What is an LLM and What Can It Do?

A large language model (LLM) is a type of artificial intelligence that processes and generates human-like text. These models are trained on vast amounts of text data and are designed to predict and create coherent sentences. LLMs, like ChatGPT, can understand context, provide detailed answers, and carry conversations almost as fluently as a human. Their capabilities make them valuable tools across industries, enhancing productivity and improving services.

How Safe Is Autonomous Driving?

Autonomous driving technology has made significant progress in recent years, with advancements in safety features and stricter regulations shaping its development. This update provides the latest insights from 2024 on the safety of self-driving vehicles, accident statistics, ongoing challenges, and public sentiment.

This article explores the feasibility, challenges, and potential solutions for running LLMs locally.

Beyond the Teraflops: How the AI Chip in a Tesla Model 3 is Rewiring the Future of Driving

When the Tesla Model 3 first hit the streets, it was praised for its minimalist interior and electric range. Today, however, the conversation has shifted entirely to what is hidden under the hood—not the motor, but the AI computer. In the latest iterations of the Model 3, the Full Self-Driving Computer (Hardware 4) is the real engine of the vehicle. While competitors are obsessed with throwing massive numbers like 2000 TOPS onto spec sheets, Tesla is playing a different game. They are betting on extreme energy efficiency, rapid iteration cycles, and a revolutionary chip architecture that aims to do more with less. Here is a look at how powerful the AI chip in a Tesla Model 3 really is, and why raw numbers might not tell the whole story.

Will Serious LLMs Ever Run Fully On-device?

For years, the default way to use large language models has been to send prompts to a remote server and wait for an answer, but that pattern is starting to look less fixed than it once did. Chips are getting better, models are getting smaller and more efficient, and consumer devices now ship with dedicated AI accelerators. The real question isn’t whether on-device LLMs are possible—it’s what “serious” means for consumers, and which trade-offs people will accept.

What Is a Serverless App?

Serverless applications are changing how software is built and deployed. Developers no longer need to manage physical or virtual servers to run their code. Instead, they focus on writing functions and business logic while a cloud platform handles infrastructure behind the scenes.

Who Owns AI-generated Artwork?

AI-generated artwork raises a deceptively simple question: if a model was trained on millions of images made by other people, who—if anyone—owns what the model produces? The answer depends on a mix of copyright rules, contract terms, and how the artwork was created and used. It also depends on which country’s law applies, because copyright is not identical worldwide.

Will future LLMs still hallucinate?

Large language models (LLMs) often feel fluent enough to be trusted, yet they can confidently state false facts, invent citations, or misread a question. That mismatch between polished language and shaky truth is what people call “hallucination,” and it’s one of the biggest barriers between today’s chatbots and dependable assistants.

What Is Green Energy?

Green energy is often talked about as the “clean” alternative to fossil fuels, but the label can get confusing. Some energy sources are renewable but not always low-impact. Others are low-carbon yet come with trade-offs that people disagree on. To make sense of it, it helps to look at what “green” usually means in practice: energy that creates minimal pollution, produces low greenhouse gas emissions, and causes relatively limited harm to ecosystems and communities.
