From OpenAI’s own pages, 12 November 2026.

GPT-5.4 nano costs $0.20 per million input tokens and $1.25 per million output tokens on OpenAI’s own API, and $0.02 for cached input. At those prices 1,000 support replies cost $1.10, the 10th cheapest of 49 priced models on our list.

AIGROW API credit per million input / output tokens: Claude Opus 5.5 $1.60 / $8.00, Claude Fable 5.2 $3.20 / $16.00, Claude Fable 5.1 $4.00 / $20.00, GPT-6 Astra $2.50 / $12.50, Claude Sonnet 5.5 $0.80 / $4.00, GPT-6.1 Sol $0.50 / $2.50, GPT-6.1 Terra $0.25 / $1.25, Grok 4.7 $0.50 / $1.50 and Gemini 4 Argon $1.00 / $5.00. That is up to 75% below list price. See API credit

What a job costs

Three jobs, 1,000 runs of each, at the list price above, and where each puts GPT-5.4 nano among the 49 models with a list price.
