> Hi. What is the context length of the GPT-4 model in chatGPT? The [models page](https://platform.openai.com/docs/models/gpt-4) in the openAI documentation says chat optimized GPT-4 has a context length of 8192. While [this paper](https://arxiv.org/pdf/2303.11381.pdf) from Azure AI says that GPT-4 in chatGPT has a context length of 4096.
