As mentioned, GPT-5.4 will be available in ChatGPT when users select the chatbot's Thinking mode, and as GPT-5.4 Pro from the model picker. As such, this isn't a release for Free and Go users — or even Plus subscribers, for that matter. It's more for enterprise customers, and developers who rely on the company's Codex app. On that note, for API customers, OpenAI claims GPT-5.4 is its most token efficient reasoning model to date, though those tokens will cost more than their GPT-5.2 counterparts. For instance, OpenAI is pricing one million input tokens at $2.50, up from $1.75 with GPT-5.2.
