Foundation models in generative AI are a game-changer. They're a type of model that can be fine-tuned for a wide range of tasks, from text generation to image creation.

Foundation models are pre-trained on massive amounts of data, which allows them to learn general patterns and relationships that can be applied to many different tasks. This pre-training process is key to their versatility.

By leveraging these pre-trained models, developers can create new applications and services much faster and with less data than traditional methods.

Types of AI

Foundation models are a type of AI that can be fine-tuned for various tasks, but they're not the only type of AI out there. There are several other types, including Narrow or Weak AI, which is designed to perform a single task.

Narrow AI is often seen in virtual assistants like Siri and Alexa, which can only understand and respond to a limited set of commands. This type of AI is useful, but it's limited in its capabilities.

Definition of AI

Artificial intelligence (AI) is a type of machine learning that enables computers to perform tasks that typically require human intelligence, such as visual perception, speech recognition, and decision-making.

The term AI was first coined in 1956 by computer scientist John McCarthy, who organized the first AI conference at Dartmouth College.

AI systems can learn from data, identify patterns, and make predictions or decisions based on that data. They can also improve their performance over time through machine learning algorithms.

A key characteristic of AI is its ability to process and analyze vast amounts of data quickly and accurately, often in real-time. This is particularly useful in applications like medical diagnosis and financial forecasting.

AI is not the same as human intelligence, and it's not meant to replace human thought and creativity. Instead, it's designed to augment and assist human capabilities, freeing us up to focus on more complex and creative tasks.

Narrow AI

Narrow AI is designed for a specific task and context. It's not meant to be used beyond its original purpose.

A narrow AI system is trained on specific data for a specific task. For example, a bank's model for predicting the risk of default by a loan applicant.

Narrow AI models are not designed for reuse in new contexts. They can't just switch gears and become a chatbot to communicate with customers.

Some narrow AI models are unimodal, meaning they receive input based on just one type of content, like text or images.

Large Language

Large language models are a type of AI system trained on text data that can generate natural language responses to inputs or prompts.

These systems are trained on ‘text prediction tasks’, meaning they predict the likelihood of a character, word or string, based on the preceding or surrounding context. For example, language models can predict the next most likely word in a sentence given the previous paragraph.

Language models are often used in applications such as SMS, Google Docs or Microsoft Word, which make suggestions as you are writing.

Large language models (LLMs) generally refer to language models that have hundreds of millions (and at the cutting edge, hundreds of billions) of parameters, which are pretrained using billions of words of text and use a transformer neural network architecture.

Some examples of LLMs include GPT-4, which is primarily text-based and gives only text-based outputs, and Google’s PaLM-E, an embodied multimodal language model that can use multiple inputs and generate multiple outputs, including visual tasks and robotics tasks.

Here are some common text-based tasks that LLMs can perform, such as question-answering, autocomplete, translation, summarisation, etc. in response to a wide range of inputs and prompts:

  • Question-answering
  • Autocomplete
  • Translation
  • Summarisation

Model Ecosystems

Model ecosystems are artificial systems designed to mimic real-world environments and test AI models in a controlled setting. They're like miniature labs where researchers can experiment and refine their AI creations.

These ecosystems can be as simple as a simulated city or as complex as a virtual rainforest. They're used to train AI models to make decisions in different scenarios, like predicting traffic patterns or identifying plant species.

Model ecosystems help researchers identify potential issues with AI models before they're deployed in the real world. By testing and refining their models in a controlled environment, researchers can avoid costly mistakes and improve the overall performance of their AI systems.

For example, researchers used a model ecosystem to train an AI model to predict the spread of a disease in a city. The AI model was able to identify high-risk areas and suggest interventions to public health officials.

Generative AI Techniques

Generative AI techniques are the backbone of this technology, allowing us to create content based on user inputs. Generative adversarial networks (GANs) are one such technique, which have been in use since 2014 and power many Instagram photo filters and deepfake technologies.

Style transfer is another technique that allows us to transform one form of content into another. This can be seen in the image generation capabilities of OpenAI's DALL·E and Midjourney, which use natural language text prompts to generate images.

Generative pre-trained transformers (GPT) is a technique that is also used in some generative AI applications, such as chatbots and virtual assistants. Diffusion models are yet another technique that is used in generative AI, although they are not specifically mentioned in this article.

These generative AI techniques are not mutually exclusive, and can be used in combination to achieve more complex results. For example, style transfer can be used in conjunction with GANs to create more realistic images.
