We study whether or not including more models always improves their average …

had launched its own LLM agent framework, the NeMo Agent Toolkit (or NAT), I got really excited. We usually think of Nvidia as the company powering the entire LLM hype with its GPUs, so it’s fascinating to see them go beyond hardware and step into the software space as well. There are already plenty of LLM agent frameworks out there: …

arXiv:2512.23284v1 Announce Type: cross Abstract: Given the central role of green e-molecule imports in the European energy transition, many studies optimize import pathways and identify a single cost-optimal solution. However, cost optimality is fragile, as real-world implementation depends on regulatory, spatial, and stakeholder constraints that are difficult to represent in optimization models and can render cost-optimal designs infeasible. To address …

with AI is an effective way of increasing coding speed. AI agents can handle a lot of the simple and repetitive tasks, while you can act as an orchestrator for your agents. A problem I often encounter, however, is that I have more context in my head than an AI agent could ever have. This could, for example, be: Business …

OpenAI is looking to hire a new executive responsible for studying emerging AI-related risks in areas ranging from computer security to mental health. In a post on X, CEO Sam Altman acknowledged that AI models are “starting to present some real challenges,” including the “potential impact of models on mental health,” as well as models that are “so good at …

TechCrunch’s Equity crew is bringing 2025 to a close and getting ahead on the year to come with our annual predictions episode! Hosts Kirsten Korosec, Anthony Ha, and Rebecca Bellan were joined by Build Mode host Isabelle Johannessen to dissect the year’s biggest tech developments, from mega AI funding rounds that defied expectations to the rise of “physical AI,” and make their calls for 2026.  The group …

I was working on a script the other day, and it was driving me nuts. It worked, sure, but it was just… slow. Really slow. I had that feeling that this could be so much faster if I could figure out where the hold-up was. My first thought was to start tweaking things. I could optimise the data loading. Or …

Nvidia has struck a non-exclusive licensing agreement with AI chip competitor Groq. As part of the deal, Nvidia will hire Groq founder Jonathan Ross, president Sunny Madra, and other employees. CNBC reported that Nvidia is acquiring assets from Groq for $20 billion; Nvidia told TechCrunch that this is not an acquisition of the company and did not comment on the …

The excitement for the European startup market was hard to ignore at the annual Slush conference in Helsinki last month. But the actual data on the state of the region’s venture market shows a different reality. The upshot: The European market has not recovered from the global venture capital reset that occurred in 2022 and 2023. But there is evidence …

we all do naturally and regularly. In our personal lives, we often keep to-do lists to organise holidays, errands, and everything in between.  At work, we rely on task trackers and project plans to keep teams aligned. For developers, it is also common to leave TODO comments in the code as reminders for future changes. Unsurprisingly, LLM agents also benefit …
