Telemetry-driven development: How to gain confidence in your coding agents' behavior with gcx and Grafana MCP
You’re about to click "Merge" on a PR, but you feel more anxious about it than you used to. Why? You did everything properly, by today’s standards: You used Claude to create a plan, giving it context from a GitHub issue and some Slack threads. You iterated on it a few times; Claude says it has the f...

The Orchestrator's Tax
Subagents get justified by time saved and parallel execution, but Rahul Garg explains that's not what matters most. Every token in the orchestrator's context is competing for its attention, and the real value of a subagent is what it keeps out of that context. Subagents should be treated as a tool f...
Why I’m Writing Rachel’s Ramblings
TL;DR I have ideas. I haven’t been writing them. That’s about to change. I promise… myself. I’ve been thinking a lot about talent. Actually, I’ve been thinking a lot about thinking. And writing. Or more specifically, not writing. This really hit me earlier this year at the Future of Software confere...
Investigate every security event with an AI agent, without the frontier bill
Learn how Datadog built Mambark, a small state-space model that scores every security event and enables heavier AI agents to investigate only the events that matter.

Smarter onboarding and planning with Grafana Assistant: How to ensure observability is baked in from the start
It's Monday afternoon and that feature you've been working on is mostly done. There's just one item still sitting untouched at the bottom of the ticket: "Add monitoring." You know you should. You also know the sprint ends tomorrow, nobody on the team is an observability expert, and figuring out what...
How NVIDIA Builds Open Models for the Age of AI
Bryan Catanzaro, VP of Applied Deep Learning Research at NVIDIA, walked us through how his team builds the company’s open models, the reasoning behind their architecture, and why NVIDIA open-sources so much of it.
Explore what's next in agentic operations: Introducing AI Week
For a full rundown of all the new features we announced (including a few not listed here), check out my AI Week recap blog post . Observability has traditionally been tacked on after your code hits production, but with agentic operations on the rise, that's no longer sustainable. Agents have dramati...
