Microsoft, Anthropic, and NVIDIA are setting a bar for cloud infrastructure investment and AI model availability with a new compute alliance. This agreement signals a divergence from single-model dependency toward a diversified, hardware-optimised ecosystem, altering […]
Remember pay phones? Those relics of telecom’s distant past were once everywhere—on many busy street corners, in bars and restaurants, even built into airliners’ seatbacks. Now, an engineer in Vermont is aiming to give the […]
AI engineers often chase performance by scaling up LLM parameters and data, but the trend toward smaller, more efficient, and better-focused models has accelerated. The Phi-4 fine-tuning methodology is the cleanest public example of a […]
When I first wrote “Vector databases: Shiny object syndrome and the case of a missing unicorn” in March 2024, the industry was awash in hype. Vector databases were positioned as the next big thing — […]
Agentic AI browsers are moving the model from ‘answering about the web’ to operating on the web. In 2025, four AI browsers define this space: OpenAI’s ChatGPT Atlas, Microsoft Edge with Copilot Mode, The Browser […]
Aspiring engineers from 191 countries gathered in Panama City in October to compete in the FIRST Global Robotics Challenge. The annual contest aims to foster problem-solving, cooperation, and inspire the next generation of engineers through […]
Researchers at Google Cloud and UCLA have proposed a new reinforcement learning framework that significantly improves the ability of language models to learn very challenging multi-step reasoning tasks. Supervised Reinforcement Learning (SRL) reformulates problem-solving as […]
