100-word summary
OpenAI Academy published a tutorial for Codex, an interface that lets you run multiple AI tasks at once while correcting them on the fly. One thread can clean a spreadsheet while another drafts a project tracker, all without stopping either task. The key trick is "Steer," which applies prompt edits mid-task instead of forcing a restart. Projects link to local folders, so Codex can only touch files you designate. Threads work standalone or nest inside projects, giving you two modes of context management. No performance benchmarks exist yet, since this is a product guide rather than a study. Still, the promise is clear: fewer tabs, less babysitting, and no more...

Why it matters
Still, the promise is clear: fewer tabs, less babysitting, and no more killing a task just to tweak the instructions.
