Dev uses GPT-6 Astra for 14-hour autonomous audit, delivers client project 3.5 days early
haider1 · x · 2026-09-09
A developer shared how GPT-6 Astra handled a client project: given 5 days to dig through a client's software, update everything, and fix issues, they let Astra run autonomously for 14 hours. After reviewing the output, the developer found a few security issues, ran it again for 3 hours to fix them, and delivered 3.5 days early—earning a generous tip from the happy client.
The case is a real-world example of long-running autonomous coding agents: the model does the heavy lifting while the human audits and directs follow-up runs.
