"textContent": "There is not a separate model name required.\n\n“Long context” is simply an increased amount of billing per token when you send an input over the previous 272k that models before gpt-5.4 had as an input limit.\n\nNow `gpt-5.4` and `gpt-5.5` can accept up to 1M context length input, with an automatic switch in pricing when you pass the previous input threshold.\n\nYou do not need to pick a special model; you only need to send more input to have your bill for the entire API call increased by 100%/50%.\n\nReminder, not only do you have a batch input file size limit of 200 MB, but your API organization will also have a token queue limit for the batch endpoint - and the usage of API limits after passing the 272k threshold of input on calls is also doubled, or when indicated a separate model in your limits, halved.",
