of 0.76. The main trade-off versus larger GPT-5.4 siblings is a meaningful gap in raw reasoning depth.
At $0.20 input and $1.25 output per million tokens, it offers strong value for a GPT-5 family model. Teams that need reliable agentic performance and multimodal capability without the cost of the full GPT-5.4 will find this a well-rounded choice.
