AI got 300× cheaper
In March 2023 OpenAI charged $30 for a million tokens. In September 2026 its cheap model costs 10 cents.
The full story
A token is a piece of a word. AI companies charge by the million.
OpenAI's list price for 1 million tokens going in, at each launch: • GPT-4, March 2023: $30 • GPT-4 Turbo, November 2023: $10 • GPT-4o, May 2024: $5 • GPT-6 Luna, 22 September 2026: $0.10
$30 to $0.10 is 300 times cheaper in three and a half years.
How to read the picture: each circle's size is the price. The green dot is drawn at its true size.
What this does NOT say: • These are different products. GPT-4 was OpenAI's top model in 2023. Luna is its cheap model today. OpenAI's top models cost more. • This is the price for text going in. Text coming out costs more ($60 then, $0.50 now). • This is the price for companies that build on OpenAI. It is not the price of a ChatGPT subscription. • A lower price per token does not mean a lower total bill. Companies use far more tokens now.
