Codex Agent Codes Low-Level Library for 4 Hours, Autonomously Fixes Algorithm Bug
___Patrice___ · x · 2026-08-08
A developer shared an impressive experience using the Codex agent: in just 4 hours, the agent not only completed the development of a low-level library for file parsing, A/V processing, and multiplexing, but also autonomously investigated and reproduced a weirdness in the MMX Lanczos resize algorithm to ensure matching output hashes. This capability of autonomously troubleshooting complex low-level bugs highlights the immense potential of AI coding agents in long-running, highly complex tasks.
