OpenAI Turns to Davinci to Make GPT-3 Better
OpenAI API adds'text-davinci-003' to its list of main GPT-3 models, which can do all tasks other models can do while also ensuring high quality, longer output, and better instruction-following. Davinci is the most competent and can perform all tasks the other models can, often with fewer instructions. It works specifically well with tasks requiring in-depth knowledge of the subject matter, such as summarising texts for a specific audience and creative content development. However, the new capabilities of Davinci also require more computing resources leading to higher costs per API call and lesser speed than other models. For example, it is good at deducing solutions to various logical problems and outlining character motivations.
How Does AI Actually Work?
The Generative AI space is moving so fast it's hard to keep everything straight. At Every, we've found ourselves furiously researching the space to try to understand the technology behind this explosion in creativity. Here are three of our favorite resources to understand the most important parts of this technology wave: neural networks, transformer models, and diffusion models. Want to understand the fundamental building blocks of deep learning models? Watch this YouTube series to get some intuition for how neural networks work--and why they're so powerful. Go deeper: Read this free online book, Neural Networks and Deep Learning by Michael Nielsen to get your hands dirty building a simple neural network yourself. Transformer models are the innovation that led to GPT-3 and the current explosion of innovation in AI. Read this article to understand how they work--and how they use something called
MrSARP: A Hierarchical Deep Generative Prior for SAR Image Super-resolution
Agarwal, Tushar, Sugavanam, Nithin, Ertin, Emre
Generative models learned from training using deep learning methods can be used as priors in inverse under-determined inverse problems, including imaging from sparse set of measurements. In this paper, we present a novel hierarchical deep-generative model MrSARP for SAR imagery that can synthesize SAR images of a target at different resolutions jointly. MrSARP is trained in conjunction with a critic that scores multi resolution images jointly to decide if they are realistic images of a target at different resolutions. We show how this deep generative model can be used to retrieve the high spatial resolution image from low resolution images of the same target. The cost function of the generator is modified to improve its capability to retrieve the input parameters for a given set of resolution images. We evaluate the model's performance using the three standard error metrics used for evaluating super-resolution performance on simulated data and compare it to upsampling and sparsity based image sharpening approaches.
What is Open AI and What Does It Do? - Fronty
OpenAI is a non-profit research organization dedicated to developing and applying artificial intelligence (AI) for the benefit of humanity as a whole. Elon Musk and Sam Altman founded the company in 2015, headquartered in San Francisco, California. OpenAI was founded partly due to its founders' existential fears about the potential for a disaster caused by carelessness and misuse of general-purpose AI. The company focuses on fundamental advances in artificial intelligence and its capabilities. The company's two founders and other investors began with a $1 billion endowment. Elon Musk left the company in February 2018 due to potential conflicts with his work at Tesla, Nikola Tesla's electronics company.
AI Art Is Eating The World, And We Need To Discuss Its Wonders And Dangers
After posting the following AI-generated images, I got private replies asking the same question: "Can you tell me how you made these?" So, here I will provide the background and "how to" of creating such AI portraits, but also describe the ethical considerations and the dangers we should address right now. Generative AI – as opposed to analytical artificial intelligence – can create novel content. It not only analyzes existing datasets but it generates whole new images, text, audio, videos, and code. As the ability to generate original images based on written text emerged, it became the hottest hype in tech. It all began with the release of DALL-E 2, an improved AI art program from OpenAI.
Human creators stand to benefit as AI rewrites the rules of content creation
Among the AI-related technologies to have emerged in the past several years is generative AI--deep-learning algorithms that allow computers to generate original content, such as text, images, video, audio, and code. And demand for such content will likely jump in the coming years--Gartner predicts that by 2025, generative AI will account for 10% of all data created, compared with 1% in 2022. "Théâtre D'opéra Spatial" is an example of AI-generated content (AIGC), created with the Midjourney text-to-art generator program. Several other AI-driven art-generating programs have also emerged in 2022, capable of creating paintings from single-line text prompts. The diversity of technologies reflects a wide range of artistic styles and different user demands.
An Introduction to Poisson Flow Generative Models
Generative AI models have made great strides in the past few years. Physics-inspired Diffusion Models have ascended to state-of-the-art performance in several domains, powering models like Stable Diffusion, DALL-E 2, and Imagen. Researchers from MIT have recently unveiled a new physics-inspired generative model, this time drawing inspiration from the field of electrodynamics. This new type of model - the Poisson Flow Generative Model (PFGM) - treats the data points as charged particles. By following the electric field generated by the data points, PFGMs can create entirely novel data. PFGMs constitute an exciting foundation for new avenues of research, especially given that they are 10-20 times faster than Diffusion Models on image generation tasks, with comparable performance. In this article, we'll take a high-level look at PFGM theory before learning how to train and sample with PFGMs. After that we'll take another look at the theory, this time perfoming a deep dive starting from first principles. Then we'll look at how PFGMs stack up to other models and other results before ending with some final words. Several families of generative models have evolved throughout the development of AI. Other approaches, like GANs, cannot explicitly calculate likelihoods, but can generate very high-quality samples.
Amazon's Create With Alexa generates unique animated children's stories on Echo Show
Tools like DALL-E 2, Stable Diffusion and Midjourney, which generate images based on a few lines of text, briefly set social media ablaze this year. But Amazon's entry into the AI art world is a bit different. Create with Alexa lets children guide the creation of animated stories using a few kid-friendly prompts. Since Create with Alexa is visual storytelling, it's only available on Echo Show devices, not the company's audio-only speakers. Amazon says it works whether the device is in Amazon Kids mode or not.

The Myth of Culturally Agnostic AI Models
AI models trained on enormously large datasets, specifically large language or vision-language models, represent a phenomenon that has by far outgrown the notion of "being just a tool". Regardless of how and for what purpose such models are practically employed, they in themselves represent a valuable object of study. "In themselves" in this context includes not only all the culturally dependent patterns learned from the training data, but also the culturally dependent attempts to control, modify or erase culturally dependent patterns in the training data. Focusing on the comparative analysis of outputs from two very popular text-to-image synthesis models, DALL E 2 [1] and Stable Diffusion [2], this paper tries to tackle the pros and cons of striving towards culturally agnostic vs. culturally specific AI models. Implemented in one way or another, most commonly the "guiding principle" behind many existing text-to-image generators is the ground-breaking vision-language model CLIP and its emerging derivatives (e.g.
