TLDRIn the Open AI Dev day keynote, Sam Alman discussed the significant update to GPT-4 Turbo, which now supports a context window of up to 128,000 tokens, a substantial increase from the previous 8K tokens. This enhancement is particularly beneficial for developers needing to handle larger codebases or extensive textual analysis. Despite the API model's increased capacity, Chat GPT's context window remains approximately 8,000 tokens, equivalent to 3,000 to 4,000 words, based on a test conducted in the video. The test involved feeding Chat GPT extensive text from a Wikipedia article and a 'secret code' to assess its memory and processing capabilities within the given context window. Even surpassing 10,000 tokens, Chat GPT successfully recalled the 'secret code,' demonstrating the practicality of the upgraded context length for complex tasks.

🚀 Introduction to GPT-4 Turbo and its Enhanced Context Window

In the AI Dev day keynote, Sam Alman introduced GPT-4 Turbo, highlighting its significantly expanded context window from 8K tokens to 128K tokens, equivalent to 300 pages of a textbook. This update is particularly important for developers who require larger context windows for tasks such as coding, game development, and app building. The speech also mentioned that Chat GPT now utilizes GPT-4 Turbo, including the latest knowledge update as of April 2023. However, the exact context window size for Chat GPT post-update was not explicitly stated, prompting further investigation.

🧠 Testing Chat GPT's New Context Window Limit

The video creator conducted a series of tests to determine the new context window limit of Chat GPT after the GPT-4 Turbo update. Initially, it was found that Chat GPT claims a context window of approximately 8,000 tokens, or 3,000 to 4,000 words. Through a 'secret code' test, involving referencing a code ('mango') throughout the conversation, the creator confirmed that Chat GPT can remember and respond to the code even when the token count exceeded 10,000. This demonstrated a significant increase in the context window, which is a welcome improvement for developers and coders who require longer contexts for complex tasks.

📈 Results of Chat GPT Context Window Experiment

The experiment aimed to push the limits of Chat GPT's context window by inputting large amounts of text from a Wikipedia article about Skyfall. After surpassing 10,000 tokens and reaching up to 22,335 tokens, Chat GPT was still able to recall the 'secret code' ('mango'), indicating a substantial increase in the context window. The video also noted that the input box can handle more than 10,000 tokens at once, which was a limitation in previous versions. This suggests that users can now input entire articles, codebases, or chapters of books for analysis and manipulation, greatly expanding the capabilities and usability of Chat GPT.

Keywords

💡Open AI Dev Day

Open AI Dev Day is an event where OpenAI, the company behind AI technologies like GPT, hosts developers and enthusiasts to share updates, insights, and advancements in AI technology. In the context of the video, it's where Sam Alman discussed the new GPT-4 Turbo model and its increased context window.

💡Context Length or Window

The context length or window refers to the amount of previous text or conversation that an AI model can consider or remember when generating a response. A larger context window allows the AI to understand and respond to more complex and longer conversations or texts. In the video, it's highlighted that GPT-4 Turbo can support up to 128,000 tokens, a significant increase from previous models.

💡GPT-4 Turbo

GPT-4 Turbo is the latest iteration of the Generative Pre-trained Transformer models developed by OpenAI. It features an expanded context window, allowing it to process and generate responses for significantly longer texts. This model is a major update that enables more sophisticated and nuanced AI interactions.

💡Knowledge Cut-off Date

The knowledge cut-off date is the point in time up to which the AI model has been trained on information. It's important because it determines the currency of the data the AI can reference. In the video, it's mentioned that GPT-4 Turbo includes the latest knowledge cut-off date, which is April 2023.

💡Chat GPT

Chat GPT is a variant of the GPT models specifically designed for conversational AI, where it can engage in dialogue with users, answering questions, generating text, and more. The video explores the improvements in Chat GPT's context window with the new GPT-4 Turbo update.

💡Token

In the context of AI and natural language processing, a token is a basic unit of text, such as a word, number, or punctuation mark. The number of tokens an AI model can process at once is indicative of its context window size. The video discusses the increase in the context window by referring to the number of tokens GPT-4 Turbo can handle.

💡Secret Code Test

The secret code test is a method used in the video to measure the AI's ability to remember information over a long conversation. By providing a 'secret code' at the beginning and then referencing it later, the test assesses whether the AI can recall the information despite the length of the conversation.

💡Tokenizer

A tokenizer is a tool used in natural language processing to convert text into tokens, which are discrete units like words or sentences. It helps in understanding how much text an AI model can process by counting the number of tokens. In the video, the tokenizer is used to measure the number of tokens in the text inputted to Chat GPT.

💡Context Window Limit

The context window limit refers to the maximum amount of previous text an AI model can consider when generating a response. If the text exceeds this limit, the AI may not be able to remember or process information from the entire conversation. The video demonstrates testing the increased context window limit of Chat GPT with GPT-4 Turbo.

💡Skyfall

Skyfall is used as an example in the video to test the AI's context window. The speaker selects a random article about Skyfall, the James Bond film, to copy and paste into Chat GPT to see how much text can be processed before the AI forgets the 'secret code'.

💡Input Box Limit

The input box limit refers to the maximum amount of text that can be entered into the chat box at one time before submitting it to the AI. The video demonstrates that the input box limit for Chat GPT has been increased, allowing users to input more text at once.
