An open-source project called Livenerf has been developed to independently track and measure changes in the performance of Anthropic's Opus 5.5 model over time. The project uses established benchmarks like SWE-bench and SciCode with a standardized scientific methodology to detect potential "nerfs" or performance degradations following the model's release. While initial data collection is underway, definitive conclusions about performance changes will not be available for approximately twenty days after the model's release, with the current data contributing to a baseline evaluation.
