Estimate · tiktoken-o200k_base · ≈3.85 chars/token Auto-counts as you type
This is a chars-per-token approximation, not a real tokenizer. Actual tokens vary by language, code density, and tool-call overhead — counts are typically ±10–20% off for English prose, more for code or non-Latin scripts. For exact billing, use the vendor's official tokenizer.

Frequently asked.
Practical GPT-5.4 nano pricing questions, with OpenAI's published rates separated from workload assumptions.
Q · 01 What is the standard GPT-5.4 nano API price? +
OpenAI lists
gpt-5.4-nano at $0.20/M input tokens, $0.02/M cached input tokens, and $1.25/M output tokens. This page stores the public list price in USD and marks the source as OpenAI's pricing docs.Q · 02 How much cheaper is GPT-5.4 nano than GPT-5.4 mini? +
Under the shared 92/8 agentic blend with 82% cache hits, GPT-5.4 nano is about
$0.15/M while GPT-5.4 mini is about $0.54/M. That makes nano roughly 3.6x cheaper for the same token mix.Q · 03 How much cheaper are Batch and Flex? +
OpenAI lists Batch and Flex for
gpt-5.4-nano at half the standard rate: $0.10/M input, $0.01/M cached input, and $0.625/M output. That is the best fit for latency-tolerant bulk classification or extraction.Q · 04 Is Priority pricing available for GPT-5.4 nano? +
No Priority row is listed for
gpt-5.4-nano on OpenAI's pricing page. The Priority table lists gpt-5.5, gpt-5.4, and gpt-5.4-mini, so this page does not publish a Priority rate for nano.Q · 05 Does GPT-5.4 nano have regional pricing? +
Yes. OpenAI states that regional processing/data-residency endpoints carry a
10% uplift for gpt-5.4-nano and related GPT-5.4/5.5 models. Standard global routing uses the public standard rate.Q · 06 Does GPT-5.4 nano support computer use? +
No. OpenAI's model page lists computer use as
Not supported for gpt-5.4-nano. Use GPT-5.4 mini or GPT-5.4 when browser or desktop automation is part of the workload.Q · 07 What release date is used here? +
OpenAI's model page lists the first GPT-5.4 nano snapshot as
gpt-5.4-nano-2026-03-17. This page uses 2026-03-17 as the model release date for pricing-history purposes.Q · 08 How accurate is the tokenizer estimate? +
The live widget uses an estimated
4.875 characters per token for English text and labels the tokenizer as tiktoken-o200k_base. It is good for budget planning, but exact billing can differ by language, whitespace, code, tool calls, and image inputs.
