What is the ChatGPT Context Window?
The ‘context window’ of an AI model refers to its memory span which determines the amount of previous information it can use while formulating a response. With OpenAI’s API upgrade, ChatGPT has jumped from a context window of 4K tokens to a whopping 16K tokens. It’s like upgrading the chatbot’s brain to remember and process four times more information at once!
My Experiments with 16K Tokens
Using my API access to GPT-3.5 Turbo, I meticulously tested this exciting feature by feeding in data chunks that exceeded the earlier 4K token limit but fell within the updated range of 16K. Think of it as working with an AI librarian who can speed-read an entire book and accurately remember every detail you ask about!
The astoundingly accurate recall and comprehension exhibited by the AI model was nothing short of impressive. With this expanded memory window, ChatGPT could answer questions accurately even if asked several thousand tokens after presenting information.
ChatGPT Function Calls
Not just users like me, but developers too are caught up in the buzz around ‘steerable API models’ – another noteworthy update alongside increased context windows. Picture these as highly sophisticated self-driving cars navigating the intricate roads of language modeling with precision. This really interesting from a prompt engineering perspective.

Allowing developers to guide and control responses effectively using function calls in system messages fosters better system steerability while executing complex tasks, making it incredibly potent in improving interactions in applications powered by ChatGPT-3.5 Turbo.
ChatGPT Lower API Prices
Adding to this excitement are lowered costs for using these updated models – a testament to OpenAI’s commitment towards increased efficiency. Developers can now use these enhanced capabilities without burning a hole in their pockets, making advancements in AI technology more accessible than ever.
