Large Language Models (LLMs)

Large Language Models (LLMs) are advanced AI systems designed to process and understand human language. They are typically used for a variety of tasks such as text generation, translation, and summarization. In the video, LLMs are central to the discussion as they are being pulled onto the client environment for local execution, which is a shift from the traditional cloud-hosted approach.

API Calls

API (Application Programming Interface) calls are requests made to an application or service for a specific task. In the context of the video, developers traditionally interacted with LLMs by sending API calls to cloud-hosted services to receive responses. However, the video discusses the limitations of this approach and introduces a shift towards local model execution.

WebML

WebML refers to the use of machine learning models within web browsers. It is mentioned in the video as a solution for running LLMs on the client side. WebML allows for the use of libraries like TensorFlow.js to run quantized versions of models in the browser, enabling real-time inferences without the need for server communication.

Quantized Models

Quantized models are machine learning models that have been optimized for size and speed by reducing the precision of their weights. In the video, these models are highlighted as a way to make LLMs more accessible for client-side applications by reducing their file size to around 100 MB, thus enabling them to be stored in browser cache and run inferences locally.

Client-Side Rendering

Client-side rendering refers to the process of generating a web page or web application directly on the user's device without the need for server-side processing. The video discusses the importance of client-side rendering for applications that require real-time responses, such as live captioning plugins for video calling apps.

Sensitivity of Data
