Price receipt
No confirmed receipt. We hold dated captures of OpenAI's pricing page, but none of them tied GPT-4.1 nano to the price above on that page, so we do not claim this number is sourced. This model is deprecated and shuts down — while it remains purchasable, confirm the current rate on the provider's page before relying on it.
Overview
Smallest and cheapest GPT-4.1 variant. Ideal for classification and simple tasks at scale.
