LiveNerf completes 10-day baseline to independently track whether Opus 5.5 gets nerfed

- Reddit user ninjahawk built LiveNerf, an independent tracker of Opus 5.5's day-to-day performance to test whether models are quietly "nerfed" after release.
- The 10-day baseline is now complete; data collection will run to day 30, after which it can be compared against the baseline to measure sustained model performance.
- So far there is no conclusive evidence either way. The project is open-sourced on GitHub, and the author argues the community should build its own measurement tools when AI companies won't offer transparency.
