# FRED-T5 1.7B (Full-scale Russian Enhanced Denoisers T5) 

Architecture based on T5. 

It has 24 layers and 1536 hidden size.

Model trained on a mixture of 7 denoisers like UL2 with several differences (https://arxiv.org/abs/2205.05131).

It trained on Russian language corpus (300GB).   Dataset is the same as for ruT5 models. 

Bbpe tokenizer. 

First half of the time model trained on the small part of all datasets (1%,3GB) and without prefixes in each task.

For RSG we trained as described in the T5 paper. First, we trained multitask for all tasks. Then we took the best checkpoint for the task and trained it further.

Training loss:

We continue to experiment... 

We'll tell you more  and release  checkpoint  to the public soon.
