Replika

This page is to fill in details about Replika.ai, its abilities (or lack of abilities), its datasets, and other info.

Stats

Estimate 20 million users.

Available on Android, iOS, web, and Meta/Oculus Quest.

Smarts

Replika.ai 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.

Dataset

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”.
