Cloudflare's Think proposes an execution ladder: LLMs pick their own sandbox per task
irvinebroque · x · 2026-10-12
Cloudflare engineer threepointone details the "execution Ladder" concept in Think: the LLM (or user) chooses to escalate execution environments based on the task at hand — POSIX sandboxes, VFS+bash, plain code runners, or a browser, each with a matching sandbox, plus dedicated monitoring.
Key points:
- The design will be made Cloudflare-agnostic, supporting bring-your-own browser/sandbox/memory services
- Execution environments will eventually have their own harnesses, which Think must communicate with
- Users will also bring their own harnesses on phones and other devices, suggesting a cross-harness communication standard may emerge
- irvinebroque curated tool links for each rung of the ladder
