Pricing position within OpenAI
GPT-4.1 Nano is the cheapest active model in OpenAI's lineup at $0.10/1M input — no sibling undercuts it. The most expensive sibling costs $20.00/1M (19900% more). At scale, routing high-volume calls here vs the flagship saves significantly.
When GPT-4.1 Nano is worth the cost
GPT-4.1 Nano is used for general-purpose text tasks — chat, summarization, drafting, classification, and extraction. Function calling extends it to agent-style workflows where it invokes external APIs. For specialized workloads (coding, reasoning, vision), a purpose-tuned sibling may perform better.
Cost vs sibling models
What makes GPT-4.1 Nano different from sibling models: compared to GPT-5.5 ($4.90/1M more expensive, 256K vs 1M context (smaller)); GPT-5.4 ($2.40/1M more expensive, 256K vs 1M context (smaller)); GPT-4.1 ($1.90/1M more expensive, same 1M context). Choose GPT-4.1 Nano when cost per token is the priority.
Real-world cost scenarios
Real-world deployments: customer support chatbots, content drafting and summarization, classification pipelines, and extraction workflows. GPT-4.1 Nano handles the standard text-in/text-out case reliably — route specialized tasks (vision, coding, reasoning) to purpose-tuned siblings.
