GPT-5.4 is tracked as official api price verified. The verified first-party rate is $2.50 input and $15.00 output per 1M tokens. The OpenRouter channel remains separate so the two routes are not mistaken for one price.
What is GPT-5.4 in this model directory?
GPT-5.4 is a OpenAI model tracked with official api price verified. This directory page brings together its current official and OpenRouter routes, context window, lifecycle notes, verification dates, example cost, and same-provider alternatives in one source-linked record.
The cost position is a directory aid, not a capability ranking. A lower sample price does not mean two models are interchangeable.
What are the GPT-5.4 input and output prices?
| Channel | Input / 1M | Cached input / 1M | Output / 1M | Verified | Source |
|---|---|---|---|---|---|
| Official direct | $2.50 | $0.25 | $15.00 | 2026-07-30 | Provider source ↗ |
| OpenRouter | $2.50 | $0.25 | $15.00 | 2026-07-30 | — |
Rates are normalized to USD per 1M tokens. This page does not replace a missing official price with an OpenRouter price.
What should you compare before choosing GPT-5.4?
For GPT-5.4, compare the direct OpenAI route with OpenRouter on the same token workload and keep any routing fee separate from the model's inference price.
Use the LLM token cost calculator with the same input, cached-input, output, and monthly-run assumptions on both channels. Follow the official and OpenRouter source links above because the displayed rates, availability, and account terms belong to separate routes.
What does GPT-5.4 cost for a typical workload?
Using 1M input tokens and 250K output tokens, the estimated cost is $6.25 through the official route and $6.25 through OpenRouter. This example is calculated from the listed token rates and does not include taxes, tools, storage, retries, or optional OpenRouter credit purchase fees.
example = (1M × input rate) + (0.25M × output rate)
monthly estimate = example × your monthly runs
Open the full workload calculator to change the token mix, cached-input percentage, monthly runs, and selected channel.
What are the context and lifecycle details?
Capacity is not a flat fee; billed tokens depend on what a request actually processes.
Standard text-token pricing is used unless the source documents another treatment.
1 official and 1 OpenRouter observations are stored for this model.
Which OpenAI models are closest for comparison?
These same-provider models are selected by similar example workload cost where comparable prices exist. Use them as navigation shortcuts, not as a claim of equivalent capability.

How is this GPT-5.4 price page maintained?
The official route uses the provider-owned source shown above. The OpenRouter route uses an explicit model-ID mapping and the exact OpenRouter record shown above. Source failures preserve the last verified record; a price-history event is added only when a verified input, cached-input, or output rate changes.

GPT-5.4 pricing questions
How much does GPT-5.4 cost per 1M tokens?
The verified first-party rate is $2.50 input and $15.00 output per 1M tokens. The mapped OpenRouter route is $2.50 input and $15.00 output per 1M tokens.
What is the GPT-5.4 example workload cost?
For 1M input tokens and 250K output tokens, the estimated cost is $6.25 through the official channel and $6.25 through OpenRouter, before any optional OpenRouter credit purchase fee.
Does GPT-5.4 have an OpenRouter route?
Yes. The route is stored separately under its OpenRouter model ID and has its own source and verification date.
What should I check before using GPT-5.4 in production?
Confirm the linked provider terms, context and long-context rules, cache behavior, rate limits, latency, tool support, data policies, and actual token usage for your workload. This page is a pricing reference, not a capability or procurement recommendation.
