GPT-5.4 Mini API pricing
OpenAI · Mid-range price tier · Proprietary · released 2026-03. Prices in USD per 1 million tokens. Data snapshot: 2026-11-12.
A support ticket workload of 100K requests a month costs $337.50 on GPT-5.4 Mini; the next cheaper model in the Mid-range price tier for this workload, Grok 4.20, does it for $312.50. GPT-5.4 Mini has held the same list price since 2026-08-15 and is the 56th cheapest of 113 models in the Mid-range price tier. None of its 2 hosts undercuts the price we quote. It is rated a stable release but does not meet all four criteria of the FinOps Friendly badge.
- Input: $0.75 per 1M tokens
- Output: $4.50 per 1M tokens
- Batch API (in/out): $0.375 / $2.25 per 1M tokens
- Prompt-cache read: $0.075 per 1M tokens
- Context window: 400K tokens
- Arena ELO: 1412 as of 2026-11-08
Market position
On blended price ($3.375 per 1M tokens at 30% input, 70% output) it is cheaper than 51% of models in the Mid-range price tier: 56th cheapest of 113. Across every price tier it is cheaper than 29% of priced text models in the catalogue: 216th cheapest of 303. Its Arena ELO of 1412 ranks 88th of the 160 models that carry one, tied with one other, above 45% of them. With an Arena score of 1412, GPT-5.4 Mini sits below OptimNow's lowest working quality threshold, Standard (Arena 1420+), so the quality-bar method would not shortlist it for any of the 8 use cases the table prices. It is 8 points under the Standard bar (Arena 1420+), within the benchmark's 20-point noise. Each threshold is a distance below the best ranked model, which scores 1530 on Arena scores as of 8 Nov 2026.
Licence, size and capabilities
GPT-5.4 Mini is recorded here as proprietary: access is through an API, priced by the token. Its parameter count is not published. Listed capabilities: Text, Vision, Reasoning, Agents. Filling its 400K context window once costs $0.30 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 2 different hosts. 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.
The price we quote is already the cheapest of the 2 hosts: OpenAI at $0.75 input / $4.50 output per 1M tokens. All of them charge within 10% of one another.
| Host | Input $/1M | Output $/1M |
|---|---|---|
| OpenAI (model maker, price we quote) | $0.75 | $4.50 |
| Azure (price we quote) | $0.75 | $4.50 |

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 | $277 – $338 |
| Knowledge Q&A | 2,000 / 800 | $416 – $510 |
| Meeting Summary | 10,000 / 1,200 | $615 – $1.3K |

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.
