Foundation Models
by Stephen M. Walker II, Co-Founder / CEO
Foundation models are large-scale machine learning models that have been pre-trained on vast datasets and can be fine-tuned for a wide range of tasks, serving as a foundational layer for further application-specific training.
The Klu.ai platform supports all major foundational models, including: GPT-4, Claude 2, Mistral 7b, Llama 2, Google PaLM, and Cohere Command.
They serve as a starting point for data scientists to develop machine learning (ML) models for various applications more quickly and cost-effectively. These models are trained on a broad spectrum of generalized and unlabeled data and are capable of performing a wide variety of general tasks, such as understanding language, generating text and images, and conversing in natural language.
A unique feature of foundation models is their adaptability, allowing them to perform a wide range of tasks with high accuracy based on input prompts. Some tasks include natural language processing (NLP), question answering, and image classification. Foundation models differ from traditional ML models, which typically perform specific tasks like analyzing text for sentiment, classifying images, and forecasting trends.
Foundation models use self-supervised learning to create labels from input data, meaning they are not trained with labeled training datasets. This distinguishes them from previous ML architectures that use supervised or unsupervised learning. Examples of foundation models include large language models (LLMs) like GPT-3 and BERT, and text-to-image models like DALL-E.
These models can be fine-tuned for more specialized downstream applications, making it faster and cheaper for data scientists to develop new ML applications rather than training unique ML models from scratch.
What are examples of foundation models?
Foundation models are large deep learning neural networks trained on massive datasets. They are designed to perform a wide variety of general tasks such as understanding language, generating text and images, and conversing in natural language. These models are adaptable and can perform a wide range of tasks with a high degree of accuracy based on input prompts. Some tasks include natural language processing (NLP), question answering, and image classification.
Examples of foundation models include:

Foundation models are a significant shift in the machine learning lifecycle. They are faster and cheaper for data scientists to use pre-trained foundation models to develop new ML applications rather than train unique ML models from the ground up. They are used in various applications such as customer support, language translation, content generation, copywriting, image classification, high-resolution image creation and editing, document extraction, robotics, healthcare, and autonomous vehicles.
However, building a foundation model from scratch is expensive and requires enormous resources. For practical applications, developers need to integrate foundation models into a software stack, including tools for prompt engineering, fine-tuning, and pipeline engineering. Despite their ability to provide grammatically and factually correct answers, foundation models have difficulty comprehending the context of a prompt and aren't socially or psychologically aware.
What is unique about foundation models compared to others?
Foundation models are large deep learning neural networks trained on massive datasets. They are unique due to their adaptability and ability to perform a wide range of tasks with a high degree of accuracy based on input prompts. These tasks include natural language processing, question answering, and image classification. Foundation models are different from traditional machine learning models, which typically perform specific tasks. Instead, foundation models can be used as base models for developing more specialized downstream applications.
Foundation models are a form of generative artificial intelligence. They generate output from one or more inputs (prompts) in the form of human language instructions. These models use self-supervised learning to create labels from input data, which means they are not trained with labeled training data sets. This feature separates them from previous machine learning architectures, which use supervised or unsupervised learning.
Foundation models are pre-trained on large-scale datasets, which enables them to learn general features and patterns from diverse data sources. This pre-training allows the models to comprehensively understand language, images, or multimodal data. The knowledge gained during pre-training can then be transferred and fine-tuned for specific tasks with relatively smaller labeled datasets. This adaptability makes foundation models versatile and applicable to various tasks, enabling developers and researchers to tailor the models to their specific needs.
Foundation models provide a significant advantage in terms of time and cost savings. Once pre-training is complete, the resulting model can be reused and fine-tuned for multiple downstream tasks. This eliminates the need to train models from scratch for each new task, saving both time and computational resources.
However, foundation models, particularly those with large architectures and parameters, require significant computational resources to train and deploy. Training these models on extensive datasets can be computationally intensive and time-consuming. This poses challenges for organizations or individuals with limited access to high-performance computing infrastructure.
Examples of foundation models include GPT-4, Claude 2, and PaLM. These models have been used in various applications such as customer support, language translation, content generation, copywriting, image classification, high-resolution image creation and editing, document extraction, robotics, healthcare, and autonomous vehicles.

How are foundational models trained?
Foundation models are large machine learning models trained on vast quantities of data, often through self-supervised learning, enabling them to be adapted to a wide range of downstream tasks. The process of training a foundation model involves several steps and requires significant resources and expertise.
The first step is to collect a large and diverse dataset, which could include text or code. This dataset should cover the tasks that you want the model to be able to perform. The data then needs to be prepared, which includes cleaning the data, removing any errors, and formatting the data in a way that the model can understand.
Training a foundation model requires a significant amount of computing resources, as the models are trained on large datasets using deep learning algorithms. This process is computationally expensive and requires expertise in machine learning and AI, as there are many factors that need to be considered, such as the choice of model architecture, the hyperparameters, and the training process.
Once the model is trained, it can be fine-tuned to adapt to specific tasks or domains. Fine-tuning involves further training and changes the weights of the model, allowing it to work with domain-specific language or improve performance for specific tasks. This can be done through methods such as domain adaptation fine-tuning, which uses limited domain-specific data, or instruction-based fine-tuning, which uses labeled examples to improve performance on a specific task.
However, training a foundation model from scratch can be very expensive, with costs ranging from tens of thousands to millions of dollars, depending on factors such as the size of the model and the amount of data and computational resources required. Therefore, many businesses opt to use pre-trained models, which have already been trained on a large dataset and can be customized to perform a variety of tasks.
Training a foundation model is a complex and challenging task that requires significant resources and expertise. However, these models can provide state-of-the-art performance on a variety of tasks and can be customized to meet specific needs, making them a valuable investment for businesses looking to gain a competitive advantage in the field of AI.
What are the challenges associated with training foundation models?
Training foundation models, also known as pre-trained models, presents several challenges:
-
Data Acquisition and Curation — Foundation models require large-scale and diverse datasets for pre-training. Acquiring and curating such datasets can be a challenging task. Data collection may involve privacy concerns, copyright issues, or difficulties in obtaining labeled data for specific tasks. Ensuring the quality and representativeness of the training data is crucial to avoid biases and improve generalization.
-
Bias — Biases present in the training data can lead to biased or unfair outcomes in the model's predictions or decisions. For example, if the training data predominantly represents certain demographics or perspectives, the model may show biases towards those groups. Addressing bias requires careful data curation, diversity in the training data, and ongoing monitoring and evaluation of the model's outputs.
-
Computational Resources — Foundation models, particularly those with large architectures and parameters, require significant computational resources to train and deploy. Training these models on extensive datasets can be computationally intensive and time-consuming. This poses challenges for organizations or individuals with limited access to high-performance computing infrastructure.
-
Expertise — Training a foundation model requires expertise in machine learning and AI. There are many factors that need to be considered, such as the choice of model architecture, the hyperparameters, and the training process. These skills are scarce and very expensive.
-
Cost — The cost of training a foundation model can range from tens of thousands to millions of dollars, depending on factors such as the size of the model and the computational resources required. The high cost of training these models can be prohibitive for many organizations, making their implementation financially unattainable.
-
Unreliability and Incomprehension — Foundation models can be unreliable and incomprehensible. Despite their impressive capabilities, we currently lack a clear understanding of how they work, when they fail, and what they are even capable of due to their emergent properties.
-
Ethical and Societal Challenges — Foundation models can exacerbate historical inequities and centralize power. They also have potential negative impacts from an environmental standpoint and could have substantial labor market impacts. The legal and regulatory frameworks for the development and deployment of foundation models are also unclear.
-
Domain-Specific Tasks — Out-of-the-box foundation models trained on general knowledge may struggle on domain-specific tasks. To improve the model's performance to the level required for specific applications, additional fine-tuning or adaptation may be necessary.
Addressing these challenges requires a combination of technical expertise, careful planning, and ongoing monitoring and evaluation. It's also important to consider the ethical and societal implications of deploying these models, and to engage in ongoing dialogue about how to manage these risks effectively.
Why is foundation modeling important?
Foundation models are a form of generative artificial intelligence (AI) that are trained on massive datasets. They are large deep learning neural networks that have revolutionized the way data scientists approach machine learning (ML). Instead of developing AI from scratch, data scientists use a foundation model as a starting point to develop ML models that power new applications more quickly and cost-effectively.
Foundation models are unique due to their adaptability. They can perform a wide range of tasks with a high degree of accuracy based on input prompts.

The size and general-purpose nature of foundation models make them different from traditional ML models, which typically perform specific tasks.
Foundation modeling is important because it significantly changes the machine learning lifecycle. Although it currently costs millions of dollars to develop a foundation model from scratch, they're useful in the long run. It's faster and cheaper for data scientists to use pre-trained foundation models to develop new ML applications rather than train unique ML models from the ground up. One potential use is automating tasks and processes, especially those that require reasoning capabilities. Applications for foundation models include customer support, language translation, content generation, copywriting, image classification, high-resolution image creation and editing, document extraction, robotics, healthcare, and autonomous vehicles.
Foundation models are a form of generative AI. They generate output from one or more inputs (prompts) in the form of human language instructions. Models are based on complex neural networks including generative adversarial networks (GANs), transformers, and variational encoders. Foundation models use self-supervised learning to create labels from input data. This means no one has instructed or trained the model with labeled training data sets. This feature separates foundation models from previous ML architectures, which use supervised or unsupervised learning.
Despite the numerous benefits, foundation models also present several challenges. They require significant computational resources to train and deploy. Training these models on extensive datasets can be computationally intensive and time-consuming.
