Google has released a neural-network powered chatbot called Meena that it claims is better than any other chatbot out there. Data slurp: Meena was trained on a whopping 341GB of public social-media chatter—8.5 times as much data as OpenAI’s GPT-2. Google says Meena can talk about pretty much anything, and can even make up (bad) jokes. Google says it won’t be releasing a public demo until it has vetted the model for safety and bias, which is probably a good thing. When Microsoft released its chatbot Tay on Twitter in 2016 it started spewing racist, misogynistic invective within hours.
