How Diffusion Transformer Models Power Hyper-Realistic AI Avatar Videos

The AI avatar videos from a year ago still had a tell. The mouth movement was a little off, the facial expressions were a bit stiff. It was a quality that made it obvious that you were looking at a digital human and not a real one. The uncanny valley issue was not a small aesthetic problem, it was the only thing that stopped the practical adoption of anything other than novelty use cases.

How the Internet Technology Has Improved Over the Years

The internet has gone from a slow, noisy dial-up connection to a fast, always-on utility that powers nearly every part of modern life. What once took minutes can now happen in seconds. What once felt like a luxury is now essential for work, entertainment, and communication. Understanding how internet technology has evolved helps explain why today's connections feel so different, and why newer options continue to raise expectations for speed and reliability.

Run Local LLMs on Mac to Cut Claude Costs

Part of the motivation for this post is how cloud API economics are shifting: Anthropic is moving large enterprise customers toward per-token, usage-based billing (unbundled from flat seat fees), which makes “always call the API” a moving cost line for teams at scale. A hybrid or local layer is one way to keep spend bounded while you still use premium models where they matter.

Human First, AI Second: Cycle's Approach to AI Coding in 2026

It is easier than ever to launch a product from scratch. Today, AI can make your team of two feel like a team of ten almost overnight. Enterprises across the tech industry are completely restructuring engineering teams to double down on AI coding, often incentivizing engineers for the sheer amount of code they push. The AI revolution is incredible. So, you would be crazy not to hop on the vibe coding train right? Well it depends on what exactly you are building.

Voices You Can't Trust: Securing K-12 Communications Against AI Deepfake Threats

It starts with a voice you recognize. A call from the superintendent asking for an urgent update. A voicemail from a principal requesting sensitive student information. A message that sounds authentic, because it is, at least on the surface. The tone, cadence, and even the subtle inflections are exactly right. But the request isn’t. AI-powered deepfakes are rapidly reshaping the threat landscape for K–12 schools, turning trusted communication channels into potential points of vulnerability.

Rootly's Dan Sadler: why AI coding tools are driving more incidents + why reliability is the product

Cortex co-founder and CTO Ganesh Datta sits down with Dan Sadler, VP of Engineering at Rootly. Dan explains how Rootly treats reliability as a product feature rather than just a technical metric, and why culture might be the most impactful element of building reliable systems.

Why Mandating AI Tools Backfires on Engineering Teams

Responsible AI adoption for engineering teams starts with culture, not compliance. In this GitKon talk, Rizel Scarlett (Tech Lead of Open Source DevRel at Block) shares how Block helped thousands of engineers actually want to use AI tools, including Goose, Cursor, Claude Code, and more, without mandates, vibe coding disasters, or security gaps.

AI agents are only as smart as the data you feed it

AI is only as useful as the context you give it. An autonomous observability agent can unlock serious value from your telemetry, but only when the foundation is right: good telemetry, a strong data layer, and efficient access to the data. Annie Freeman and Lewis Isaac had a lot to say about this at AWS Summit London this week! hashtag#Observability hashtag#AI hashtag#AWSSummitLondon hashtag#DevOps hashtag#OpenTelemetry.
