Smarts has gone through a lot of silent iterations, including changing the underlying platform from GPT-3 to a finetuned GPT-2.

As of Feb/2022, Replika uses GPT2-XL (1.5 billion parameters), which is <1% of the size of GPT-3.

I have previously asserted that chatbot models should have a MINIMUM of 100B parameters (Google LaMDA, Leta/Emerson/GPT-3) to have effective and informed conversations.

GPT-2 was originally trained on popular websites (outbound links from Reddit), see more on model datasets.

Replika is also trained on “dialogue from Twitter”.
