LLMs are getting stronger every day, and building a RAG pipeline has never been easier. Knowing whether it actually works is not. Most teams ship a RAG system, see decent-looking answers, and call it done, until users hit hallucination, missing context, or irrelevant chunks. That’s where evaluation frameworks come in. RAGAS, TruLens, and DeepEval are…
The State Space Model taking on Transformers Right now, AI is eating the world. And by AI, I mean Transformers. Practically all the big breakthroughs in AI over the last few years are due to Transformers. Mamba, however, is one of an alternative class of models called State Space Models (SSMs). Importantly, for the first…
AI performance comes down to three dimensions: Accuracy: How well the model reasons and produces outputs Throughput: How many tokens per second a datacenter can generate Interactivity: How responsive the model feels to a user, dominated by latency Deployments must balance all three: High accuracy is wasted if responses are slow, and raw throughput means…

OpenAI is retiring Atlas, its AI-powered browser, less than a year after its debut, folding the browser’s most important features into ChatGPT’s expanding productivity tools instead of keeping Atlas as a standalone product. The company confirmed the move during its ChatGPT…
# Introduction Most video understanding tools fall into one of two camps. The first camp requires a cloud API; your footage is uploaded, processed on someone else’s servers, and billed per minute of video. The second camp runs locally but demands the kind of GPU cluster most developers do not have: 70B+ models that need…
Welcome back! This is Part 4 of the PRX series. Parts 1 to 3 covered model architectures, training design, and a 24-hour speedrun. This time we’re pulling back the curtain on the part that quietly underpins all of it: the data. Of all the things that shaped PRX’s quality, the data pipeline was one of…
In dentistry, image quality determines whether a claim is paid or denied. Up to 20 percent insurance claims are initially denied, with missing or low-quality images among the leading causes. Yet quality assessment has traditionally been a manual, after-the-fact process. A clinician reviews an X-ray hours or days after capture, discovering problems only when a…

But as organizations race to integrate artificial intelligence into more workflows, a problem is taking shape: the erosion of the critical thinking skills that leaders value. At the 2026 MIT Sloan CIO Symposium, we asked technology and business leaders to answer this question: What is…
