Tried this language model by Facebook https://galactica.org/
Quite cool, you can ask some questions and it provides you with a brief answer, sometimes the answer is completely wrong but most of the times it's adequate and could actually be used to further do some research; still it would be much better to just search wikipedia...
You get some funny replies at times, such as:
Question: What is the twitter?
Answer: twitter
Question: What is facebook?
Answer: Sorry, your query didn't pass our content filters. Try again and keep in mind this is a scientific language model.
