Is Math the Path to Chatbots That Don’t Make Stuff Up?

“Chatbots like ChatGPT from OpenAI and Gemini from Google can answer questions, write poetry, summarize news articles and generate images. But they also make mistakes that defy common sense. Sometimes, they make stuff up — a phenomenon called hallucination.

Mr. Achim, the chief executive and co-founder of a Silicon Valley start-up called Harmonic, is part of growing effort to build a new kind of A.I. that never hallucinates. Today, this technology is focused on mathematics. But many leading researchers believe they can extend the same techniques into computer programming and other areas.

Because math is a rigid discipline with formal ways of proving whether an answer is right or wrong, companies like Harmonic can build A.I. technologies that check their own answers and learn to produce reliable information.”

OpenAI Folds AI-Powered Search Engine Into ChatGPT

“OpenAI has folded a search engine into its ChatGPT chatbot.

On Thursday, the A.I. start-up unveiled what it called “ChatGPT search.” OpenAI said the latest version of its online chatbot could retrieve and deliver information from across the internet in real time, including news, stock prices and sports scores.

Other tech companies, including giants like Google and Microsoft, as well as start-ups like the San Francisco-based Perplexity, have offered similar technologies. These services augment traditional internet search engines with chatbot technology that generates text as a way of answering questions and summarizing online information.”

Incredible Generalist Robots Show Us a Future Free of Chores

“Emerging startup Physical Intelligence has no interest in building robots. Instead, the team has something better in mind: powering the hardware with the continuously learning generalist ‘brains’ of AI software, so existing machines will be able to autonomously carry out a growing amount of tasks that require precise movements and dexterity – including housework.”

Science Is Finding Ways to Regenerate Your Heart

“It is hard to mend a broken heart, but in a few years doctors might be able to do essentially that.

Scientists are closing in on ways to help patients grow new heart muscle after a heart attack, as well as new lung tissue to treat fibrosis, corneas to erase eye pain and other body parts to gain a new chance at life.

If the science works, it could represent a new approach to medicine: reversing rather than alleviating chronic illnesses.”

DNA “Printing Press” Could Quickly Store Mountains of Data

“The invention of the printing press and movable type—metal letters that can be arranged and inked—led to the Renaissance and an explosion of information that continues to this day. Now, researchers report applying the concept of movable type at the molecular level to dramatically speed up the ability to encode data in strands of DNA, an incredibly high-density medium for storing information. Although only demonstrated in the lab so far, the new approach, reported today in Nature, could energize the emerging DNA data storage industry by making it cost effective to archive vital information for decades and beyond, independent researchers say.”
