ruDialoGPT-medium

like 28

This generation model is based on sberbank-ai/rugpt3medium_based_on_gpt2. It's trained on large corpus of dialog data and can be used for buildning generative conversational agents

The model was trained with context size 3

On a private validation set we calculated metrics introduced in this paper:

• Sensibleness: Crowdsourcers were asked whether model's response makes sense given the context
• Specificity: Crowdsourcers were asked whether model's response is specific for given context, in other words we don't want our model to give general and boring responses
• SSA which is the average of two metrics above (Sensibleness Specificity Average)

How to use:

import torch
from transformers import AutoTokenizer, AutoModelWithLMHead

tokenizer = AutoTokenizer.from_pretrained('tinkoff-ai/ruDialoGPT-medium')
model = AutoModelWithLMHead.from_pretrained('tinkoff-ai/ruDialoGPT-medium')
inputs = tokenizer('@@ПЕРВЫЙ@@ привет @@ВТОРОЙ@@ привет @@ПЕРВЫЙ@@ как дела? @@ВТОРОЙ@@', return_tensors='pt')
generated_token_ids = model.generate(
    **inputs,
