I Built a Stateful Research Agent Inside a Sandbox. Here's What the Numbers Actually Looked Like.

A research agent that keeps its state in a Tensorlake sandbox: it survives restarts and resumes mid-task, with real latency numbers throughout.

Divy builds a research agent that keeps its working state inside the sandbox rather than in the harness, then kills it and restarts it to prove it resumes mid-task. What makes it worth the read is the instrumentation: real latency numbers at every step, not vibes.

We didn’t write this one — it’s Divy Yadav’s piece, published on Towards AI. The note above is ours; the full article is theirs.

Tensorlake Sandboxes as the runtime for Claude Managed Agents.Run Claude Managed Agents on Tensorlake Sandboxes: you keep the control of self-hosting, and drop the always-on box. The short version — the server goes away.

Filter and rank: how we schedule sandboxes across every cloudOne primitive — filter, then rank — runs through statefulness, multi-cloud, BYOC, and the data path. A tour of the scheduler behind Tensorlake's sandbox fleet.

Browser Harness: direct Chrome DevTools Protocol access and a self-healing harness for browser agentsBrowser-use strips their harness to 592 lines and gives the LLM a raw WebSocket to Chrome's DevTools Protocol. When the agent hits a gap, it writes a helper function — and saves it for future runs.
