AI assistants that forget what you told them 5 minutes ago aren’t very helpful. While large language models (LLMs) excel at generating human-like responses, they are fundamentally stateless—they don’t retain information between interactions. This forces developers to build custom memory systems to track conversation history, remember user preferences, and maintain context across sessions, often solving…
Since the all-new ChatGPT launched on Thursday, some users have mourned the disappearance of a peppy and encouraging personality in favor of a colder, more businesslike one (a move seemingly designed to reduce unhealthy user behavior.) The backlash shows the challenge of building artificial intelligence systems that exhibit anything like real emotional intelligence. Researchers at…
Agentic AI is revolutionizing the financial services industry through its ability to make autonomous decisions and adapt in real time, moving well beyond traditional automation. Imagine an AI assistant that can analyze quarterly earnings reports, compare them against industry expectations, and generate insights about future performance. This seemingly straightforward task involves multiple complex steps: document…
At Amazon, our team builds Rufus, a generative AI-powered shopping assistant that serves millions of customers at immense scale. However, deploying Rufus at scale introduces significant challenges that must be carefully navigated. Rufus is powered by a custom-built large language model (LLM). As the model’s complexity increased, we prioritized developing scalable multi-node inference capabilities that…
The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax and wane. On the scale of a human life, nothing much seems to happen. But on a cosmic timescale, our…
Ana Faguy & Mark Poynting BBC News Watch: Timelapse captures rising glacial lakes in Alaska Some Alaskans are evacuating their homes as meltwater escapes a basin dammed by the Mendenhall Glacier – raising fears of record-breaking flooding in the US state’s capital city. The National Weather Service (NWS) office in Juneau has issued a flood…
The need for biodegradable packaging material has never been higher. Currently, most packaging is “single use” and is made with plastic materials, derived from nonrenewable sources like crude oil that take hundreds of years to decompose in the environment. On top of this, only 9% of plastic is recycled. This has resulted in the formation…
An international study surveying people in a dozen countries found that when it comes to making complex decisions, people all over the world tend to reflect on their own, rather than seek advice. Researchers from the University of Waterloo led the new study that surveyed more than 3,500 people from megacities to small Indigenous communities…
With large eyes, razor sharp teeth and a compact body built for hunting, Janjucetus dullardi is nothing like the gentle giants we know today, but this newly discovered ancient whale is one of their earliest cousins. Scientists at Museums Victoria’s Research Institute have described a new species of ancient whale from a 26-million-year-old fossil found…
One theory proposes a hidden physical realm with its own versions of particles and forces that gave birth to tiny, stable black hole-like objects that would account for all the dark matter observed today. The other theory explores whether dark matter could be a product of the universe’s own expansion, created by quantum radiation near…
