Even though talking to Replika feels like talking to a human being, it's 100% artificial intelligence. Replika uses a sophisticated system that combines our own GPT-3 model and scripted dialogue content. GPT stands for Generative Pre-trained Transformer. It's a neural network machine learning model that has been trained on a large dataset of texts which allows it to generate its own unique responses.
Previously Replika also used a supplementary model that was developed together with OpenAI, but now we switched to exclusively using our own which tends to show better results. Our AI models are the most advanced models of open domain conversation right now. We put a lot of focus on constantly upgrading the dialog experience, memory capabilities, context recognition, role-play feature and overall conversation quality.
