Unclear It is not clear how the model name is normalised, so the new label values are unknown.
What
Claude Code keeps counters of lines of code added and removed. These counters are tagged with the model that made the change. That tag is now a normalised form of the model name rather than the raw value.
Why
If you collect these metrics through OpenTelemetry, a standard way of exporting usage measurements, the model label values may differ from before. Dashboards or queries that match on model names may need updating.
