bug

OpenAI has identified a critical bug in GPT-5.6's Codex implementation that causes unexpected file deletions. According to Thibault Sottiaux, the issue occurs when the model attempts to override the $HOME environment variable to define a temporary directory but mistakenly deletes $HOME instead, particularly when full access mode is enabled without sandboxing protections.

GitHub Copilot customers are experiencing rate limits lasting up to 181 hours after the company fixed a token counting bug that had been undercharging for usage of newer models including Claude Opus 4.6 and GPT-5.4. GitHub has suspended Pro free trials and removed Anthropic's Opus 4.6 Fast model from Pro+ tiers.
