Mind Reading AI? This LLM Can Turn Thoughts into Text - Promptlib #4
AI is being applied in ways that were once thought to be the stuff of science fiction; now they're decoding brain scans with 80% accuracy.
Amid another busy week in AI, researchers are increasingly discovering innovative ways to apply the technology in practical contexts. This week has been particularly exciting, with some truly groundbreaking developments being announced, including:
An LLM has been developed that can read minds without surgically implanting a chip.
A study in which medical researchers pitted ChatGPT against physicians, with surprising results.
People are generating full AI albums using famous voices like Travis Scott, Ariana Grande, and more.

AI makes non-invasive mind-reading a reality
A new AI model called a semantic decoder, has been developed at the University of Texas, Austin. It uses noninvasive scanning methods (MRI) to decode language with over 80% accuracy from a person’s thoughts for extended periods of time.
In the experiment, participants watched films as the model decoded their inner narration of the storyline:

The model, trained on hours of data obtained from an individual's brain scans while listening to podcasts, can generate a stream of text based on the participant's thoughts while listening to a new story or imagining telling a story.

While this technology has potential benefits, such as helping the disabled speak their thoughts out loud and aiding in the development of AI that understands human language and thought, it also has some scary implications.
Currently, the decoder can only catch the "gist" of a person's stream of consciousness and requires participants to lie flat in an MRI machine for hours on end. The tech also requires subject cooperation to “both train and apply the decoder”.
LLMs are transforming medicine
Just how empathetic is ChatGPT? Apparently a lot more than your family physician.
Researchers recently conducted a study to compare ChatGPT’s performance to that of real doctors using patient questions, and the results were surprising.

Across 585 evaluations, patients preferred ChatGPT 78.6% of the time over real doctors. ChatGPT was found to be more empathetic and provided better quality responses compared to physicians. These findings highlight the potential of language models to become a crucial tool in the medical industry.
In another study highlighting the limitations of the tech, ChatGPT’s performance was compared with Google and the Hospital’s post-operative care instructions.
ChatGPT was rated lowest in terms of the understandability and actionability of the advice.
But that doesn't mean AI won’t revolutionize medicine. In a review paper published in JAMA Intern Med, medical researchers claimed AI is expected to surpass the test-taking skills of the average physician in the foreseeable future despite current limitations.
Imagine a world where AI can facilitate the following tasks in medicine:
Empower patients to take control of their health information with simplified explanations from ChatGPT.
Relieve bottlenecks caused by call centers, in-basket pools, and overwhelmed clinics with ChatGPT as a front-door portal, removing the need for reception staff.
Perform laborious "chart biopsy" tasks to create succinct summaries from dense patient medical records.

ChatGPT is your study assistant
ChatGPT has officially disrupted the education system. Some schools see its value, some are banning it altogether, and others are pretending it doesn't exist (good luck with that!).
But we know ChatGPT is a powerful learning tool, if you use it right it will lead you to straight A’s and help you master new skills with less friction and frustration.
This complex prompt on GitHub for GPT-4 turns ChatGPT into a tutor that can adjust lessons to your learning ability and style.
In the documentation, the creator shows the 10 levels of depth, along with learning and communication styles, tone styles, and reasoning frameworks that can be adjusted.

You need GPT-4 for this prompt, which is only accessible via ChatGPT Plus for $20 per month. It’s important to note that some Reddit users have complained of a slow rollout of new features and a limit of 25 responses per hour.
Also, it's essential to paste in your course material as GPT's training data is vast and can lead to hallucinations. Confining the model to your course material will ensure everything you learn is accurate.
Here you can see a comparison of the depth levels:

Text-to-music is getting extremely good
This album by Travis Scott on YouTube is completely AI-generated and sounds incredible. AI music has been in the news recently as platforms like Spotify and YouTube adapt to the copyright implications of the new technology.
AI text-to-video is finally here
Ever since the popularisation of AI image generation, we’ve been anticipating video, and now one of the first instances of complex text-to-video was posted on YouTube recently. The ad, which features party-goers sipping beers and chatting with friends is extremely disturbing:

According to the publisher, the video was created using “Stable Diffusion, Midjourney, and ControlNet”.
This image may bring to mind previous unsettling AI creations, such as a 2021 depiction of a Pokemon produced by a custom-trained, state-of-the-art model at the time:

In just a few months, text-to-image technology has improved significantly and is approaching the quality of real photographs. So, by 2025, we can expect to generate high-quality films using AI.
Here’s an AI-generated Pokemon from today for comparison:
