Reliable enough to start your morning with. Toast it again tomorrow.
Summary
This article describes an independent performance tracking system for Claude Code Opus 4.6 on software engineering tasks. The tracker aims to detect statistically significant performance degradations by running daily evaluations on a contamination-resistant subset of SWE-Bench-Pro. The initiative was motivated by Anthropic's September 2025 postmortem on Claude degradations, and the tracker serves as an independent monitoring resource using the latest Claude Code releases and state-of-the-art models.
