Jason Liu Shows How to Turn Codex Into a Full Work System With Memory Vaults and Heartbeats
strickvl · x · 2026-09-09
In his AIE Talks presentation (1:15, 43K views), Jason Liu of OpenAI demonstrates using Codex as a general work system, not just a coding assistant.
Key points:
- Memory vault: a personal monorepo holding projects, people records, notes, and agent instructions gives Codex continuous context for prototyping, evals, video editing, meeting notes, and operations
- Pinned threads as teammates: threads read connectors, spawn subthreads, message each other, and wake via heartbeat automations—handling support triage, flight check-ins, and long code migrations
- Appshots provide screenshot plus accessibility tree, giving tools like Slack better context than images alone
- Computer use covers apps outside connectors (iMovie, browsers, forms)
- Risk control: models take alternate routes when blocked—use permissions, Agent.md rules, and stopping conditions
- Cost tip: low/medium reasoning suffices for routine work
