GPT-4.1 Nano API pricing
OpenAI · Budget price tier · Proprietary · released 2025-04. Prices in USD per 1 million tokens. Data snapshot: 2026-11-12.
Deprecated. The model maker has announced retirement of this model's API · shutdown 2026-10-23 · suggested replacement: GPT-5.6 Luna. It still carries a price because hosts still serve it; treat it as a model to migrate off, not one to start on.
A support ticket workload of 100K requests a month costs $35.00 on GPT-4.1 Nano; the next cheaper model in the Budget price tier for this workload, Particle-1, does it for $32.50. GPT-4.1 Nano has held the same list price since 2026-08-15 and is the 62nd cheapest of 160 models in the Budget price tier. Only one host, Azure, sells it, so there is no second price to shop. Its maker has announced its retirement, so it is a model to migrate off rather than start on.

Licence, size and capabilities
GPT-4.1 Nano is recorded here as proprietary: access is through an API, priced by the token. Its parameter count is not published. Listed capabilities: Text, Vision, Agents. Filling its 1M context window once costs $0.10 in input tokens at list price.
Pricing by host
A host is a company that runs the model and sells it by the token: the model maker, a cloud platform like Amazon Bedrock, Azure or Vertex, or an independent host. One model, several hosts, and often several prices. This model is sold by 1 host. The price we quote elsewhere on this page is marked. We quote one host's rate so that models stay comparable; it is not a recommendation to buy there.
Azure is the only host with a published rate, $0.10 input / $0.40 output per 1M tokens, which is the price we quote.
| Host | Input $/1M | Output $/1M |
|---|---|---|
| Azure (price we quote) | $0.10 | $0.40 |

Monthly cost at 100K requests, by business use case
From the after-discounts figure (prompt caching on the cached input share, batch API for async workloads, only where OpenAI publishes those rates), which assumes you implement both, to the list price. One figure means no discount is published.

|---|---|---|
| Support Ticket | 1,500 / 500 | $29 – $35 |
| Knowledge Q&A | 2,000 / 800 | $42 – $52 |
| Meeting Summary | 10,000 / 1,200 | $72 – $148 |
| Marketing Content | 2,500 / 1,800 | $94 – $97 |

It publishes a batch rate, and that discount is conditional: when the batch discount applies.
These are list prices. Your real cost also depends on caching and batching, negotiated discounts, marketplace agreements, and the contracts you already have. OptimNow audits exactly that.
