Imagine if you could ask a computer to write an essay, compose a song, draw a picture, or design a product for you. Sounds like science fiction, right? Well, not anymore. Thanks to generative AI, a type of artificial intelligence technology that can produce various types of content from data, this is becoming a reality.

How GPUs enable machines to create novel and exciting content from data


Generative AI systems can use natural language processing and computer vision to create new text, images, video, audio, code, or synthetic data in response to prompts. For example, you can use ChatGPT, a free chatbot that can generate an answer to almost any question it’s asked, or Dall-E, a tool that can create images from a text description or generate text captions from images. Generative AI has many applications and benefits for different industries and domains, such as entertainment, education, healthcare, e-commerce, etc.

But how does generative AI work? And what makes it possible? The answer is GPUs, or graphics processing units.

GPUs are essential for powering generative AI models and enabling them to learn from large amounts of data and generate high-quality content.

In this article, we will explore the latest developments and innovations in GPUs for generative AI, such as the H100 NVL, a new PCIe accelerator that can increase the performance of GPT-3 by twelve-fold over an A100. We will also discuss the current and potential use cases and benefits of generative AI for various industries and domains, as well as the ethical and social implications and risks of generative AI. By the end of this article, you will have a better understanding of how generative AI and GPUs are transforming the world of content creation and consumption.

The latest developments and innovations in GPUs for generative AI


GPUs are specialized hardware devices that can perform parallel computations much faster than CPUs. GPUs were originally designed for rendering graphics, but they have also proven to be very effective for deep learning, a branch of machine learning that uses neural networks to learn from data and generate outputs. Deep learning is the core technology behind generative AI, which can create new text, images, video, audio, code, or synthetic data from data.

To train and run generative AI models, GPUs are essential. GPUs have thousands of cores that can perform matrix operations in parallel, which are the basic operations of neural networks. GPUs also have high memory bandwidth and large memory capacity, which allow them to store and process large amounts of data efficiently. GPUs can also support various types of precision, such as 32-bit float, 16-bit float, or 8-bit integer, which can affect the speed and accuracy of generative AI models.

However, not all GPUs are equal when it comes to generative AI. Different GPUs have different features and specifications that can affect their performance and suitability for generative AI tasks. For example, some GPUs have Tensor Cores, which are specialized units that can perform mixed-precision matrix operations faster than regular cores. Tensor Cores can accelerate the performance of generative AI models that use large language models (LLMs), such as ChatGPT, which can generate natural language text from prompts. Other GPUs have RT Cores, which are specialized units that can perform ray-tracing calculations faster than regular cores. RT Cores can accelerate the performance of generative AI models that use graphics rendering techniques, such as Omniverse, which can create photorealistic virtual worlds from text inputs.

In this section, we will compare the features and specifications of different GPUs for generative AI, such as the L4, L40, A100, and H100. We will also highlight the advantages and challenges of using GPUs for generative AI, such as speed, scalability, cost, availability, etc.

Generative AI is not only a powerful technology, but also a risky one. Generative AI can pose ethical and social implications and risks for individuals, organizations, and society at large. Some of these implications and risks include:

  • Privacy and surveillance: Generative AI can be used to collect, analyze, and exploit personal data without consent or transparency. Generative AI can also be used to create synthetic media, such as images, videos, and audio, that can impersonate or manipulate people’s identities, behaviors, or opinions. Such AI-generated content can be difficult or impossible to distinguish from real media, posing serious threats to trust, security, and democracy.
  • Bias and discrimination: Generative AI can be influenced by human biases that are embedded in the data, algorithms, or systems that are used to train or run them. Generative AI can also amplify or create new biases that are not present in the original data or algorithms. Such biases can lead to unfair or harmful outcomes for certain groups or individuals based on their characteristics, such as race, gender, age, etc.
  • Accountability and responsibility: Generative AI can be complex and opaque, making it difficult to understand how they work or why they produce certain outputs. Generative AI can also be autonomous and adaptive, making it difficult to control or predict behaviors or consequences. Such complexity and opacity can raise challenges for assigning accountability and responsibility for the actions or outcomes of generative AI systems.
  • Creativity and originality: Generative AI can challenge the notions of creativity and originality by producing content that mimics or surpasses human-generated content. Generative AI can also raise questions about the ownership and authorship of the content they generate, as well as the intellectual property rights and moral rights of the creators and users of such content.
  • Human dignity and agency: Generative AI can affect human dignity and agency by replacing or augmenting human roles and functions in various domains. Generative AI can also influence or manipulate human emotions, preferences, or decisions by generating persuasive or deceptive content. Such effects can impact the autonomy, self-worth, and well-being of humans.
  • Social norms and values: Generative AI can shape social norms and values by creating content that reflects or challenges the existing cultural, moral, or ethical standards. Generative AI can also create content that promotes or undermines certain social causes or movements. Such impacts can affect the social cohesion, diversity, and justice of society.
