OpenAI announced that it has implemented a new version of its GPT-4o large language model to drive its ChatGPT chatbot, but it has declined to specify exactly how the updated model differs from its predecessor.
“To be clear, this is an improvement to GPT-4o and not a new frontier model,” the company posted on X (formerly Twitter) Monday.

After allowing users to take their best guesses at defining the new iteration, which OpenAI is calling ChatGPT-4o-latest, the company added a few scant details on its Models page on Wednesday.
Described as a “dynamic model continuously updated to the current version of GPT-4o in ChatGPT,” GPT-4o-latest has a knowledge cutoff of October 2023, and can accommodate 128,000 tokens, or 96,000 words, per conversation, just as the previous GPT-40 version did. It can output 16,384 tokens, or 12,288 words, on par with the newer GPT-40-mini model and roughly quadruple what the older GPT-4o can do.
Unfortunately, hard stats like these don’t provide insight into what the new model is actually capable of, and, apparently, neither will its developers.
