AI Developer Advocate at Google Cloud. Instructor @DeepLearningAI. Startup Advisor @ycombinator. Cloud TPU, Agent Platform Engineering and AI for science.
Presenting at the Next '26 Developer Keynote is one of those moments I'll remember for a long time.
Thank you to everyone who played a part.
Till the next Next!
The Agent Substrate ecosystem is growing fast.
kagent, the open source agent framework for Kubernetes, reached 1.0 this week: its agents run on Agent Substrate, sleep when idle, and now any MCP client can discover and call them.

Pathways on Google Cloud is now generally available
It runs JAX programs on Cloud TPUs with one Python client that lets you debug, coordinate many programs, and recover from failed hosts
I'm personally proud of this launch because I got to work with one of the great TPU engineering teams at Google

Google Cloud TPU news:
1️⃣ New TPU systems with 8i Max (long context) and 8tx (confidential inference)
2️⃣ TPU Sync, an open source KV cache offload for inference
3️⃣ Cloud Pathways in GA to run JAX with one Python process on many TPU slices
4️⃣ GKE dynamic slicing in GA to reshape TPU slices without new nodepools

WE ARE LIVE with Google’s Chief Technologist of AI Infrastructure, @AminVahdat, to share more details on our new TPUs.

Coding agents seem to mostly wait. In a study of agent traces by Banruo Liu and colleagues, a typical session with several prompts spent about 80% of its time waiting for the user.
Agent Substrate can snapshot the agent while it waits and give its sandbox back to a warm pool on Kubernetes. It is now 1.0, GA on GKE, and in the CNCF 🧵
We've been thinking about building an AX Studio which makes it easier to create a local cluster and test things locally. Once tested locally, agentic tasks can be run against a production cluster without changes.
We're open-sourcing Autopilot.
A self-improving agent that plays your game and finds bugs. Unity, Godot and Unreal.
→ 43% more accurate
→ Almost 2X faster
→ Beats Claude Code at playtesting
It’s Computer Use for games – closing the agentic loop and solving the most tedious part of game dev.

I was really happy to present and discuss AX and Agent Substrate at the AGNTCon + MCPCon NA last week
With AX and Agent Substrate, coding agent runs as a session that:
- gets its own sandbox
- holds no resources while asleep
- wakes fast on a warm resources

With AX, you declare each session once as a task, then start, check, or suspend it with kubectl style commands.
With Agent Substrate, the runtime keeps a suspended session as a snapshot in object storage and brings it back with its files and conversation.
