OpenAI: GPT-5 Nano
Analysis Summary
OpenAI GPT-5 Nano is a multimodal text, image, and file model with a 400K context window, tool use, and function calling. At $0.05 per million input tokens and $0.40 per million output tokens, it is designed for inexpensive, high-throughput processing.
It can be considered for classification, routing, metadata generation, extraction, and other tightly specified SEO or operations tasks. The supplied intelligence measurement is low, and no coding or agentic index is provided, so it should not handle complex content strategy, autonomous coding, or sensitive reasoning without review. Its best role is a controlled first-pass model with escalation to GPT-5 Mini or a stronger system.
