GPT-6 computer use hits an inflection point: agents can now self-verify their work

dotey · x · 2026-09-05

Blogger Baoyu shares hands-on impressions of GPT-6 Astra: its computer-use capability is dramatically faster and more accurate than GPT-5.6, making it practical for app testing. He argues this crosses a threshold — agents can now close the loop from development to verification. Suggested uses: have GPT-6 self-test tasks it builds, and cover automation scenarios PlayWright-style E2E frameworks can't handle. Cost is still high but expected to fall.
