OpenAI’s GPT-4 with vision still has flaws, paper reveals

Posted by in categories: climatology, mobile phones, robotics/AI

When OpenAI first unveiled GPT-4, its flagship text-generating AI model, the company touted the model’s multimodality — in other words, its ability to understand the context of images as well as text. GPT-4 could caption — and even interpret — relatively complex images, OpenAI said, for example identifying a Lightning Cable adapter from a picture of a plugged-in iPhone.

But since GPT-4’s announcement in late March, OpenAI has held back the model’s image features, reportedly on fears about abuse and privacy issues. Until recently, the exact nature of those fears remained a mystery. But early this week, OpenAI published a technical paper detailing its work to mitigate the more problematic aspects of GPT-4’s image-analyzing tools.

To date, GPT-4 with vision, abbreviated “GPT-4V” by OpenAI internally, has only been used regularly by a few thousand users of Be My Eyes, an app to help low-vision and blind people navigate the environments around them. Over the past few months, however, OpenAI also began to engage with “red teamers” to probe the model for signs of unintended behavior, according to the paper.

Kolena, a startup building tools to test AI models, raises $15M

Posted by in category: robotics/AI

Kolena, a startup building tools to test, benchmark and validate the performance of AI models, today announced that it raised $15 million in a funding round led by Lobby Capital with participation from SignalFire and Bloomberg Beta.

The new cash brings Kolena’s total raised to $21 million, and will be put toward growing the company’s research team, partnering with regulatory bodies and expanding Kolena’s sales and marketing efforts, co-founder and CEO Mohamed Elgendy told TechCrunch in an email interview.

“The use cases for AI are enormous, but AI lacks trust from both builders and the public,” Elgendy said. “This technology must be rolled out in a way that makes digital experiences better, not worse. The genie isn’t going back in the bottle, but as an industry we can make sure we make the right wishes.”

Google Podcasts to shut down in 2024 with listeners migrated to YouTube Music

Posted by in category: media & arts

Google announced this morning it will be shutting down its Google Podcasts app later in 2024 as part of its broader transition to move its streaming listeners over to YouTube Music. The company earlier this year announced YouTube Music would begin supporting podcasts in the U.S., which will expand globally by year-end, and more recently said it was adding the ability for podcasters to upload their RSS feeds to YouTube also by year-end.

Today, Google says it plans on further increasing its investment in the podcast experience on YouTube Music and making it more of a destination for podcast fans with features focused on discovery, community and switching between audio podcasts and video. The latter is something rival Spotify has also been working on with its rollout of video podcast support to creators worldwide last year, along with community features like Q&As and polls.

However, to make YouTube Music the new home for podcasts, that means moving users away from the current offering, Google Podcasts. The company notes this plan reflects how people are already listening. According to Edison, about 23% of weekly podcast users in the U.S. say YouTube is their most frequently used service versus just 4% for Google Podcasts.

The Multiverse AI Is Redefining How You Get Professional Headshots

Posted by in categories: cosmology, robotics/AI

The two major problems with most AI generated human images is with teeth and fingers. Most of the AI tools don’t get these two human features correct. But The Multiverse has eliminated the problem by training their model and eliminating the need to include fingers in your headshots. The company recently announced its latest AI model, Upscale to further enhance the AI headshots.

Upscale is a new imaging model that improves lighting, skin texture, and hair which are notoriously challenging for imaging models. The results are really good. I’ve been following The Multiverse AI on socials, and have been reading great things about them, so much so that their revenue has grown more than 10 times through word of mouth in a period of last four weeks.

The Multiverse AI works by leveraging a latent diffusion model to engineer a custom headshot. According to the company, up to “80% of images look like studio quality professional headshots of the user, with the percentage depending on the quality of input images.” While there is no criteria to define and measure that percentage, I agree on the part that at least a few of the 100 generated images can be used on your LinkedIn and resume.

What’s Stopping Us From Building a Warp Drive?

A faster-than-light (FTL) warp drive would arguably represent the most important invention of all time. In 1994, Miguel Alcubierre gave all of us hope as he found a solution within general relativity that would cause the necessary warping of space. But after nearly 30 years of further study, what does our current understanding of physics say about the feasibility of a warp drive?

Elon is Right. Having to Live Forever is a Curse. Here’s How to Solve It

Posted by in categories: Elon Musk, ethics, life extension, neuroscience

Let’s say that it is a curse. The issue is he is also against life extension entirely. Maybe I want 200 years. Or 1,000. I have zero concern over a boredom problem as it is brain process which can eventually be controlled. And I am disgusted with the idea that I have to die because we might not progress very fast? Ugh.

Elon Musk has said a lot of potentially stupid stuff about aging and longevity, from saying that people shouldn’t live very long because society would ossify to advocating that we judge people based on their chronological age. Most recently, he’s taken to Twitter (aka X) to say “May you live forever is the worst possible curse once you understand deep time.” In this case though, he’s not wrong.

Brain implants may get a broadband boost with new approach

Posted by in categories: computing, neuroscience, wearables

Researchers have proposed employing wireless neural implants to execute communication between the human brain and computers.

Purdue University researchers have unveiled a new method that may enable a compact brain-implanted sensor to sense and transmit data to a wearable device shaped like headphones.
