Keywords

๐Ÿ’กLarge Language Models (LLMs)

Large Language Models, or LLMs, are advanced artificial intelligence systems that are trained on vast amounts of text data to perform a variety of language-related tasks. They are capable of understanding and generating human-like text, which can range from writing poetry to assisting in planning vacations. In the context of the video, LLMs represent a significant leap in AI performance and have the potential to drive substantial value in business settings.

๐Ÿ’กFoundation Models

Foundation models represent a new paradigm in AI where a single model serves as a foundational capability to drive a wide range of applications and use cases. This concept was first introduced by a team from Stanford, highlighting a shift from task-specific AI models to more versatile, general-purpose models. Foundation models are trained on unstructured data in an unsupervised manner, enabling them to transfer learnings across different tasks.

๐Ÿ’กGenerative AI

Generative AI refers to the subfield of AI focused on creating or generating new content, such as text, images, or code. This is achieved by training models on large datasets to learn patterns and relationships within the data, which they can then use to produce new, original outputs. In the context of the video, generative AI is exemplified by the capabilities of foundation models to predict and generate the next word in a sentence, thereby creating new text.

๐Ÿ’กTuning

Tuning in the context of AI refers to the process of adjusting a foundation model's parameters by introducing a small amount of labeled data. This allows the model to perform specific natural language processing tasks that it was not initially trained for. Tuning leverages the model's pre-existing knowledge from unlabeled data to achieve task-specific performance with less labeled data than traditional AI models.

๐Ÿ’กPrompting

Prompting, or prompt engineering, is a technique used with foundation models where the model is given a prompt or a piece of text, followed by a question or a task. The model then generates a response or completes the task based on the information provided in the prompt. This method allows the model to be applied to various tasks even in scenarios where labeled data is limited or non-existent.

๐Ÿ’กPerformance

In the context of AI and foundation models, performance refers to the ability of these models to accurately and efficiently complete tasks or solve problems.
