Just saw a single billboard in SF that didn’t have the word “agent” or “ai” on it. Is this a recession indicator?

OpenTelemetry in @code keeps getting better!
We heard your feedback you wanted ready-made dashboards for visualizing agent metrics. We partnered with the Azure Managed Grafana team to provide some dashboards to get you up and running quickly.

VS Code uses 'utility models' for tasks like generating a chat title or a commit message.
This model is now configurable with the chat.utilityModel and chat.utilitySmallModel settings :)

Testing out our built-in mermaid support in @code that @mattbierner worked on and it's kinda crazy how views like this are possible.
Ask chat to output a mermaid diagram, pop it into the editor and get a closer look.
Works in Agents window as well.

We believe the agent harness in @code to be best in market today.
Today, the team shared a behind-the-scenes look at our harness optimization efforts, including our own offline evaluation suite vsc-bench:

🧠 The conversation around AI for developers usually starts with the model.
But inside @code, what really shapes the experience is the coding harness: the layer responsible for context, tool calling, agent loops, terminal execution, memory, and more.
In this new post, the engineering team dives into how GitHub Copilot in VS Code works behind the scenes.
