  We introduce Spivavtor, a dataset, and instruction-tuned models for text
editing focused on the Ukrainian language. Spivavtor is the Ukrainian-focused
adaptation of the English-only CoEdIT model. Similar to CoEdIT, Spivavtor
performs text editing tasks by following instructions in Ukrainian. This paper
describes the details of the Spivavtor-Instruct dataset and Spivavtor models.
We evaluate Spivavtor on a variety of text editing tasks in Ukrainian, such as
Grammatical Error Correction (GEC), Text Simplification, Coherence, and
Paraphrasing, and demonstrate its superior performance on all of them. We
publicly release our best-performing models and data as resources to the
community to advance further research in this space.
