Amazon S3 annotations: attach rich, queryable context directly to your objects

Amazon S3 now lets you attach up to 1 GB of rich, mutable, and queryable context directly to your objects using annotations, purpose-built for AI agents and autonomous workflows that need to discover, understand, and act on data at scale without maintaining separate metadata systems.

Foundation vs. Instruct vs. Chat Models: One Question, Three Answers

A hands-on tutorial you can run for free in Google Colab. Run it yourself: open foundation_instruct_chat_tutorial.ipynb in Google Colab and run every cell top to bottom. It uses the SmolLM2-135M family — small enough for a free CPU runtime, no GPU needed. People say "LLM," "GPT," "an AI model," and "ChatGPT" as if they were the same thing. They aren't. There's a ladder of training stages between "a model that read the internet" and "an assistant you can chat with," and the words foundation, inst

We built an app for Japanese neighborhood associations — and the handover notebook turned out to matter most

The problem Every year in Japan, a small group of volunteers runs the local 自治会 (neighborhood association). They circulate bulletins, collect dues, check in on elderly residents, run votes at general meetings, and maintain the annual schedule. At year's end, they hand the role over — usually with a folder of paper, or nothing at all. Nobody tracks who did what. Nobody measures the actual workload. So when it's time to recruit the next round of officers, no one can honestly answer "how much wor

Product Launch Telemetry: How AIKit Turns Feature Releases Into Agent-Readable Growth Loops

Product launch telemetry is the bridge between shipping a feature and proving that the feature created growth. AIKit can turn every release into an agent-readable loop by publishing the launch page, instrumenting CTA events, summarizing customer signals, and feeding the next experiment back into the roadmap. Most product launches create a burst of activity and then lose the evidence. A team ships a feature, posts an announcement, watches a few dashboard numbers, and moves on. Two weeks later nob

Zero Variance: Proving COBOL-to-Java Semantic Equivalence with a Live Mainframe Emulator on AWS

By Banu Parasuraman Distinguished Engineer | Account CTO | Mphasis "The mainframe isn't going away. But the teams who understand it are. The window to modernize safely — before institutional knowledge walks out the door — is closing." Mainframe modernization is one of the most consequential — and most feared — programs in enterprise IT. Billions of dollars of financial transactions flow daily through COBOL batch jobs that have been running, largely unchanged, for three to four decades. The fear

I'm building CortexDB — an agent-native context database for AI agents

I'm building CortexDB — an agent-native context database for AI agents Most modern RAG systems work like this: Split documents into chunks Generate embeddings Store them in a vector database Retrieve top-k similar chunks on query Send them to an LLM It works for simple use cases. But as AI agents become more autonomous and complex, a clear problem appears: Agents don’t just need similar text chunks. They need bounded, permission-safe, evidence-aware, and verifiable context. This is why I
