Based on the first signs it seems to be as good as the best competing bots from Google and Microsoft.
The Facebook reportedly used a huge amount of information and trained AI. Blender chatbots are open source, which means they can't be trained just to answer a certain set of questions, like the ones you see on websites.
These bots are theoretically capable of talking about any topic.
A post from the company blog states:
This is the first time a chatbot has learned to combine several chat skills, such as the ability to have a personality, discuss almost any topic and show empathy - in natural chat streams.
Our new recipe incorporates not only large-scale neural models with up to 9,4 billion parameters - or 3,6 times more than the largest existing system - but equally important skills combination techniques and detailed discussion.
The number of parameters used by Blender plays a big role in how convincing each AI discussion is. AI requires more computing power, but it produces significantly better results.
According the page of the Blender project:
Good conversation requires a set of skills that a skilled interlocutor combines seamlessly: Provide attractive points in the speech and listen to the collaborators, ask and answer showing that he has the necessary knowledge, has empathy and personality, depending on the occasion . It seems that large-scale models can learn these skills when given the right training data and a choice of strategy.
The result is a chatbot that can convincingly reproduce human conversation. In a way, it is capable of passing the Turing Test. This may well represent the most advanced AI chat on the planet.
OR Artificial Intelligence of Facebook he does not understand a word of what he says. He does not "listen" to anyone, he cannot understand the language or the meaning behind the words. It only makes the correlations between the statements given to it by its developers and deems them to be the appropriate answers to a topic.
He may not be "knowledgeable" because he does not actually use a limited database, but he makes correlations that seem to make sense. For example, if you say that your favorite song is one of Smashing Pumpkins, he may say that he likes a different song better. But he has never listened to music. Edits only natural language. He does not understand what sound, images or video are.
He also has no empathy, he can not analyze your feelings or express his own. He simply responds with statements that he has been trained to understand as representing the appropriate answers. If, for example, you say you are sad, he will not say "congratulations", or "and time."
Basically, the Artificial Intelligence of Facebook he seems to be becoming a perfect liar because he has no other choice. Artificial intelligence does not feel or think, so it can not experience. Thus without experience, it will not become human. The bot will have to lie in order for a person to "play" it.
There may come a time when perhaps humanity regrets its decision to create bots of artificial intelligence. The biggest danger, however, is not the bots who will use their knowledge to harm us, but the people who can do it.
