The big news: **Grafana Agent Observability is now generally available.** This is the tool we built for ourselves while scaling Grafana Assistant, when it grew too complex to evaluate with unit tests. Now it's available to everyone on Grafana Cloud. Here's how it works: instrument your agent with the SDK, and your conversations, tool calls, traces, latency, token use, and cost all become observable in one place. Then add evaluators — LLM judges plus deterministic checks — to score quality on live traffic. Low-scoring conversations feed your test suite, and experiments let you compare a candidate against a baseline before you ship — you can even make it a CI gate. And because evaluator metrics land in Prometheus, you can get paged if a bad prompt change tanks quality in production. But my favorite part of today? **k6 agentic testing.** Describe a browser test in plain natural language, and an agent embedded in k6 drives the browser for you — no script at all. And to prove it, we gave it one job: beat Wordle. Go watch that video. I'll wait. Everything's at **grafana.ai** — see you tomorrow for the finale: using AI where your team already works.
