What does GPT-5.4 cost to run in a coding agent?

GPT-5.4 costs about $0.10 per average coding-agent request on our measured traffic, at list prices of $2.50 per million input and $15 per million output tokens. It scores 39 on the Artificial Analysis Intelligence Index (an estimate), 19th of the 48 models we track. Source: Artificial Analysis (artificialanalysis.ai)

List prices: OpenAI API pricing, checked 2026-10-13. Request costs: Standard Compute gateway data, 79,301 coding-agent requests from 75 users, Sep 13 to Oct 12, 2026. How we compute this

About GPT-5.4

GPT-5.4 is OpenAI's March 5, 2026 GPT-5 model, priced at $2.50/$15 per million tokens with a 1,050,000-token context. Artificial Analysis estimates 39 on its Intelligence Index, about level with GPT-5.5 (38) at half its cost per request in our measurements ($0.10 vs $0.21), and measures about 95 output tokens per second. Artificial Analysis lists it as superseded, and GPT-6.1 Sol scores 52 at a lower list price ($2/$10).

GPT-5.4 FAQ

How much does GPT-5.4 cost per coding-agent request?

$0.10 on average at list price, $10.49 per 100 requests, and $1.15 for a median 16-request session. That is 79,301 real coding-agent requests (Sep 13 to Oct 12, 2026) priced at OpenAI's list rates; the median request sent 99,534 input tokens, 87% of input was read from cache, and requests returned 698 output tokens on average.

Does GPT-5.4 charge more for long prompts?

Yes. Prompts over 272K tokens are billed at $5 per million input and $22.50 per million output tokens, on every token in the request including cache reads. 11% of the coding-agent requests we measured were that large.

How fast is GPT-5.4?

Artificial Analysis measures GPT-5.4 (Xhigh) at 95 output tokens per second, with 197 seconds to the first answer token, thinking time included, on OpenAI's API. Source: Artificial Analysis (artificialanalysis.ai).

Is GPT-5.4 good for AI agents?

Existing GPT-5.4 setups that have not moved to the GPT-6 family. On our scoring, which is calibrated to public benchmarks, it rates 6.2/10 for agentic ability and 7.7/10 for output quality. 1M-token context.

What is GPT-5.4's context window?

GPT-5.4 has a 1.1M-token context window, large enough to hold sizeable codebases or document sets in a single run. OpenAI is the maker.

Can I self-host GPT-5.4?

No. GPT-5.4 is a proprietary, hosted-only model from OpenAI. You access it through an API, such as OpenRouter, rather than running the weights yourself.

What are the downsides of GPT-5.4?

The main trade-offs: Superseded by the GPT-6 family; GPT-6.1 Sol scores higher for less; Prompts over 272K tokens bill at higher rates. It's strongest for existing GPT-5.4 setups that have not moved to the GPT-6 family.
