t-bank-ai/ruDialoGPT-medium

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)

	sensibleness	specificity	SSA
tinkoff-ai/ruDialoGPT-small	0.64	0.5	0.57
tinkoff-ai/ruDialoGPT-medium	0.78	0.69	0.735
