Frequently asked questions
How much does GPT-5.4 nano cost per 1,000 tokens?
At the published rates of $0.20 per million input tokens and $1.25 per million output tokens, a typical 1,000 token request (≈70% input, 30% output) costs about $0.0005.
Does GPT-5.4 nano offer cached input discounts?
GPT-5.4 nano drops input costs to $0.020 per million cached tokens. Using cached contexts, that same 1,000 token call totals $0.0004, a significant saving for chatbots and RAG systems.
What is the context window for GPT-5.4 nano?
GPT-5.4 nano supports up to 400,000 tokens (400K), allowing large prompts and retrieval-augmented payloads in a single call.
How fresh is the GPT-5.4 nano pricing data?
Pricing is sourced from https://openai.com/api/pricing/ and was last verified on 2026-03-19. The calculator updates automatically when models.json is refreshed.
What is GPT-5.4 nano pricing per 1M tokens?
GPT-5.4 nano is priced at $0.20 per million input tokens, $0.02 per million cached input tokens, and $1.25 per million output tokens. It targets ultra-low-cost workloads such as classification, routing, autocomplete, and extraction.
When should I choose GPT-5.4 nano?
Choose GPT-5.4 nano when prompt volume is high and each call is short or operationally simple. It fits background tasks like tagging, triage, moderation, translation, and structured extraction better than premium reasoning workloads where GPT-5.4 or GPT-5.4 mini may justify their higher price.
