Sub8
Computer-use agent on its own Linux VM.
Isolation so the model can act without owning the host. Model-agnostic sandbox for coding agents.
Daniel Farina
I build the layer around the model — sandbox, tools, evals, control plane — and publish what actually breaks.

Selected work

Xplor
Chromium fork with an agent gateway.
CDP + API so agents browse and build in-tab — not a chat overlay bolted onto Chrome.
GrokTerm
PTY host for coding agents with voice.
Multi-tab terminal, two-way Grok Voice, notarized Mac app — drive agents without living on a keyboard.
grok-remote
ACP control plane over a tailnet.
Remote agent sessions with a real UI — supervisor/worker shaped, not a single chat pane.
grok-bench
Prompt diffs, compaction, proxy observability.
Measure where tool-call loops and long-context workflows actually break.
ThinkVoice
Speak without moving your mouth — Grokathon.
Grok Voice + sensing; blink/nod select. SpaceXAI Grokathon 2026: 3rd place and Most Users.
Writing
All writing →Essay Talk, don't block: splitting the coding-agent composer from the worker
The thing you talk to should not be the thing holding the write lock.
Essay Sub8: give the agent a computer it cannot escape
Computer-use is easy. Isolation is the product.
Essay Fork the browser. Don't bolt on an extension.
If the agent is a guest in Chrome, you already lost.
Essay Drive a coding agent from the other machine
ACP over a tailnet. Session survives disconnect.
3,500 lines of 3D game logic from a single Grok 3 session
Long-horizon tool use on XForce — where Grok 3 held and where it didn't.
