Foundation models are a game-changer in the field of artificial intelligence. They're pre-trained multi-task generative AI models that can be fine-tuned for various tasks.

These models are designed to learn general knowledge and patterns from large amounts of data, making them incredibly versatile. They can be used for a wide range of applications, from language translation to image generation.

Foundation models are built to be modular, allowing developers to easily swap out components and adapt them to new tasks. This makes them a valuable asset for businesses and researchers looking to get up and running quickly with AI-powered solutions.

What are Pre-trained Multi Task Generative AI Models?

Pre-trained multi task generative AI models are essentially generative AI models that have already received some training. They've been fed millions of books, websites, and Wikipedia pages to read, which gives them an understanding of the world and the connection between different words.

This training is a crucial part of what makes these models so powerful. By being pre-trained, they can focus on generating new content rather than spending time learning the basics.

The Transformer algorithm, invented by Google researchers, is the backbone of these models. It allows them to focus on the most relevant information quickly and process many tasks in parallel.

Generative AI models like GPT are based on this algorithm and are designed to guess the next word relevant to the text. They work by following the instructions given to them and using their pre-trained knowledge to make educated guesses.

Here's a key point to remember: pre-trained multi task generative AI models have no concept of truth. They can only provide plausible responses based on their training data.

Importance of Transfer Learning in Deep Learning

Transfer learning is a game-changer in deep learning, making it possible for more people to work with advanced AI models.

Building a deep neural network from scratch can be a daunting task, requiring serious expertise. However, transfer learning simplifies the process, making it more accessible to a broader range of people.

Transfer learning allows you to leverage pre-existing models and fine-tune them for a specific task, reducing the technical burden and costs associated with building a model from scratch.

By using transfer learning, you can get more bang for your engineering buck, as you're reusing a model that's already been trained on a related task or dataset.

Transfer learning brings advanced AI within reach for many more people, making it an important development in the field of deep learning.

Types of AI Models

There are two main types of AI models: foundation models and narrow AI models. Foundation models are designed to be reused in new contexts, whereas narrow AI models are trained for a specific task and context.

Foundation models can be either unimodal or multimodal. Unimodal models receive input based on just one content input type, such as text or images. Multimodal models, on the other hand, can receive input and generate content or tasks in a range of modes, like text-to-text image captioning.

Narrow AI models, as mentioned earlier, are trained on specific data for a specific task and context. They're not designed for reuse in new contexts, unlike foundation models. For example, a bank's model for predicting the risk of default by a loan applicant would not also be capable of serving as a chatbot to communicate with customers.

Here's a breakdown of the main differences between foundation models and narrow AI models:

Foundation models, like generative AI models, are pre-trained on a vast amount of data, including books, websites, and Wikipedia pages. This training gives them an understanding of the world and the connection between different words or content.

Large Models

Large Models are incredibly powerful, with hundreds of millions or even billions of parameters, which are pretrained using billions of words of text and use a transformer neural network architecture.

These models are trained on text prediction tasks, predicting the likelihood of a character, word or string based on the preceding or surrounding context.

They can perform a wide range of text-based tasks, such as question-answering, autocomplete, translation, summarization, and more, in response to a wide range of inputs and prompts.

Large Language Models (LLMs) are the basis for most foundation models today, and are increasingly multimodal, meaning they can use multiple inputs and generate multiple outputs.

For example, some models can use both text and images simultaneously as an input, and can even describe images, detect objects, or classify scenes.

Generative AI Fundamentals

Generative AI models are designed to generate content, such as text, images, or video, and can be multimodal, meaning they can handle multiple forms of content at once.

Generative AI models are pre-trained on vast amounts of data, including books, websites, and Wikipedia pages, which gives them a broad understanding of the world and the connections between different words or content.

The Transformer algorithm, invented by Google researchers, is the foundation of many generative AI models, including GPT. It allows computers to focus on the most relevant information quickly and process many tasks in parallel.

GPT, the text-generating AI model, works by guessing the next word relevant to the text, and it does this by following the instructions given to it.

Here are the key components of a generative AI model:

  • Generative: the model generates content
  • Pre-trained: the model has been trained on a large dataset
  • Transformer: the algorithm used to process the data

A pre-trained generative AI model has no concept of truth, it only knows what is likely to follow a given text, and it will give a plausible response to a question, but it may not be correct.

Narrow AI Becoming More General

Generative AI started as narrow AI, but it's acquiring new features without being specifically coded to do so.

It's fascinating to see how ChatGPT, a conversational tool based on text-generating AI, can perform multiple tasks beyond its original purpose. For example, it can rewrite a text in a different tone of voice, summarize a text, solve mathematical problems, and even correct spelling and grammar mistakes.

Rewriting a text in a different tone of voice is just one of the many new features ChatGPT has acquired. Here are some of the tasks it can now perform:

  • Summarizing a text
  • Solving mathematical problems
  • Correcting spelling and grammar mistakes
  • Translating a text into any language
  • Brainstorming ideas
  • Analyzing feelings in a text
  • Creating a reasoned argument for a problem

This is not limited to text generation; image processors like DALL-E can also create new images and perform various tasks, such as creating variations on an existing image, enlarging images, and removing the image's background.
