The model architecture design, pretraining, and evaluation are documented in our preprint: A Family of Pretrained Transformer Language Models for Russian.

The model was pretrained with sequence length 1024 using the Transformers library by the SberDevices team on 80B tokens for 3 epochs. After that, the model was finetuned with the context size of 2048 tokens.

Total training time was around 16 days on 64 GPUs.
The final perplexity on the test set is 17.4.
