In this tutorial, we build an in-depth NeMo Guardrails pipeline that demonstrates how layered guardrails can control an LLM-based financial assistant across the full request lifecycle. We combine deterministic PII detection and redaction, LLM-based input and output self-checks, retrieval filtering, account-number masking, topical restrictions, and policy-based tool gating. We also implement stateful multi-turn interactions, detailed…

As Harvard Business School seeks to expand its reach, it’s leaning on AI avatars to provide individual feedback. These avatars were created by a startup called HeyGen and are included in the eight-week, $699 HBS Foundry bootcamp for entrepreneurs. The program offers live sessions with instructors every week, but the AI avatars are the ones…

Following a Bloomberg report that the Department of Justice is investigating venture firm Andreessen Horowitz for holding board seats with rival AI companies, VCs told TechCrunch that they were baffled. On the latest episode of the Equity podcast, Kirsten Korosec, Sean O’Kane, and I were similarly puzzled by the news. Yes, VC conflicts-of-interest are worth…

Inherent, a London AI lab founded by Google DeepMind alumni, says its AI agent just outperformed much larger models from Anthropic and OpenAI using a fraction of the size. Of all the startups launched by Google DeepMind alumni, Inherent has gotten relatively little attention. But while better-funded rivals have yet to show the world anything…

If you buy the new Pixel 11 Pro, you might have to proactively tell people that you bought the latest phone, unless they are following each and every launch. The main reason is that the Pixel 11 doesn’t look that different from prior models. The main updates to its aesthetics are its new colors, which…

OpenAI is calling for California to add more safeguards to a landmark AI safety bill that was passed last year. In a LinkedIn post from the company’s global affairs team, OpenAI said California’s SB 53 “should be amended to expand safeguards,” for example by “requiring monitoring of frontier models under training or evaluation for potential…

Few of the top AI labs have published or demonstrated containment response plans, according to a recent study. A containment plan spells out what happens once an AI is caught trying to subvert human control — what access gets cut, and when the system gets shut down entirely. That’s the finding from Guidelight AI Standards,…

U.S. battery startups hit a rough patch when the One Big Beautiful Bill eliminated battery and EV incentives, undercutting a chunk of future demand. But recently, they’ve found a lifeline in the defense world, helping to power everything from drones and torpedoes to infantry radios and fighter jets. The Trump administration, despite its open disdain…

Most teams treat ‘which model’ as the important decision. The harness engineering literature keeps pointing somewhere else. In LangChain’s Terminal-Bench experiment, changing only the harness—same model throughout—moved a coding agent from roughly 30th place into the top 5. That result reframes the question. If the harness decides quality, then how you run the loop becomes…
