## Main Purpose

This Liaison Statement informs all 3GPP working groups about the completion of the Study on AI/ML consistency alignment.

## Technical Contributions

### Study Completion

TSG SA has completed the Study on AI/ML consistency alignment, with the following deliverables:

1. **TR 22.850 v1.0.0** - The technical report documenting the study findings was approved at SA#110
2. **CR 0128 on TR 21.905** - A change request to TR 21.905 was approved to establish consistent AI/ML terminology

### Terminology Standardization

The key technical contribution is the definition of **consistent AI/ML terminology** to be used across all 3GPP working groups. This terminology has been captured in the approved CR to TR 21.905, which serves as the 3GPP vocabulary specification.

### Work Item Closure

- No further work is planned on this study activity
- The study item FS_AIML_CAL is considered complete

## Actions Requested

TSG SA requests all recipient groups (TSG RAN, TSG CT, and all SA, RAN, and CT working groups) to:
- Take note of the completed study
- Apply the standardized AI/ML terminology defined in the updated TR 21.905 in their respective work
