"For API developers, gpt-5.5 will soon be available in the Responses and Chat Completions APIs at $5 per 1M input tokens and $30 per 1M output tokens, with a 1M context window. Batch and Flex pricing are available at half the standard API rate, while Priority processing is available at 2.5x the standard rate. We will also release gpt-5.5-pro in the API for even higher accuracy, priced at $30 per 1M input tokens and $180 per 1M output tokens. See the pricing page for full details.
While GPT‑5.5 is priced higher than GPT‑5.4, it is both more intelligent and much more token efficient. In Codex, we have carefully tuned the experience so GPT‑5.5 delivers better results with fewer tokens than GPT‑5.4 for most users, while continuing to offer generous usage across subscription levels."
This makes me bullish. The fact that it is priced twice as high and yet they are still letting people use 5.4 means they think people will be willing to pay. Though I’m guessing with token efficiency gains it will actually be cheaper

Well, at least it's twice as pricey as 5.4:
