The subdivision of the social media & ad giant has built what they claim to be the largest ever open-domain chat bot, or what they call it the BlenderBot.

Aside from the “usual” machine learning and AI technology used in the bot, it is focused on simulating an empathetic, engaged personality that displays knowledge as well. All of that is achieved by “blending” different tasks within the bot.

The code for ParlAI is on GitHub and you can create conversational recipes and tweak them yourself.

There are no practical applications for the bot yet, though it may be implemented as part of other Facebook services, which would be great for general chatbot adoption.
