Codex Becomes More Stable for Multi-File Tasks
jxnlco · x · 2026-07-15
A user reported switching to Codex in early June, as GPT-5.5 was already handling large-scale, multi-file tasks well. After upgrading to GPT-5.6 Sol, repo comprehension, debugging, and continuous execution improved significantly, prompting them to set it as the default tool and even cancel Claude.
This essentially highlights that in real-world engineering workflows, pairing Codex with newer models offers a more stable and sustainable experience for complex repo tasks. The original post also noted that officials are incentivizing users to share their switching reasons with $100 Codex credits.
