GPT 5 Nano pricing for intent detection

Quick start

Call GPT 5 Nano with the OpenAI Python SDK:

from openai import OpenAI

client = OpenAI()
response = client.chat.completions.create(
    model="gpt-5-nano",
    max_tokens=100,
    messages=[{"role": "user", "content": "Your prompt here"}]
)
# Cost: ~$0.000055 per call at standard rates
# Input:  $0.05/MTok
# Output: $0.40/MTok

How GPT 5 Nano compares on cost

Cheapest viable option: GPT 5.6 Luna at $0.000180/call (-227% less, 91/100 quality).

What drives intent detection cost

Intent classification sits in the hot path of a conversational product, so latency constrains model choice more than price does: batch processing is not available to you when the user is waiting. That makes the fast tier the natural fit on both axes. The intent list is constant and belongs in the cached prefix.

For GPT 5 Nano specifically, that means output tokens cost 8.0x more than input, at $0.40 vs $0.05 per MTok. At this use case’s 300/100 token split, output accounts for 73% of the $0.000055 per-call cost.
